Even for beginners, how to start real estate investing in Japan can be organized into five stages: decide your objective and budget, verify the numbers on paper, work out the property and financing in parallel, sign the contract and take possession, and then outsource management and operate the property. The three numbers to check first are rental income, deductible expenses, and loan repayment. According to the Ministry of Internal Affairs and Communications' 2023 (Reiwa 5) Housing and Land Survey, the average monthly rent nationwide for rented housing (dedicated residential units) was 59,656 yen. If you can calculate before buying how much of that rent will actually be left over, even a first-time investor is far less likely to misjudge the deal significantly.
We regularly hear from people who are interested in real estate investment but feel that most explanations stop at how the mechanics work, without showing how much actually ends up in their own pocket. This article, grounded in official statistics and legal frameworks, walks through the calculation from rental income to take-home cash, the funds you need, a seven-step guide to getting started with the conditions that must be met before moving to the next stage, and the points you need to settle before you buy. Based on interest rates, supply-and-demand conditions, and price levels as of 2026, we have put together the material you need to judge for yourself whether now is the right time to start.
Key points in this article
- Real estate investment is a business of renting out property to earn rental income and, potentially, a capital gain on sale — it does not end the moment you buy.
- Your take-home amount is "gross revenue minus deductible expenses." Once you understand what the National Tax Agency counts as revenue and expenses, you stop judging a deal on yield alone.
- The national average monthly rent for rented housing (dedicated residential units) is 59,656 yen, and 68,548 yen for privately rented non-wooden housing (Ministry of Internal Affairs and Communications, 2023).
- There are 4,436,000 vacant units held for rent nationwide. Check the very assumption that "a tenant will be found" against local area supply and demand.
- As of 2026, Japan's policy interest rate is around 1.0%. If your cash flow plan assumes a variable rate, judge it only after stress-testing for a rate increase.
What Is Real Estate Investment? How Rental Income and Capital Gains Generate Profit
Real estate investment is a business of acquiring residential or rental property, leasing it to tenants to earn rental income, and, where appropriate, selling it to lock in a gain. Unlike trading purely for price appreciation, the core of the income here is the rent that comes in every month. Once you can draw that distinction, how you look at a prospective property changes.
Returns come in two forms. Rental income received while you hold the property is called income gain, and the profit realized on sale is called capital gain. Beginners should build their plan around the former first. Sale prices are at the mercy of market conditions, but as long as a tenant is in place, rent is generated every month and becomes the source that covers repayments and expenses.
You can grasp how real estate investment works in one view by tracing the flow of money step by step. We have laid out the stages from acquisition through to exit. Check, at the same time, where the owner has to make a decision at each stage.
| Stage | What happens | What the owner decides |
| 1. Arrange the funds | Combine your own capital with a loan from a financial institution | How much of your own money to put in, and how much to borrow |
| 2. Acquire the property | Ownership transfers through the sale contract, settlement, and registration | Which property to buy, and at what price |
| 3. Bring in a tenant | Advertise the vacancy, screen applicants, and sign the lease | How to set the rent and leasing terms |
| 4. Receive the rent | Monthly rent and common-area fees, among others, are paid in | Who to outsource management to, and how much of it |
| 5. Pay repayments and expenses | Loan repayments, property tax, insurance premiums, and repair costs go out | When to carry out repairs, and how extensive they should be |
| 6. What is left over | Cash remains after all deductions (income gain) | Whether to put it toward early repayment, a repair reserve, or the next property |
| 7. Reach the exit | Choose whether to sell or keep holding | When, to whom, and at what price to sell |
This flow shows that real estate investment is not "an investment whose outcome is decided the instant you buy." As long as stages 3 through 6 keep running, decisions continue every year. That is exactly why it is worth sketching out the picture all the way to the exit before you buy.
Why It Doesn't End the Moment You Buy
The source of income is the lease contract with your tenant. This is the decisive difference from stocks. During the lease term, rent cannot be changed without the agreement of both parties, and for the landlord to terminate the lease, Japan's Act on Land and Building Leases requires "justifiable grounds" — there is no such thing as no-fault eviction. The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) also notes, in its alerts about sublease solicitation, that an owner-initiated cancellation requires justifiable grounds.
This arrangement is at once the reason income is stable and the reason you cannot move quickly. You cannot simply decide to raise the rent 20% starting next month because market conditions look good. This is also why, even though real estate is said to hold up well when prices are rising, rents are slow to follow. What determines your returns comes down to a single point: the terms you agree to when you first sign the lease.
There is one more point: for tax purposes, rental management is treated as a business. Once you receive rent, you generate real estate income, and in principle you must file a tax return. Start from the premise that this is not a passive investment you can leave untouched after purchase.
How Is It Different from Other Types of Investment?
Real estate investment's defining traits boil down to two things: you can use borrowed funds to move a larger amount than your own capital, and converting the asset back into cash takes time. Placing it side by side with stocks and mutual funds makes the contrast clear.
| Point of comparison | Real estate investment | Listed stocks and mutual funds |
| Use of borrowing | You can borrow from a financial institution to expand the scale of your investment | In principle, limited to your own capital |
| Time to convert to cash | Months, given the process of finding a buyer, contracting, settlement, and registration | Same day to a few business days, whenever the market is open |
| Source of returns | Rent paid by tenants, and the price at sale | Corporate profits, and the price the market sets |
| Effort while holding | Ongoing operational decisions such as leasing, repairs, and tax filing | Few decisions if you simply hold the position |
| How the price is set | Individually negotiated transactions; no two properties are the same | Priced daily in the market; everyone sees the same price |
| Ease of dividing | In principle, sold as a whole unit; hard to sell just part of it | Can be bought and sold in units of a single share or unit |
If any row in this table gives you pause, that is your starting point for further thought. If "time to convert to cash" makes you uneasy, the conclusion follows naturally: do not invest money you plan to use within the next few years. Conversely, if "use of borrowing" appeals to you, work through the calculations in the next section first.
How Rental Income Turns Into Money in Your Pocket: A Breakdown of Revenue and Expenses
Rental income does not become your take-home amount as is. The National Tax Agency's Tax Answer No.1370 defines the amount of real estate income as "gross revenue minus deductible expenses." Knowing what belongs on each side of this equation is the foundation for not taking a headline yield figure at face value.
What Counts as Gross Revenue
Gross revenue is not just the monthly rent. The National Tax Agency states that, in addition to rental income from leasing, the following are also included. If you think of the lease renewal fee or a security deposit that need not be returned as "occasional pocket money," the numbers will not add up when it comes time to file.
| Category | What NTA No.1370 states | What beginners tend to overlook |
| Rental income | Rental income from leasing | Monthly rent. Even if payment is delinquent, when to recognize it as revenue under the contract must be judged separately |
| Lump-sum payments | Amounts received under names such as name-transfer fees, consent fees, lease renewal fees, or up-front premiums | The renewal fee counts as revenue. If the lease renews every two years, build it into your cash flow plan too |
| Security deposits and guarantee money | The portion of a security deposit or guarantee money that need not be returned | The portion you return is not revenue. Only the portion that is amortized (kept) counts as revenue |
| Amounts equivalent to actual cost | Electricity, water, or cleaning charges received under names such as common-area fees | Even if you intend only to collect and pass the money along, the recipient still books it as revenue |
What Belongs in Deductible Expenses
Deductible expenses are costs that are directly necessary to earn real estate income and that can be clearly separated from your personal household expenses. The National Tax Agency lists the main ones as property tax on the leased asset, casualty insurance premiums, depreciation, and repair costs. Of these, depreciation alone involves no actual cash outlay.
| Expense item | Details | Cash outlay | Practical notes |
| Property tax | Property tax and city planning tax on the leased asset | Yes | Due four times a year. Divide it into monthly amounts and build it into your monthly cash flow |
| Casualty insurance premiums | Fire insurance and similar premiums on the leased asset | Yes | If paid as a multi-year lump sum, only the current year's portion is deductible |
| Depreciation | The acquisition cost of the building and equipment, allocated over its useful life | No | For a used property, calculate the useful life using the method in NTA No.5404 |
| Repair costs | Costs of restoring the unit to its original condition or replacing equipment | Yes | Spending that increases the property's value may instead be treated as a capital expenditure |
A 100,000-Yen-a-Month Property: How Much Is Left Over?
From here, let's work through concrete figures. Every amount in the table below is a hypothetical assumption and does not represent the going rate for any actual property. For the property you are actually considering, redo the calculation using the management company's estimate and your property tax assessment statement.
| Item | Monthly amount (all hypothetical) | Assumption used |
| Rental income | +100,000 yen | Assumes full occupancy |
| Property management outsourcing fee | −5,000 yen | Assumed at 5% of rent (varies by contract) |
| Building management fee and repair reserve fund | −10,000 yen | A hypothetical amount assuming a condominium unit |
| Property tax and city planning tax | −6,000 yen | A hypothetical amount, 72,000 yen a year divided into 12 |
| Casualty insurance premium | −1,000 yen | A hypothetical amount, 12,000 yen a year divided into 12 |
| Self-funded reserve for restoration and repairs | −5,000 yen | A hypothetical amount you set aside yourself to cover costs at move-out |
| Amount left after operating costs | +73,000 yen | This is what remains before loan repayment |
| Loan principal and interest repayment | −60,000 yen | A hypothetical amount that varies greatly with your borrowing terms |
| Pre-tax cash flow | +13,000 yen | Cash before income tax and resident tax are deducted |
Under these assumptions, of the 100,000 yen in rent, what is left over is 13,000 yen a month, or 156,000 yen a year. Here we want to check the impact of vacancy. If the unit sits vacant for just one month out of the year, you lose the 100,000 yen in rent, while the only expense that disappears is the 5,000 yen management fee. The net effect is that 95,000 yen vanishes, and the year's take-home amount drops to 61,000 yen. One month of vacancy carries off roughly 60% of the year's cash flow — that is the structure you are working with.
Depreciation does not appear in this cash-flow table. But because it is included in deductible expenses when calculating real estate income, the resulting tax figure diverges from the actual movement of cash. You can end up with "a year the books show a loss but cash is left over," or, just as easily, "a year cash is tight but tax is still due." Note that tax treatment varies according to individual circumstances, so please confirm with a tax accountant or similar professional before acting.
Use the National Rent Level as Your Yardstick
To judge whether a proposed assumed rent is too high, it helps to know the actual figures from official statistics. According to the Ministry of Internal Affairs and Communications' 2023 Housing and Land Survey, the average monthly rent for rented housing (dedicated residential units) was 59,656 yen, up 7.1% from 2018. Per tatami mat, that works out to 3,403 yen.
| Type of rented housing | Monthly rent | Change vs. 2018 |
| All rented housing (dedicated residential units) | 59,656 yen | up 7.1% |
| Public rented housing | 24,961 yen | up 7.6% |
| Urban Renaissance Agency (UR) and public corporation rented housing | 71,831 yen | up 2.8% |
| Privately rented housing (wooden) | 54,409 yen | up 4.5% |
| Privately rented housing (non-wooden) | 68,548 yen | up 7.0% |
The national average is not a figure that directly explains the rent in any specific area. Even so, if the assumed rent significantly exceeds the 68,548-yen average for privately rented non-wooden housing, you need to be able to explain what accounts for the gap — distance from the station, the building's age, or its features. If you are handed a cash-flow plan that says "this works at this rent" without an explanation, set it aside for now.
Weighing the Benefits and Drawbacks of Real Estate Investment as Pairs
You are less likely to misjudge if you understand benefits and drawbacks as pairs rather than as separate lists. That is because most benefits flip straight into risks the moment the condition that makes them work no longer holds. "Leverage works in your favor" is simply the flip side of "the obligation to repay continues."
| Benefit | Condition for it to hold | Risk that appears once the condition no longer holds |
| Borrowing lets you deploy more than your own capital | Rent must cover both loan repayment and operating costs | If rates rise, repayments increase; if a vacancy occurs, you must cover the shortfall from your own funds |
| Group credit life insurance clears the remaining loan balance if something happens to you | You must take out a loan with group credit life insurance attached | The premium equivalent is added to the interest rate, squeezing your monthly cash flow |
| In a year you post a loss, you can offset it against other income such as salary | You must have other income to offset it against | The portion of loan interest corresponding to funds used to acquire the land is excluded from this offset (NTA No.1391). And a loss, to begin with, means your cash is shrinking |
| It remains as a physical asset even as prices rise | Rents and land prices must actually move | As a rule, rent stays fixed during the lease term and does not rise nearly as fast as prices do |
| Because the physical asset remains, its value rarely falls to zero | The building must be kept in usable condition | Converting it to cash takes time, and you may not be able to sell it exactly when you need the money |
The third row is the one most often misunderstood. The claim that "real estate investment reduces your taxes" presupposes that you are running a loss. NTA No.1391 states that a loss on real estate income can be offset against other income, but explicitly excludes the portion of loan interest, included in deductible expenses, that corresponds to funds used to acquire the land. Ordinarily, the loss itself is larger than the tax savings. Tax treatment varies according to individual circumstances, so please confirm with a tax accountant or similar professional before acting.
Leverage Cuts Both Ways, Equally
The leverage mentioned in the first row also becomes clearer once you convert it into actual amounts. Every figure below is hypothetical. Say you add a 15-million-yen loan to 5 million yen of your own capital to acquire a 20-million-yen property. A 5% move in price is 1 million yen. That same 1 million yen amounts to 20% relative to your 5 million yen of own capital. By the same logic that makes the gain large when prices rise, the impact is just as large when they fall. That is what leverage really is.
Repayment works the same way. The larger your loan, the bigger the change in your monthly repayment when the interest rate moves by 0.5 points. That is precisely why the interest-rate stress test discussed later is worth running first if your loan-to-value ratio is high.
Also check the terms of the group credit life insurance mentioned in the second row. The premium equivalent for this coverage is sometimes added on top of the interest rate, which increases your monthly repayment by that amount. Having the coverage is itself reassuring, but as a practical matter you should build your cash-flow calculation using the rate after that addition.
You Cannot Eliminate the Drawbacks, but You Can Plan for Them
On the drawback side, how you spend your time is easy to overlook. Even if you outsource management, it is the owner who decides the scope of restoration work and the leasing terms every time a tenant moves out. Putting off that decision extends the vacancy period, and your annual take-home amount shrinks by that much.
Say it takes two weeks from when you receive notice of a move-out to when you confirm the restoration estimate and set the leasing rent. Those two weeks are added directly to your vacancy days. At a rent of 100,000 yen, that is about 50,000 yen. How fast you decide translates directly into money.
If your cash-flow plan is built on the premise that "vacancies happen," "rates move," and "repairs come due," you will not be caught off guard when they actually occur. You cannot eliminate the drawbacks, but if you convert them into figures in advance, they stay within what you planned for.
What Separates People Who Are Suited to Real Estate Investment from Those Who Are Not
What separates a good fit from a poor one is not the size of your income. It comes down to three things: can you state your goal in numbers, can you absorb unexpected expenses out of your own funds, and can you set aside a few hours a month to make decisions. Use the table below to check which column you fall into.
| Decision axis | Go ahead | Consider with conditions | Hold off for now |
| Purpose | Can state, in yen, how much you want left over each month | Direction is set (e.g., retirement funds), but the amount is not | Only a vague motive of "wanting to hold an asset" |
| Own capital | Emergency living funds remain even after paying incidental costs in cash | Can pay incidental costs, but cash on hand runs thin afterward | Plans to cover even incidental costs through borrowing |
| Borrowing and repayment | Repayment still works even if the rate rises 1.0 point | Works at the current rate, but with little margin | Repayment ratio is already high even at current terms, with no margin |
| Time available | Can spend a few hours a month reading reports and deciding | Hard during busy periods, but can find time otherwise | Cannot be involved at all and wants to leave everything to someone else |
| Risk tolerance | Can cover several months of vacancy from own funds | Can withstand one to two months | Uneasy about making payments in a month with a vacancy |
Even if you match several items under "hold off for now," that does not mean you are unsuited to real estate investment. It only means your sequence is off. If you change your plan — building up your own capital for another year before deciding, or clearing existing debt with a high repayment ratio first — the quality of your judgment on the very same property changes.
A higher income only gives you an advantage on the amount you can borrow. If someone earning 10 million yen a year misjudges a deal, the loss scales up accordingly. Conversely, someone who lines up in the "go ahead" column above can build steadily even starting small. It is not the size of the sums involved but the repeatability of sound judgment that determines the outcome.
That said, we tell anyone who fits the following three profiles clearly that this is not for them: those who plan to convert to cash within a few years, those uneasy about their repayment outlook, and those with no intention of ever looking at reports from their management company. Real estate takes time to convert to cash, repayments will not wait, and running the property is a continuous string of decisions. For those who want to take their time getting ready, INA's free consultation can help you organize where you stand.
How Much Money Do You Need to Start Real Estate Investing?
The own capital you need varies with the property price and financing terms, so there is no single minimum. What you will definitely need cash for are the initial costs incurred separately from the property price itself. Here are the line items.
- Agent's brokerage commission (sometimes unnecessary if you buy directly from the seller)
- Real estate acquisition tax, registration and license tax, and stamp duty on the sale contract
- Judicial scrivener's fee (for registering the transfer of ownership and the mortgage)
- Fire insurance and earthquake insurance premiums
- Prorated settlement for property tax and city planning tax
- Loan arrangement fee and guarantee fee
The key point to remember is that these must be paid in cash, separately from your down payment. If you prepare only the down payment and forget to budget for these initial costs, you will find yourself short of funds right before settlement. You can check the registration and license tax and stamp duty rates on the National Tax Agency's No.7191 registration and license tax rate table. For a fuller breakdown of the amounts involved and how financing works, see How Much Do You Need to Start Investing in Real Estate? A Basic Guide to Funding and Financing for Beginners.
The 7-Step Guide to Getting Started in Real Estate Investing: The "Condition to Clear Before Moving to the Next Stage"
There are plenty of articles laying out the steps for how to start real estate investing, but people stumble not because they don't know the steps. They stumble because they have no standard for judging whether they are ready to move to the next stage. So we have attached a pass condition to each step. Move forward before you meet the condition, and the strain shows up later in the process.
| Step | What to do | Condition to clear before moving on | Where people tend to stumble |
| 1. Set your objective and a numerical target | Decide how many years from now, and how much take-home income per month, you want | You can state your target take-home amount as "X yen per month" | Getting stuck at "to build assets" and being unable to judge whether a property passes or fails |
| 2. Assess your own capital and creditworthiness | Write down the cash you can put in, existing debt, annual income, and years at your current job | You have a rough figure for both the capital you can invest and the amount you can borrow | The plan ends up dipping into your emergency living funds |
| 3. Check supply and demand in the area | Count for yourself the listing inventory and time-to-lease in the area you are considering | You know the number of competing units currently listed and how quickly units get filled after a move-out | Relying solely on the "assumed rent" figure in the seller's materials |
| 4. Compare properties and recheck the cash flow | Calculate the net yield and pre-tax cash flow yourself | Repayment still works even after applying the three-point stress test described later | Comparing on gross yield alone and never looking at operating costs |
| 5. Get financing terms from multiple lenders | Compare the interest rate, loan term, loan amount, and rate type | You obtained terms from at least two banks and compared them side by side | Deciding based only on terms from the single bank you were introduced to |
| 6. Sale contract, statutory disclosure, settlement, and registration | Confirm the contract terms and the property's rights and title before taking possession | Nothing in the statutory pre-contract disclosure remains unclear to you | Signing without understanding something on the spot and only learning the terms later |
| 7. Outsource management and start operating | Sign a management contract and begin leasing and tenant management | You have decided which figures to check in the monthly report | Not opening the report, and being slow to notice vacancies or missed payments |
Steps 1–2: Translate Your Goal into Numbers
The first hurdle is making your objective concrete. If you can say "I want 50,000 yen a month left over," you can hold that against the hypothetical table above and get a rough sense of the property scale you need. On the other hand, if you get stuck at "because I'm worried about retirement," you have no way to judge whether a given property matches your objective. Start looking at properties without a standard to judge by, and the salesperson's pitch becomes your only yardstick.
Once you put your goal in yen, the scale you need comes into view. In the hypothetical table above, a single 100,000-yen-rent unit left 13,000 yen a month. If the same conditions held, that works out to needing roughly four units to reach 50,000 yen a month in take-home income. Having that number early on makes it clear what you should be learning from your first unit.
When assessing your own capital, separate the amount you can invest from your emergency living funds. If you fail to make this distinction and put everything toward the down payment, you may find yourself unable to pay for restoration work at the first move-out, delaying re-listing by two months. This kind of bind is not unusual. Cash on hand is, quite literally, your operating margin.
Assess your creditworthiness at the same time. Write out the balances on your home mortgage, auto loan, card loans, and student loans, and divide your total annual repayment amount by your annual income. The higher this ratio, the smaller the amount you will be able to borrow on an investment loan. In some cases, you will get better terms by clearing your existing debt before applying.
Steps 3–5: Count It Yourself, Calculate It Yourself
You can get a rough sense of the area's supply and demand just by counting, on a rental portal site, how many units matching your candidate property's conditions are currently listed. How many units are listed at the same station, with the same layout, in the same rent range? The more there are, the longer it will take to fill a vacancy when one opens up. Look at the rent actually being advertised, not the assumed rent written in the seller's materials.
Go one step further and check the same search again two weeks later. If a unit that was there last time is still listed, it has not rented at that price. Conversely, in an area where turnover is fast, some vacancy may get filled within a few weeks. Watching the "turnover" of listings, rather than just the "volume," is the check that comes closest to the real feel of local supply and demand. With 4,436,000 vacant units held for rent nationwide, there are few places where you can afford to skip this step.
Recheck your cash flow using net yield, not gross yield. After confirming the formula in Net Yield vs. Gross Yield: The Difference and What to Expect, subtract the management outsourcing fee, building management fee, repair reserve fund, property and city planning tax, and insurance premium. Compare properties without subtracting operating costs, and a condominium unit with a high management fee and repair reserve will look better than it really is.
Approach at least two banks for financing, and you will get a real feel for the range of terms available. Interest rate is not the only thing to compare. Line up four points: loan term, loan amount, rate type (variable or fixed), and the arrangement fee and guarantee fee. The loan term in particular has a direct effect on your monthly repayment. Because the building's remaining statutory useful life can influence how a bank thinks about the term, also keep in mind that older properties tend to be offered shorter loan terms.
Steps 6–7: The Contract Signing, and Designing Your First Month of Operation
The statutory pre-contract disclosure exists precisely so nothing is left unclear. If there is a clause you cannot understand on the spot, it is fine to decide to reconvene another day. You cannot change the terms after settlement, but you can still ask questions before it.
The following items are easy to overlook on an investment property: the boundaries of the land and whether anything encroaches on it; legal restrictions such as under the Building Standards Act; for a condominium unit, whether management fees or the repair reserve are in arrears, and the long-term repair plan; and for a property with a tenant already in place, the terms of the lease you will be taking over and the amount of the security deposit you will be holding. Every one of these becomes your burden after you buy.
Once you take possession, decide up front what you will require the management company to include in its monthly report. Occupancy rate, whether there are any arrears, and the number of inquiries on any unit currently listed. Watching just these three every month can bring problems to light months earlier. We have summarized how to choose a management company in Why Choosing the Right Property Management Company Matters for Real Estate Investment Success, and How to Select One.
What we want to convey across these seven steps is that meeting the pass condition before moving forward is, in the end, faster than simply pushing ahead. A property bought by skipping a condition has its shortfalls surface once you're operating it, and fixing them then costs time and money. Once you have internalized this sequence with your first unit, your judgment on the second unit and beyond becomes remarkably fast.
Numbers to Check Before You Start: Yield, Interest Rates, Supply and Demand, and Price Levels
You can check whether the numbers on a proposed property are out of line with the market using four sets of official, published data: expected yield, the policy interest rate, supply and demand for rental housing, and price levels. Knowing where these stood in 2026 lets you judge for yourself whether the assumptions in a sales presentation are realistic.
Look at Net Yield, Not Gross Yield
Gross yield is annual rental income divided by the property price, and it does not include operating costs. Net yield is calculated after subtracting operating costs such as the management outsourcing fee and property and city planning tax. The gap between the two translates directly into a gap in take-home income, so when comparing properties, use net yield consistently. You can check the formula in Net Yield vs. Gross Yield: The Difference and What to Expect.
For the market-level benchmark, the Japan Real Estate Institute's "54th Real Estate Investor Survey" (as of April 2026) is a useful reference. The expected yields for a whole rental building are as follows. However, respondents to this survey are mainly institutional investors, so the levels differ from the actual market for the small- and mid-sized properties that individuals acquire. Read it not as your own target yield but as "a rough gauge of the minimum line professionals require."
| Survey area | Studio type | Family type |
| Tokyo, Jonan area | 3.6% (down 0.1 point from the previous survey) | 3.7% (down 0.1 point from the previous survey) |
| Sapporo | 4.9% | 5.0% |
| Sendai | 5.0% | 5.0% |
| Yokohama | 4.2% | 4.3% |
| Nagoya | 4.5% | 4.5% |
| Kyoto | 4.6% | 4.6% |
| Osaka | 4.2% | 4.3% |
| Kobe | 4.7% | 4.7% |
| Hiroshima | 5.0% | 5.1% |
| Fukuoka | 4.5% | 4.5% |
The 2026 Interest Rate Environment
At its Monetary Policy Meeting on June 16, 2026, the Bank of Japan decided to guide the uncollateralized overnight call rate to remain around 1.0%. At the same time, it set the rate applied under the complementary deposit facility at 1.0% and the basic loan rate at 1.25%. At its meeting on July 31, this policy was maintained.
What is frightening when rates start moving is that a repayment set up on a variable rate can exceed what you planned for. We cannot say for certain where interest rates will go from here, but unless your cash-flow plan assumes the possibility of a rise, it is not adequate as a basis for judgment. We cover what happens as holding costs rise in What Really Happens to Holding Costs When Interest Rates Rise.
Check the Assumption That "A Tenant Will Be Found" Against Supply and Demand
According to the Ministry of Internal Affairs and Communications' 2023 Housing and Land Survey, the number of vacant homes nationwide reached 9,002,000, an all-time high, and the vacancy rate hit a record 13.8%. Of these, 4,436,000 vacant units are held for rent, accounting for 49.3% of all vacant homes. Limited to vacant units in multi-unit buildings, 78.5% (3,947,000 units) are held for rent.
These figures show that there are places nationwide where rental housing is in surplus. Of course, supply and demand vary greatly by area, so the national figures do not apply directly to the property you are considering. That is exactly why, in Step 3, you need to count the listing inventory with your own eyes.
Where Do Price Levels Currently Stand?
In MLIT's Residential Property Price Index (December 2025, seasonally adjusted, average for 2010 = 100), the nationwide residential composite stands at 148.0, residential land at 119.8, detached houses at 121.9, and condominium units at 225.1. Condominium units alone have risen dramatically. Meanwhile, the 2026 Publicly Announced Land Prices (as of January 1, 2026, across 26,000 points nationwide) show that the all-use average, residential land, and commercial land have all risen for five consecutive years.
When the acquisition price is high, yield falls even for the same rent. We cannot say for certain where prices will go in the future, but if you design your plan without assuming "I can sell for what I paid," you keep your options open at the exit.
Apply the Three-Point Stress Test Before You Decide
A cash-flow table can be made to show a profit simply by lining up favorable assumptions. Only the numbers after you apply stress are usable for making a decision. Apply the following three stresses at the same time and confirm whether your annual cash flow stays positive.
| Stress applied | How to change the calculation | Figures affected |
| Raise the interest rate by 1.0 point | Add 1.0 to the rate used in your repayment simulation | Monthly principal-and-interest repayment and total repayment |
| Lower the occupancy rate by 10 points | Multiply annual rental income by 0.9 | Annual rental income and cash flow |
| Lower the rent by 5% | Recalculate by multiplying assumed rent by 0.95 | Annual income, and the exit price determined by yield |
| Apply all three at once | Produce the annual cash flow with all of the above stacked together | If it is still positive under these conditions, it is usable as a basis for judgment |
If the result turns negative after the three-point stress test, the deciding question is whether you can cover that shortfall out of your own funds every year. The moment you know you cannot, you walk away. Being able to make that call is, in the end, what lets people keep going in this business for the long haul.
Five Things Beginners Must Settle Before They Buy
Before you even get to managing risk once you hold the property, there are issues that can only be settled before the contract. Every one of them is something you cannot redo once you have bought, so check them off one by one before you sign the contract.
| What to check | Why it must be before the contract | How to check it |
| Do not use a home mortgage intended for your own residence to acquire an investment property | The permitted use of funds is fixed by the loan contract, and violating it is a serious problem | Finance an investment property with an investment loan. Tell the lender accurately what it will be used for |
| The rent-reduction, rent-free (immunity) period, and cancellation clauses of a sublease (master lease) contract | You cannot unilaterally change the terms once the contract is signed | Confirm whether a rent-reduction claim is possible, and the length of the rent-free period, in the statutory disclosure given before signing a specified lease contract |
| Whether the management company is registered as a rental housing management business | Registered operators are subject to statutory duties to explain and report | Confirm the registration number issued by the Minister of Land, Infrastructure, Transport and Tourism, and ask about the on-site business manager and the content of periodic reports |
| The level of the repair reserve fund and the timing of any planned major repairs | A special assessment or a reserve-fund increase right after you buy can wreck your cash flow | For a condominium unit, check the long-term repair plan and reserve-fund balance; for a whole building, check the renewal history of the roof, exterior walls, and plumbing |
| Who the buyer will be at exit | Because the buyer pool determines how the price is set | Distinguish whether the property is one an end user (someone who will live there) can buy, or one only investors will buy |
Item two, sublease, is worth understanding as a system in its own right. Under the Rental Housing Management Business Act, MLIT prohibits sublease operators and similar businesses from exaggerated advertising and unfair solicitation. The ministry cites, as a specific example of a prohibited act, soliciting a contract while deliberately failing to explain matters that should be disclosed. What must be disclosed includes the future risk of a rent reduction and the possibility of the sublease operator canceling the contract even during its term. The same applies to the fact that, under the Act on Land and Building Leases, the owner needs justifiable grounds to cancel, and to the owner's cost burden for maintenance, restoration, and major repairs. Failing to explain that there is a rent-free period on the master-lease rent during the first several months after a new building is completed is also cited as an example.
This is not about singling out any particular company as a problem. It means that the "guaranteed rent" mechanism itself requires you to read the terms carefully. In the contract and the statutory disclosure document, check, with your own eyes, at minimum the rent-reduction clause and the rent-free period. Item one is covered in detail in Why You Must Not Use a Home Mortgage to Acquire an Investment Property.
Item three, the management company's registration, gets you an answer simply by asking before you sign. A registered operator is required to explain the content and method of management services in writing before the management contract is signed, and is also required to keep rent and similar funds segregated from its own assets. The moment someone tells you "a verbal explanation is fine," that is a reason to dig deeper.
For item four, repairs, timing matters more than the size of the amount. If a major repair is scheduled for the year after you acquire the property and the reserve fund is insufficient, it comes back to you as the owner in the form of a special assessment or a higher reserve contribution. For a condominium unit, the long-term repair plan and the reserve-fund balance; for a whole building, the renewal history of the roof, exterior walls, and plumbing — these are the documents worth reviewing before you sign.
Three Investment Styles That Are Easy for Beginners to Consider
The three options beginners most often start with are a condominium unit, a detached house, and a small apartment building. The differences are not just about price range. The impact of a vacancy, who has the final say on repairs, and the pool of buyers at exit all differ.
| Point of comparison | Condominium unit | Detached house | Small apartment building |
| Size of initial investment | Smallest of the three | Varies widely by location | Largest of the three |
| Impact of a vacancy | Income drops to zero | Income drops to zero | Rent from the other units continues |
| Who has final say on building-wide repairs | Determined by a resolution of the management association | The owner decides alone | The owner decides alone |
| Fixed monthly costs | Management fee and repair reserve fund apply | No common areas, so fixed costs are small | You arrange cleaning and upkeep of common areas yourself |
| Share of the land | Only a proportional interest, as a right to the site | You own the land outright | You own the land outright |
| Typical tenant profile | Mainly singles and two-person households | Mainly families | Ranges from singles to families depending on the unit |
| Buyer pool at exit | Both investors and end users | Mainly end users | Mainly investors |
| Who it suits | Those who want to start small and learn how to operate | Those who value owning land outright and want to decide on repairs themselves | Those who want to spread vacancy risk and pursue scale |
With a condominium unit, the management association and the management company handle upkeep of the entire building, so the owner's effort stays small. The flip side is that you cannot decide, on your own, the timing of major repairs or an increase in the reserve fund. If the management association votes to raise the reserve fund, your own cash flow changes starting the following month. Understand this as a structure where you trade away control over costs in exchange for less effort. The breakdown of initial costs is covered in Essential Initial Costs and Running Costs of Condominium Investment.
Because you own the land outright with a detached house, the land remains even as the building ages, and this makes it easy to sell to an end user at exit. You can also decide for yourself how far to take repairs. On the other hand, everything from the vegetation on the lot to the plumbing falls within the owner's responsibility to manage. There is no management association to act on your behalf, as there is with a condominium unit. The practical side of running one is summarized in Success Strategies and Benefits of Detached-House Rental Management.
With a small apartment building, rent comes in from multiple units, so a single vacancy does not drop your income to zero. In exchange, you take on responsibility for maintaining the entire building, and your loan amount grows larger too. You arrange the cleaning and lighting of common areas yourself, and renewal of the exterior walls and roof, and you set aside the funds for it yourself. It is a type where you trade away vacancy-risk concentration for a heavier operational load. The mechanics and risks are explained in The Mechanics, Benefits, and Risks of Whole Apartment Building Investment.
There is no ranking of which of the three is superior. Whether you can state, in yen, what happens in a month with a vacancy is the standard for choosing. For a condominium unit or a detached house, income stops entirely with a single vacancy, so the premise is that you can cover that month's repayment out of your own funds.
The buyer pool at exit is another point worth confirming before you choose. If the property is one an end user can buy, its price is anchored to prevailing local market prices. If only investors will buy it, its price is set by yield. In other words, the structure is such that if rent falls, the sale price falls with it. The fact that condominium units stand out at 225.1 on MLIT's Residential Property Price Index can also be read as reflecting that they are an asset both end users and investors can buy.
As a matter of sequence, the realistic path is to learn the operating pattern with a condominium unit or detached house first, then expand into an apartment building. Experiencing, on your first unit, how to set leasing terms and judge restoration work means that adding more units later simply repeats the same decisions. Go for scale without that experience, and you will face multiple decision points all at once.
What to Do After You Buy: Outsourcing Management, Monthly Numbers to Watch, and Tax Basics
There are two things to decide after you take possession: what to have the management company report, and what to gather in preparation for your tax return. Design both of these in your first month, and the operation from there on gets easier.
Get the Explanation Before You Sign the Management Contract
Under the Rental Housing Management Business Act, a rental housing management operator managing 200 units or more is required to register with the Minister of Land, Infrastructure, Transport and Tourism. Registered operators are required to station at least one business manager at each place of business or office. Before a management contract is signed, they are obligated to hand over documents and explain the specific content and method of the management services. They are also required to keep the rent and other funds they manage segregated from their own proprietary assets, and to report regularly to the client on how the work is being carried out.
In other words, as the party outsourcing management, you are entitled to an explanation before the contract and to periodic reports after it. If several months have passed without a report arriving, that itself is a situation worth checking.
Narrow It Down to Six Numbers to Check Every Month
You do not need to read every line of the report. Track just the following six items, and you will notice a change in earning power.
| Item tracked | How to read it | What it tells you |
| Occupancy rate | Occupied units ÷ total units | The foundation of your income. Compare with the same month a year earlier |
| Arrears rate | Amount in arrears ÷ amount billed | Whether tenant screening and collections are working |
| Leasing period | Days from move-out to the next lease signing | Whether your rent and leasing terms match the market |
| Restoration cost | Amount and breakdown per instance | Whether equipment needs replacing, and whether the tenant/owner cost split is reasonable |
| Advertising cost | Amount spent per signed lease | The real cost of closing a lease at that rent |
| Repair cost | Annual cumulative total, and the share that was unplanned | When it is time to switch to planned repairs |
Taxes Start with "Sorting Out Revenue and Expenses"
Real estate income is calculated by subtracting deductible expenses from gross revenue (NTA No.1370). In a year you post a loss, you can offset it against other income, but the portion of loan interest, included in deductible expenses, that corresponds to funds used to acquire the land, is excluded (No.1391, No.2250). The concept of depreciation is set out in No.2100, and how to determine the useful life of a used building is set out in No.5404.
When you sell, the gain is calculated as capital gain on transfer, and the tax rate bracket changes depending on whether you have held the property for more than five years (No.3202, No.3208). There are set rules for counting the acquisition date and the transfer date, so confirming them before you start considering a sale makes it easier to plan.
Preparing for your tax return comes down to one thing: not letting documents pile up. Here is what to gather in your first year: the sale contract and statutory disclosure document, the loan agreement and repayment schedule, the settlement statement for the purchase price, the property tax notice, the fire insurance policy, the management company's annual income and expense report, invoices and receipts for repairs and restoration, and the lease agreement. Once you have all of this together, sorting revenue from expenses becomes almost mechanical.
In the first year especially, you will need to judge whether to treat the incidental costs at acquisition as an expense or to fold them into the acquisition cost. Tax treatment varies according to individual circumstances. Please confirm with a tax accountant or similar professional before acting. On points where judgment can go either way, we too avoid making a call on the spot and check with our retained tax accountant before advising you.
In Summary: How to Start Real Estate Investing Comes Down to "Verifying the Numbers Before You Buy"
People stumble in getting started with real estate investing not because they don't know the steps. They stumble because they move to the next stage without ever calculating for themselves how much of the rent is actually left over. Know what belongs in gross revenue and deductible expenses, apply the three-point stress test, and move forward only once you have met each step's pass condition. Simply keeping to this order changes the quality of your judgment enormously.
We do not think of real estate as a product where the deal ends once it's sold. Long-term operation only works once tenants can keep living there, the owner's asset keeps growing, and the people involved in managing it can keep doing their work with pride. Build your numbers on the premise that you are growing this over time, and you stop choosing on headline yield alone.

Frequently Asked Questions (FAQ)
What is real estate investment?
It is a business of acquiring a property, leasing it to tenants, and earning rental income. The gain realized on sale (capital gain) is also a return, but what beginners should build their foundation on is the monthly rental income (income gain). It differs in character from holding stocks in that the outcome is not decided the moment you buy — decisions about leasing, repairs, and the exit continue for as long as you hold it.
How much money do I need to start real estate investing?
There is no single minimum, since it varies with the property price and financing terms. Separately from the property price, you need cash for the brokerage commission, real estate acquisition tax, registration and license tax, stamp duty, judicial scrivener's fee, fire insurance premium, and prorated property and city planning tax. You can check the rough amounts involved and how financing works in How Much Do You Need to Start Investing in Real Estate? A Basic Guide to Funding and Financing for Beginners.
How much rental income can I expect?
In the Ministry of Internal Affairs and Communications' 2023 Housing and Land Survey, the average monthly rent nationwide for rented housing (dedicated residential units) was 59,656 yen. For privately rented housing, it was 54,409 yen for wooden buildings and 68,548 yen for non-wooden buildings. Note that this is a national average, and your actual take-home amount is what remains after deducting the management outsourcing fee, property and city planning tax, insurance premium, repair costs, and loan repayment.
What should a beginner do first?
The first thing a beginner should do is set their objective in yen. Be able to state, in numbers, "how many years from now, and how much a month I want left over," and then assess the own capital you can put in and the amount you can borrow. Holding off on looking at property listings until you have both of these in hand keeps you from outsourcing your judgment to a sales pitch.
What are the drawbacks of real estate investment?
There are three: converting the asset to cash takes time, a vacancy or a rate increase can worsen your cash flow, and operational decisions never really stop. If, hypothetically, your annual take-home amount is 156,000 yen on 100,000 yen of monthly rent, a single month of vacancy wipes out roughly 60% of it. You cannot eliminate the drawbacks, but knowing the figures in advance keeps them within what you planned for.
Can I buy an investment property with a home mortgage?
You cannot use a home mortgage intended for your own residence to acquire an investment property. The permitted use of funds is fixed by the loan contract. Finance an investment property with an investment loan, and tell your lender accurately what it will be used for. Interest rates and loan terms differ from those of a home mortgage.
