In 2026, investing in a whole-building apartment (一棟マンション, ittō manshon) in Japan means fighting inside a narrow spread: expected yields of 3.6-5.0% against borrowing rates now in the high-1% range. This is a distinctly Japanese asset class with no exact equivalent in the US, UK, or Australian markets, where "multifamily" typically means either a large syndicated apartment complex or a handful of single-family rental units. Japan's ittō manshon sits in between: a single reinforced-concrete (RC) building of roughly 10-30 units that one owner — an individual or a company — holds outright and manages directly, with no condo association and no HOA standing between the owner and the roof. (All JPY figures in this article are converted to USD at an approximate rate of ¥150 = US$1, as of 2026-08-13, for illustrative purposes only; actual rates fluctuate daily.)
What decides whether the investment wins or loses is not the yield printed on the sales flyer, but the debt-service ratio set by your down payment and loan term, and how much you can set aside every year for building repairs. This article is written for business owners and individual investors — in Japan or abroad — considering the acquisition of a roughly ¥100 million (approx. USD 667,000) whole-building apartment, whether through a company or personally. It answers three questions with real numbers grounded in Japanese government statistics and tax rates: how large a down payment do you actually need, what percentage of the purchase price do upfront costs really consume, and at what yield does the deal actually pencil out once every cost has been subtracted?
Key takeaways from this article
- As of April 2026, expected yields for whole-building rental housing are 3.6% in Tokyo's Jōnan area, 4.2% in Osaka, and 5.0% in Sendai and Hiroshima (Japan Real Estate Institute, 54th Real Estate Investor Survey). These figures use a different definition than the "7-8% gross yield" numbers commonly advertised on listing sites.
- Borrowing costs have risen: the average contracted interest rate on new long-term loans from Japanese domestic banks climbed from 1.378% in August 2025 to 1.944% in June 2026. The Bank of Japan's policy rate (the target for the uncollateralized overnight call rate) sits at around 1.0%.
- For the model property used throughout this article — a ¥100 million (approx. USD 667,000) building — upfront costs total roughly ¥6.49 million (approx. USD 43,300), or 6.5% of the price. Add the ¥4 million (approx. USD 26,700) consumption tax charged on the building portion, and the cash required at closing rises to about ¥10.49 million (approx. USD 69,900), or 10.5% of the price.
- The right down payment isn't a fixed percentage — it's whatever your Debt Service Coverage Ratio (DSCR) requires. At a 7.0% gross yield and a 20-year loan term, reaching a DSCR of 1.3 requires a down payment of about 39%; stretch the loan to 30 years and 16% is enough. Loan term moves the number more than the down payment does.
- Funding repairs at the level recommended by the Ministry of Land, Infrastructure, Transport and Tourism (国土交通省, MLIT) guideline costs about ¥1.61 million (approx. USD 10,700) a year for a 400 sqm building. Factor that in, and the NOI yield drops from 4.8% to 3.2%. Whether you see that gap before you buy — or discover it ten years later — is what separates a durable investment from a disappointing one.
What Is Whole-Building Apartment Investing? Comparing Condo Units and Wood-Frame Buildings by the Numbers
Whole-building apartment investing (一棟マンション投資, ittō manshon tōshi) means acquiring an entire multi-unit residential building — typically reinforced-concrete (RC) construction — along with the land beneath it, and collecting rent from multiple units under a single title. This differs from buying a single condominium unit (区分マンション, kubun manshon), Japan's rough equivalent of a US condo or a UK leasehold flat. The two biggest differences from unit-by-unit investing are how a single vacancy hits your income, and who is responsible for saving up for major repairs. In a condo building, a management association (管理組合, kanri kumiai) — comparable to a US homeowners' association (HOA) or the management company attached to a UK block of flats — collects a mandatory reserve fund from every unit owner. In a whole building, there is no such association: the owner alone is responsible for setting that money aside. Unlike a US homeowners' association (HOA) or a UK block's management company, which quietly cover roof and elevator replacement through mandatory dues, a whole-building owner in Japan has no such buffer standing between them and a failed roof — you are your own HOA, for better and for worse.
Condo Units vs. Wood-Frame Apartment Buildings vs. Used and New RC Buildings: A Side-by-Side Comparison
Qualitative comparisons like "the yield is higher" or "management is easier" aren't decision-grade. The table below lines up the concrete numbers and legal frameworks instead: statutory useful life, the depreciation period you can actually claim, and who is responsible for funding major repairs.
| Item | Condo Unit | Whole Wood-Frame Apartment Building | Used Whole RC Building (15 Years Old) | New Whole RC Building |
|---|---|---|---|---|
| Statutory useful life (residential use) | 47 years (for RC construction) | 22 years | 47 years | 47 years |
| Depreciation period when acquired used (simplified method) | Shortened based on building age | 10 years if 15 years old | 35 years | 47 years (simplified method not applicable) |
| Construction cost benchmark (at time of new construction) | N/A (acquired used) | N/A (acquired used) | N/A (acquired used) | RC construction: ¥314,300/sqm (approx. USD 2,095/sqm), FY2023 (Reiwa 5) |
| Expected yield for whole-building rental housing | Not surveyed | Not surveyed | Studio type: 3.6-5.0% (varies by city) | Same as at left (new builds tend toward the lower end) |
| Income impact of one vacant unit | 100% (rental income drops to zero) | 1 ÷ number of units | 1 ÷ number of units | 1 ÷ number of units |
| Funding for major repairs | Collected by the management association as a reserve fund | Owner bears 100% out of pocket | Owner bears 100% out of pocket | Owner bears 100% out of pocket (though little is due in the near term) |
| Consumption tax on the building portion | Taxable if the seller is a taxable business | Same as at left | Same as at left | Taxable |
Pay particular attention to the depreciation period. A 15-year-old wood-frame building qualifies for just 10 years under the simplified method — you can expense the building quickly, but once depreciation runs out, taxable income jumps sharply. A used RC building's 35-year period, by contrast, spreads a thinner tax benefit over a much longer window — and that longer window happens to line up well with the loan terms banks are willing to offer.
Gross Yield, Net Yield, and Expected Yield (NOI Yield): Three Numbers That Aren't Interchangeable
These three yield figures use different formulas, so comparing them directly is meaningless. Confusing one for another is the single most common mistake investors make when evaluating a whole building.
- Gross yield (表面利回り, hyōmen rimawari): Annual rent assuming full occupancy ÷ purchase price. It subtracts neither operating expenses nor vacancy loss. This is almost always the number printed on a Japanese sales flyer — the equivalent of a US listing's advertised "cap rate" before you've checked whether it's actually a cap rate at all.
- Net yield (実質利回り, jisshitsu rimawari): (Annual rental income − operating expenses) ÷ (purchase price + upfront costs). This gets closer to your real take-home return, but which expenses a seller includes in the calculation varies from listing to listing, so two "net yield" figures from two different sellers are not always comparable.
- Expected yield / NOI yield (期待利回り, kitai rimawari): The yield, based on Net Operating Income (NOI), that investors require when acquiring a property. This is the figure published in the Japan Real Estate Institute's survey — the closest Japanese equivalent to the cap rate used in institutional US and UK commercial real estate underwriting.
It's entirely normal for the same property to show a 7.0% gross yield and a 4.8% NOI yield — a gap of more than two full points. We break down when to use which metric in more detail in Gross Yield vs. Net Yield in Real Estate Investment: What to Watch For When Choosing a Property.
2026 Yield Benchmarks for Whole-Building Apartments: City-by-City Primary Data
As of April 2026, expected yields for whole-building rental housing (studio-type units) range from a low of 3.6% in Tokyo's Jōnan area to a high of 5.0% in Sendai and Hiroshima. If you come across a whole RC building in the greater Tokyo metro area advertised above 5%, the natural first assumption should be that something about its location, age, or occupancy explains the premium — not that you've found a hidden bargain.
Expected Yields for Whole-Building Rental Housing by City (as of April 2026)
| City / District | Studio Type | Family Type |
|---|---|---|
| Tokyo (Jōnan) | 3.6% (down 0.1 pt from the previous survey) | 3.7% |
| Yokohama | 4.2% | 4.3% |
| Osaka | 4.2% | 4.3% |
| Nagoya | 4.5% | 4.5% |
| Fukuoka | 4.5% | 4.5% |
| Kyoto | 4.6% | 4.6% |
| Kobe | 4.7% | 4.7% |
| Sapporo | 4.9% | 5.0% |
| Sendai | 5.0% | 5.0% |
| Hiroshima | 5.0% | 5.1% |
Every figure in this table is an NOI-based expected yield, not a gross yield. Even within the same city, actual transaction yields move with distance to the station, building age, and floor area per unit. Treat this table as a floor — the minimum level investors in that city are demanding — rather than a number you should expect to see quoted on any specific listing.
Three Market Indicators: Land Prices, the Price Index, and Rental Housing Starts
Behind the decline in expected yields lie two forces: rising acquisition prices and shrinking supply. Three official government statistics confirm both.
| Indicator | Latest Figure | Interpretation |
|---|---|---|
| 2026 Official Land Price Publication (地価公示, as of January 1, 2026) | National average, all uses: +2.8% / residential land: +2.1% / commercial land: +4.3% (fifth consecutive year of increase for all three) | Land acquisition costs keep rising; at the same rent, yield falls |
| Real Estate Price Index (December 2025, seasonally adjusted, 2010 average = 100) | Residential composite: 148.0 / Condominium units: 225.1 / Commercial-use apartment buildings (whole buildings), Q4 2025: 176.1 | Condo-unit prices have risen far faster than housing overall, and that has pulled up whole-building acquisition prices too |
| Construction Starts Statistics (full-year 2025) | New housing starts: 740,667 units (down 6.5% y/y); of which rental housing: 324,991 units (down 5.0% y/y, third consecutive year of decline) | New rental supply is being squeezed, which can be a tailwind for occupancy at existing properties |
Why the "7-8% Yield" Figures You See Online Don't Match This Data
There are three reasons for the gap. First, most listing materials and property portals quote gross yield, which subtracts neither operating expenses nor vacancy loss. Second, expected yield is the level investors demand at the top of the market — older buildings, those far from a station, and regional properties do trade at gross yields of 7-9% or more in the actual market. Third, "whole-building apartment" is not one homogeneous asset class: a newer RC building in central Tokyo and a 30-year-old RC building in a regional city are fundamentally different investment propositions, even though both fit the same label — much as a newly built multifamily property in Manhattan and a 1990s garden apartment complex in a secondary Midwest market are both technically "apartment buildings," but nothing else about them is comparable.
In practice, use gross yield only as an initial screening cutoff, and make the actual investment decision on NOI and DSCR. From here, we'll set up a single model property and trace, with real numbers, exactly how far a 7.0% gross yield gets whittled down.
The Real Cost of Owning a Whole-Building Apartment: Breaking Down Upfront Costs in Actual Yen
Let's start with the conclusion. For a whole RC building priced at ¥100 million (approx. USD 667,000), upfront costs run about ¥6.49 million (approx. USD 43,300) — 6.5% of the price. Add the ¥4 million (approx. USD 26,700) consumption tax charged on the building portion, and the cash that moves between signing and closing reaches roughly ¥10.49 million (approx. USD 69,900), or 10.5% of the price. For international investors used to US closing costs running 2-5% of price, or the UK's Stamp Duty Land Tax structure, this can come as a genuine surprise — Japan's transaction friction on a whole-building purchase is meaningfully higher, and the building-portion consumption tax in particular has no direct analog in most Western residential transactions.
Assumptions for the Model Property
The same model property is used throughout this article. Its assumptions are disclosed up front so every later calculation can be traced back to them.
- Structure and age: RC construction, 15 years old. Total floor area 400 sqm, 10 units total (single-occupant type).
- Purchase price: ¥100 million (approx. USD 667,000) — land ¥60 million (approx. USD 400,000) / building ¥40 million (approx. USD 267,000) — plus ¥4 million (approx. USD 26,700) consumption tax on the building portion = total cash outlay of ¥104 million (approx. USD 693,000).
- Assumed full-occupancy annual income: ¥58,000/month (approx. USD 387) × 10 units × 12 months = ¥6.96 million (approx. USD 46,400), rounded to ¥7 million (approx. USD 46,700). Gross yield 7.0% (based on the ¥100 million pre-tax price).
- Assumed fixed-asset tax assessed value: land ¥42 million (approx. USD 280,000) / building ¥20 million (approx. USD 133,300).
- Financing: loan of ¥83.2 million (approx. USD 554,700) (20% down payment), interest rate 1.944%, 20-year term, equal principal-and-interest repayment.
Fixed-asset tax assessed value varies by property. When evaluating a real listing, obtain the fixed-asset tax statement (固定資産税課税明細書) or a certificate of assessed value (評価証明書) from the seller and replace this figure with the actual number for that property.
Breakdown and Total of Upfront Costs
| Item | Calculation | Amount |
|---|---|---|
| Registration and license tax (land, transfer of ownership) | ¥42 million × 1.5% | ¥630,000 (approx. USD 4,200) |
| Registration and license tax (building, transfer of ownership) | ¥20 million × 2.0% | ¥400,000 (approx. USD 2,670) |
| Registration and license tax (mortgage registration) | ¥83.2 million × 0.4% | ¥333,000 (approx. USD 2,220) |
| Real estate acquisition tax (land, residential lot) | ¥42 million × 1/2 × 3% | ¥630,000 (approx. USD 4,200) |
| Real estate acquisition tax (building, residential) | ¥20 million × 3% | ¥600,000 (approx. USD 4,000) |
| Stamp duty (sale and purchase agreement) | Stated amount ¥100 million (over ¥50 million, up to ¥100 million bracket) | ¥30,000 (approx. USD 200) |
| Brokerage commission | (¥100 million × 3% + ¥60,000) × 1.1 | ¥3.366 million (approx. USD 22,440) |
| Judicial scrivener fee, fire insurance premium, etc. (placeholder) | Finalized by quote | ¥500,000 (approx. USD 3,330) |
| Total upfront costs | 6.5% of the ¥100 million purchase price | ¥6.489 million (approx. USD 43,260) |
| (Reference) Consumption tax on the building portion | ¥40 million × 10% | ¥4 million (approx. USD 26,670) |
| Total upfront costs + building consumption tax | 10.5% of the ¥100 million purchase price | ¥10.489 million (approx. USD 69,930) |
Three points that are easy to overlook in practice are worth adding here.
First, the stated amount used for stamp-duty purposes depends on how consumption tax is written on the contract. If the consumption tax amount is itemized separately on the agreement, stamp duty is assessed on the pre-tax ¥100 million, landing at ¥30,000. If it is not itemized, the assessed amount becomes ¥104 million, pushing the transaction into the "over ¥100 million, up to ¥500 million" bracket at ¥60,000 (NTA No. 7124). This is a detail worth confirming while the contract is still in draft form — the Japanese equivalent of double-checking how VAT is itemized on a UK or EU sale-and-purchase agreement before signing.
Second, the brokerage commission is calculated on the pre-tax base price. For sale prices above ¥4 million, the ceiling is "price × 3% + ¥60,000 + consumption tax." This is a statutory maximum set by government notice, not a fixed or mandatory fee — much like a US real estate commission being technically negotiable even though a de facto standard rate persists in practice.
Third, the ¥4 million (approx. USD 26,700) consumption tax on the building portion is, in principle, not eligible for input tax credit when the acquisition is of a residential rental building (NTA No. 6491). If you build your financing plan around an assumption that this amount will later be refunded, you can find yourself short of cash at closing. We recommend working through this with a tax accountant ahead of time, alongside our related article Real Estate Acquisition Tax Reduction Measures and the Refund Application Procedure.
Tax Reduction Measures Available in 2026, and Their Expiry Dates
Every tax rate in the table above assumes a time-limited reduction is currently in effect. Once these measures expire, rates revert to the standard rate, and upfront costs rise on the same property.
| Measure | Reduced Rate | Standard Rate | Expiry |
|---|---|---|---|
| Registration and license tax (land ownership transfer registration) | 1.5% | 2.0% | Through March 31, 2029 (extended by three years) |
| Real estate acquisition tax (land and residential building rate) | 3% | 4% | Through March 31, 2027 |
| Real estate acquisition tax (taxable base for residential land, etc.) | 1/2 of assessed value | Full assessed value | For acquisitions through March 31, 2027 |
| Stamp duty (real estate transfer agreement) | Over ¥50M-¥100M: ¥30,000 / Over ¥100M-¥500M: ¥60,000 | ¥60,000 / ¥100,000 respectively | For agreements executed through March 31, 2027 |
Running Costs and NOI: How Far Does a 7.0% Gross Yield Actually Get Cut Down?
Here is the model property's annual income statement, subtracted line by line from the top. This is the real substance of whole-building investing.
| Item | Annual Amount | Notes |
|---|---|---|
| Full-occupancy assumed income | ¥7 million (approx. USD 46,670) | Gross yield 7.0% |
| Vacancy and delinquency loss (5%) | −¥350,000 (approx. −USD 2,330) | Assumed vacancy rate is set using the statistics discussed later in this article |
| Effective gross income | ¥6.65 million (approx. USD 44,330) | |
| Property management fee (5% of effective gross income) | −¥333,000 (approx. −USD 2,220) | Confirm the fee rate and scope of services before signing |
| Common-area utilities, cleaning, statutory inspections | −¥400,000 (approx. −USD 2,670) | Water tank, fire safety equipment, etc. |
| Fixed asset tax and city planning tax | −¥480,000 (approx. −USD 3,200) | Assumes the residential land special exception applies |
| Property and casualty insurance | −¥150,000 (approx. −USD 1,000) | Fire, earthquake, and liability coverage |
| Unit turnover restoration and minor repairs | −¥300,000 (approx. −USD 2,000) | |
| NOI (Net Operating Income) | ¥4.987 million (approx. USD 33,250) | NOI yield 4.8% (based on the ¥104 million acquisition price) |
| (Separate line) Reserve for large-scale repairs | −¥1.608 million (approx. −USD 10,720) | MLIT guideline benchmark: ¥335/sqm/month × 400 sqm × 12 months |
| Residual after repair reserve | ¥3.379 million (approx. USD 22,530) | 3.2% of the acquisition price |
A 7.0% gross yield becomes 4.8% at the NOI level, and 3.2% once the repair reserve is funded. That this lands close to the Japan Real Estate Institute's expected-yield range of 3.6-5.0% is not a coincidence. The number professional investors actually look at is the one left standing after all of these cuts. For a US investor accustomed to running a quick back-of-envelope cap rate off the gross rent roll, this three-step waterfall — gross yield, then NOI yield, then post-reserve yield — is the Japanese-market discipline worth adopting before making an offer.
How Much Down Payment Do You Actually Need? A Simulation for the 1.9% Interest Rate Era
The answer to "how much down payment" is not "20%." The required amount swings dramatically with loan term and interest rate, so the practical approach is to work backward from DSCR (Debt Service Coverage Ratio: annual NOI ÷ annual principal-and-interest payments). The conclusion first: on the model property, a 20-year loan term requires roughly 39% down to hit a DSCR of 1.3, while a 30-year term needs only about 16%. US investors used to conventional multifamily lending, where DSCR requirements of 1.20-1.25 are standard and 25-30 year amortizations are common, will find Japan's DSCR discipline familiar in spirit. Compared to that US market, though, the interest-rate and yield environment it operates in is very different — spreads are far thinner, and loan terms are generally shorter.
Borrowing Costs in 2026
| Indicator | Level | As Of |
|---|---|---|
| Uncollateralized overnight call rate target | Approx. 1.0% | Decided June 16, 2026, effective June 17 (maintained at the July 31 meeting) |
| Complementary deposit facility interest rate | 1.0% | Decided June 16, 2026 |
| Basic loan rate (Bank of Japan lending rate) | 1.25% | Same as above |
| Domestic banks, average contracted rate on new loans (long-term) | 1.378% | August 2025 |
| Same | 1.530% | December 2025 |
| Same | 1.885% | March 2026 |
| Same | 1.944% | June 2026 |
| Domestic banks, average contracted rate on new loans (short-term) | 1.452% | June 2026 |
| Domestic banks, average contracted rate on new loans (all terms combined) | 1.767% | June 2026 |
The long-term rate has risen more than half a point in ten months. In this environment, the right question is not "what's the rate at purchase" but "can this deal survive if the rate keeps rising." We discuss asset strategy in a rising-rate environment further in Asset Strategy in a "World With Interest Rates" and How to Respond to a Shrinking Yield Gap. For investors used to a decade of near-zero JPY borrowing costs — or coming from the US and European markets where central banks began raising rates years earlier — this is Japan finally, belatedly, joining a global rate-normalization cycle most other developed markets have already been through, and the yield-gap compression it triggers is a genuinely new dynamic for the Japanese real estate market.
Comparing 0% / 10% / 20% / 30% Down Payments (20-Year Term, 1.944% Interest Rate)
| Down Payment % | Down Payment | Loan Amount | Total Cash Invested (down payment + ¥6.49M upfront costs) | Annual Debt Service | NOI | Annual Cash Flow | DSCR | Cash-on-Cash Return (CCR) |
|---|---|---|---|---|---|---|---|---|
| 0% | ¥0 | ¥104M (approx. USD 693,300) | ¥6.49M (approx. USD 43,260) | ¥6.28M (approx. USD 41,870) | ¥4.987M (approx. USD 33,250) | −¥1.293M (approx. −USD 8,620) | 0.79 | −19.9% |
| 10% | ¥10.4M (approx. USD 69,330) | ¥93.6M (approx. USD 624,000) | ¥16.89M (approx. USD 112,600) | ¥5.652M (approx. USD 37,680) | ¥4.987M (approx. USD 33,250) | −¥665,000 (approx. −USD 4,430) | 0.88 | −3.9% |
| 20% | ¥20.8M (approx. USD 138,670) | ¥83.2M (approx. USD 554,670) | ¥27.29M (approx. USD 181,930) | ¥5.024M (approx. USD 33,490) | ¥4.987M (approx. USD 33,250) | −¥37,000 (approx. −USD 250) | 0.99 | −0.1% |
| 30% | ¥31.2M (approx. USD 208,000) | ¥72.8M (approx. USD 485,330) | ¥37.69M (approx. USD 251,270) | ¥4.396M (approx. USD 29,310) | ¥4.987M (approx. USD 33,250) | +¥591,000 (approx. +USD 3,940) | 1.13 | +1.6% |
At a 20-year term, even putting 30% down keeps DSCR at just 1.13, and once the ¥1.61 million (approx. USD 10,720) repair reserve is layered on top, the property flips into a cash-flow deficit. Buying a 7.0%-gross-yield property on a 20-year loan with little to no down payment simply does not work at 2026 interest rates. This is worth internalizing before you view properties: the "low-money-down" leveraged-multifamily playbook familiar to some US investors does not translate directly to Japan's current whole-building market.
The Same Simulation With a +1.0-Point Rate Increase (20-Year Term, 2.944% Interest Rate)
| Down Payment % | Loan Amount | Annual Debt Service | Annual Cash Flow | DSCR | Cash-on-Cash Return (CCR) |
|---|---|---|---|---|---|
| 0% | ¥104M (approx. USD 693,300) | ¥6.886M (approx. USD 45,910) | −¥1.899M (approx. −USD 12,660) | 0.72 | −29.3% |
| 10% | ¥93.6M (approx. USD 624,000) | ¥6.198M (approx. USD 41,320) | −¥1.211M (approx. −USD 8,070) | 0.80 | −7.2% |
| 20% | ¥83.2M (approx. USD 554,670) | ¥5.509M (approx. USD 36,730) | −¥522,000 (approx. −USD 3,480) | 0.91 | −1.9% |
| 30% | ¥72.8M (approx. USD 485,330) | ¥4.821M (approx. USD 32,140) | +¥166,000 (approx. +USD 1,110) | 1.03 | +0.4% |
A one-point rate increase alone adds about ¥480,000 (approx. USD 3,200) a year to debt service at 20% down, widening the cash-flow deficit from ¥37,000 to ¥522,000. Even at 30% down, what's left over is only ¥166,000 (approx. USD 1,110) a year — nowhere near the ¥1.61 million repair reserve the property needs. If you borrow on a variable rate, the prudent approach is to assume this right-hand column could be your own reality a few years from now, and keep enough cash in reserve to survive it. Variable-rate borrowers coming from the US, where 30-year fixed-rate mortgages are the cultural default even in commercial contexts, should note that Japanese bank loans on whole-building properties are far more commonly variable-rate or short-fixed-period, which is exactly why this kind of stress test is a standard part of Japanese underwriting rather than an optional exercise.
Alternatives to a Larger Down Payment: Loan Term, Prepayment, and Interest Rate Type
A larger down payment is not the only lever for improving DSCR. Here is how the required down payment changes on the same model property when other variables move instead.
| Loan Term | Down Payment Needed for DSCR 1.3 at 1.944% | Down Payment Needed for DSCR 1.3 at 2.944% |
|---|---|---|
| 20 years | Approx. ¥40.48M (39%) (approx. USD 269,870) | Approx. ¥46.07M (44%) (approx. USD 307,130) |
| 25 years | Approx. ¥28.09M (27%) (approx. USD 187,270) | Approx. ¥36.17M (35%) (approx. USD 241,130) |
| 30 years | Approx. ¥16.85M (16%) (approx. USD 112,330) | Approx. ¥27.63M (27%) (approx. USD 184,200) |
Stretching the loan term from 20 to 30 years cuts the required down payment from about ¥40.48 million to about ¥16.85 million — a reduction of ¥23.63 million (approx. USD 157,530). The headline of this table is that loan term moves the required down payment more than the down-payment ratio itself does. However, a 15-year-old RC building has only 32 years of remaining statutory useful life, so whether a bank will actually extend a 30-year loan depends on that lender's specific appraisal methodology. Asking a lender directly "how many years can you lend against a building this age" before you commit to evaluating a specific property will save you from a great deal of wasted due diligence.
Two more options are worth keeping in mind. One is prepayment (繰上返済, kuriage hensai): a "term-shortening" prepayment reduces total interest paid over the life of the loan, while a "payment-reducing" prepayment improves your near-term DSCR immediately. Because the two serve different goals, the payment-reducing type is the more defensive choice in a rising-rate environment. The other is interest rate type: a fixed rate starts higher than a variable rate, but it effectively neutralizes the "+1.0%" stress-test table above. Choosing fixed is a decision to pay a rate-spread cost in exchange for buying certainty in your cash flow — conceptually similar to a US borrower paying up for a 30-year fixed mortgage instead of an adjustable-rate loan, except that in Japan's whole-building lending market, long-term fixed rates are far less commonly offered, which is exactly why this trade-off deserves deliberate attention rather than being assumed as the default choice.
Depreciation and Tax Effects: Calculating Depreciation on a Whole RC Building
Depreciation on a whole RC building comes down to two variables: how much of the purchase price is allocated to the building, and over how many years you can write it off. For the model property (building value ¥40 million, 15 years old), annual depreciation is ¥1.16 million (approx. USD 7,730); the same building value if newly built would be only ¥880,000 (approx. USD 5,870) a year.
Allocating Price Between Land and Building: When the Contract Doesn't State a Building Price
When a sale-and-purchase agreement doesn't state a separate building price, you need a defensible basis for allocating the total between land and building. In practice, the most commonly used tool is the National Tax Agency's "Standard Building Construction Cost Table" (建物の標準的な建築価額表), published in the NTA's annual tax-return filing guide. It provides a per-square-meter unit cost by structure type and construction year, derived by dividing planned construction spending from the government's construction-starts statistics by floor area.
| Construction Year | Reinforced-Concrete Unit Cost (per sqm) |
|---|---|
| Heisei 27 (2015) | ¥240,200 (approx. USD 1,600) |
| Heisei 28 (2016) | ¥254,200 (approx. USD 1,695) |
| Heisei 29 (2017) | ¥265,500 (approx. USD 1,770) |
| Heisei 30 (2018) | ¥263,100 (approx. USD 1,754) |
| Reiwa 1 (2019) | ¥285,600 (approx. USD 1,904) |
| Reiwa 2 (2020) | ¥276,900 (approx. USD 1,846) |
| Reiwa 3 (2021) | ¥288,200 (approx. USD 1,921) |
| Reiwa 4 (2022) | ¥277,500 (approx. USD 1,850) |
| Reiwa 5 (2023) | ¥314,300 (approx. USD 2,095) |
This table also carries an important signal for readers considering new construction instead. At the 2023 RC unit cost of ¥314,300/sqm, building a new 400 sqm structure costs about ¥125.72 million (approx. USD 838,100) for the building alone. Add land, and the total climbs further — meaning that with the same ¥100 million budget, new construction cannot buy you a building the same size as the model property used in this article. "New-build apartment investing" and "used whole RC building" are not comparable strategies at the same budget.
Annual Depreciation: New Construction (47 Years) vs. a 15-Year-Old Used Building (Simplified Method, 35 Years)
Useful life for new construction is the statutory useful life; for used assets, it's calculated under the "simplified method" (簡便法, kanben-hō). The rule: for an asset where part of its statutory useful life has already elapsed, useful life = (statutory useful life − years elapsed) + (years elapsed × 20%); for an asset that has fully exceeded its statutory useful life, useful life = statutory useful life × 20% (rounding down any fraction of a year).
| Case | Useful-Life Calculation | Years | Straight-Line Depreciation Rate | Annual Depreciation on a ¥40M Building |
|---|---|---|---|---|
| New RC (residential) | Statutory useful life | 47 years | 0.022 | ¥880,000 (approx. USD 5,870) |
| Used RC, 15 years old | (47 − 15) + 15 × 0.2 = 35 | 35 years | 0.029 | ¥1.16 million (approx. USD 7,730) |
| Used heavy-gauge steel, 15 years old (34-year statutory life) | (34 − 15) + 15 × 0.2 = 22 | 22 years | 0.046 | ¥1.84 million (approx. USD 12,270) |
| Used wood-frame, 15 years old (22-year statutory life) | (22 − 15) + 15 × 0.2 = 10 | 10 years | 0.100 | ¥4 million (approx. USD 26,670) |
Annual depreciation on the model property (15-year-old RC) is ¥1.16 million (approx. USD 7,730). At an assumed 30% effective corporate tax rate, that translates into roughly ¥350,000 (approx. USD 2,330) in tax savings a year. That looks small next to the wood-frame building's ¥4 million, but the wood-frame building's depreciation runs out after just 10 years, and taxable income jumps sharply starting in year 11. Depreciation doesn't eliminate tax — it defers it. Unlike US MACRS depreciation, which applies a flat 27.5-year schedule to residential rental property regardless of the building's age at acquisition, Japan's system ties the depreciation period directly to construction material and building age: the same building type can carry a dramatically different depreciation schedule purely because of when and how it was built.

Corporate Ownership and Inheritance Tax Valuation: The Tenanted-Land and Rental-Building Discount
One motivation for a business owner to hold a whole building is compressing the inheritance-tax valuation of the underlying assets. Under National Tax Agency rules, the valuation of "tenanted land" (貸家建付地, kashiya-tsuke-chi — land on which the owner has built a rental structure) is calculated using the formula below. This category of valuation discount has no direct equivalent in US estate tax or UK inheritance tax planning, where real property is generally valued closer to fair market value regardless of tenancy status — for internationally minded readers, it is one of the more distinctly Japanese features of holding rental real estate through a company or as an individual near retirement.
- Value of tenanted land = value as owner-occupied land − (value as owner-occupied land × leasehold interest ratio × tenant's leasehold interest ratio × occupancy ratio)
- Occupancy ratio = total floor area of currently leased independent units ÷ total floor area of all independent units (a unit that is only temporarily vacant at the tax assessment date may, in some cases, still be treated as leased)
The leasehold interest ratio for a given plot is found on that area's official roadside land price map (路線価図, rosenka-zu). If we assume a leasehold interest ratio of 60%, a tenant's leasehold interest ratio of 30%, and full 100% occupancy, the model property's ¥60 million (approx. USD 400,000) land value is reduced by "¥60 million × 60% × 30% × 100% = ¥10.8 million (approx. USD 72,000)," bringing the assessed value down to ¥49.2 million (approx. USD 328,000). The building portion is also eligible for a separate valuation discount as a rental structure.
The detail most easily overlooked here is the occupancy ratio. Persistent vacancy pulls the occupancy ratio down, which shrinks the valuation discount along with it. Whole-building ownership as an inheritance-planning tool only works if occupancy is maintained. The moment tax savings becomes the primary objective and day-to-day operations get deprioritized as a result, the strategy tends to unravel — an ordering mistake worth actively guarding against.
Repair Planning: Whole-Building Owners Must Fund Their Own Repair Reserve
The single biggest difference between condo-unit and whole-building ownership is who funds major repairs. A whole building has no management association, so the owner funds the reserve personally. For the 400 sqm model property, following the MLIT guideline benchmark means setting aside roughly ¥1.61 million (approx. USD 10,720) a year.
MLIT Guideline Repair Cycles
You'll often hear a rule of thumb like "repaint the exterior walls every 10 years," but the actual cycle recommended by MLIT's "Guideline for Preparing Long-Term Repair Plans" (revised June 2024) is more nuanced, as shown below.
| Component / Work | Example Repair Cycle |
|---|---|
| Common temporary scaffolding | 12-15 years |
| Rooftop waterproofing (protective type) | Repair: 12-15 years / Full removal and replacement: 24-30 years |
| Exterior wall coating (weather-exposed surfaces) | Repaint: 12-15 years / Strip and repaint: 24-30 years |
| Sealant / caulking | Full replacement: 12-15 years |
| Metal-component painting | 5-7 years |
| Water supply piping | Relining: 19-23 years / Full replacement: 30-40 years |
| Drainage piping | Relining: 19-23 years / Full replacement: 30-40 years |
| Water supply pump | Repair: 5-8 years / Replacement: 14-18 years |
| Elevator | Repair: 12-15 years / Replacement: 26-30 years |
| Exterior grounds / landscaping | 24-28 years |
A 15-year-old building at acquisition is right at the age where exterior wall repainting, rooftop waterproofing repair, sealant replacement, and elevator repair all tend to cluster within a few years of purchase. Whether you can confirm, before you buy, exactly what has already been done and what hasn't — from drawings and maintenance records — is what genuinely determines whether this investment succeeds. A seller who cannot produce that maintenance history is, in itself, a red flag worth treating as risk information.
Repair Reserve Benchmarks and the Annual Amount Required
| Building Height / Total Floor Area | Average Benchmark (per sqm/month) | Range Covering Two-Thirds of Cases |
|---|---|---|
| Under 20 stories / under 5,000 sqm | ¥335 (approx. USD 2.23) | ¥235-430 (approx. USD 1.57-2.87) |
| Under 20 stories / 5,000-10,000 sqm | ¥252 (approx. USD 1.68) | ¥170-320 (approx. USD 1.13-2.13) |
| Under 20 stories / 10,000-20,000 sqm | ¥271 (approx. USD 1.81) | ¥200-330 (approx. USD 1.33-2.20) |
| Under 20 stories / 20,000 sqm or more | ¥255 (approx. USD 1.70) | ¥190-325 (approx. USD 1.27-2.17) |
| 20 stories or more | ¥338 (approx. USD 2.25) | ¥240-410 (approx. USD 1.60-2.73) |
Applying this benchmark to a whole rental building produces the following required amounts.
- 400 sqm (the model property): 400 sqm × ¥335 × 12 months = ¥1.608 million (approx. USD 10,720) per year
- 4,000 sqm: 4,000 sqm × ¥335 × 12 months = ¥16.08 million (approx. USD 107,200) per year
Against the model property's NOI of ¥4.987 million, ¥1.61 million represents 32%. Spend that money as if it were profit, and there will be nothing left for the exterior-wall and waterproofing work due in 12-15 years. Conversely, a deal that can comfortably set aside ¥1.61 million every year is structurally positioned to withstand a one-point interest-rate increase. The repair reserve is not an expense — it is the investment that keeps the building itself as an asset.
How to Start Whole-Building Apartment Investing: The Purchase Process and What Money Moves at Each Stage
Now let's translate the numbers above into an actual purchase process. Tracking "what you decide" alongside "how much money moves" at each step will make your due diligence faster.
Steps 1-3: From Setting Your Strategy to Verifying the Property
- Decide your investment strategy (cash outlay: ¥0). Individual or corporate ownership? Is the objective cash flow, or compressing your inheritance-tax valuation? Start viewing properties while this is still vague, and you won't be able to judge whether any given deal's terms are actually good. If you're buying through a company, start by reviewing your financial statements and remaining borrowing capacity.
- Quantify your selection criteria (cash outlay: ¥0). Set numeric cutoffs — "NOI yield of 4.5% or higher," "DSCR of 1.3 or higher," "built within the last 25 years," "within a 10-minute walk of the station." Without hard criteria, a salesperson's pitch will sway your judgment deal by deal.
- Verify the rent roll and surrounding market rents (cash outlay: actual inspection costs). Obtain a unit-by-unit list of contracted rent, lease start date, security deposit, and renewal date, and cross-check it against advertised rents for comparable nearby units. A building where many units are renting above the current market rate will lose income every time a tenant moves out. Re-run the NOI table shown earlier with the actual rent-roll numbers for the property you're considering.
Steps 4-6: From the Financing Inquiry to Handover
- Approach lenders for a financing pre-screen (cash outlay: ¥0; typical timeline: 2-6 weeks). Prepare three years of financial statements, tax returns, a statement of assets and liabilities, a property summary, the rent roll, and a projected income statement. Interest rate isn't the only thing to confirm here — as the earlier table showed, the loan term a bank offers can shift your required down payment by ¥23.63 million (approx. USD 157,500).
- Sign the sale and purchase agreement (cash outlay: earnest money + ¥30,000 stamp duty). Earnest money is typically set at around 5-10% of the purchase price — for the model property, that's a range of ¥5 million to ¥10 million (approx. USD 33,300-66,700). Before signing, confirm exactly where in the contract the financing contingency (融資特約) is written, and what its deadline is.
- Closing, registration, and handover (cash outlay: remaining balance + ¥6.49 million upfront costs + ¥4 million building consumption tax). Registration and license tax and the judicial scrivener's fee are settled on closing day. The real estate acquisition tax arrives separately, later, as a bill from the prefectural government, and must be self-reported within 30 days of the acquisition date. Build a line into your cash-flow plan for an approximately ¥1.23 million (approx. USD 8,200) bill arriving several months after closing.
After handover, your relationship with a property management company begins. Choosing on fee rate alone tends to cost you more in the end, through weaker leasing performance and less proactive repair recommendations. We've laid out the selection criteria in detail in How to Choose a Rental Property Management Company: 7 Points Owners Should Prioritize.
Where Beginners Go Wrong, and the Legal Safeguards That Protect You
Failures in whole-building investing tend to come less from poor judgment than from things that a simple check would have caught. Here are three safeguards grounded in law and government statistics.
Sublease and Rent Guarantees: The Rental Housing Management Business Act as a Yardstick
When a salesperson tells you "there's a rent guarantee, so vacancy isn't a risk," the yardstick to measure that claim against is the Rental Housing Management Business Act (賃貸住宅管理業法, Chintai Jūtaku Kanri Gyō-hō). This is a distinctly Japanese regulatory framework: it governs "sublease" (サブリース) master-lease arrangements, in which an operator guarantees an owner a fixed rent and absorbs the vacancy risk itself — a structure with no exact equivalent in the US, where "guaranteed rent" is not a regulated product category. It is closer in spirit to a UK rent-to-rent or guaranteed-rent scheme, but unlike that UK equivalent, it carries specific statutory disclosure obligations enforced by law. The Act regulates not only the sublease operator itself, but also anyone who solicits the owner into the arrangement, such as a related construction company or affiliated sales company.
- Prohibition on exaggerated advertising (Article 28; applies to sublease operators and solicitors): If an ad displays "rent guarantee" or "vacancy guarantee," it must also disclose, immediately adjacent to that claim, that the rent is subject to periodic review and can be reduced under Article 32 of the Act on Land and Building Leases (借地借家法). The disclosure must be presented so a reader would naturally perceive it as part of the same claim — font size, color, and background cannot be used to bury it.
- Prohibition on improper solicitation (Article 29; applies to sublease operators and solicitors): Deliberately withholding a fact that would affect the owner's decision — such as the future risk of a rent reduction — is prohibited. Cited examples of improper solicitation include describing only the benefits of the arrangement while failing to disclose that the operator can terminate the contract during its term, or that the owner needs "justifiable grounds" (正当事由) under Article 28 of the Act on Land and Building Leases to terminate from their own side.
- Pre-contract important-matters explanation and document delivery (Article 30; applies to sublease operators): Before signing, the operator must explain the possibility of a rent reduction and any conditions that could change during the contract term. If the operator later intends to exercise its right to demand a rent reduction under Article 32, Paragraph 1 of the Act on Land and Building Leases, it must first deliver a written document explaining the proposed reduced rent amount and the basis for it.
Solicitors — parent companies, construction companies, affiliated sales companies — are also subject to these regulations and their penalties. If an advertisement doesn't disclose the possibility of a rent reduction, or if the pre-contract explanation never mentions it, that alone is sufficient reason to walk away from that counterparty. We explain the sublease contract structure itself in more detail in The Contract Structure and Risks of Sublease (Guaranteed Master-Lease) Arrangements.
Real-World Vacancy: Building an Assumed Vacancy Rate Into Your Numbers
The claim "whole buildings carry lower vacancy risk" refers only to the diversification effect of having multiple units — it does not mean vacancy doesn't happen. The real-world rate can be checked against government statistics.
- In 2023, Japan had a total of 65,047 thousand housing units, of which 9,002 thousand were vacant — a vacancy rate of 13.8%.
- Of that total, 4,436 thousand units were vacant rental housing, accounting for 6.8% of all housing units and 49.3% of all vacant housing.
- In 2018, vacant rental housing stood at 4,327 thousand units, or 6.9% of total housing. Over five years, the count rose by roughly 110,000 units.
This 6.8% figure is a national average, and it swings widely by area, building age, and floor plan. The model property assumes a 5% vacancy-and-delinquency loss, but for regional properties or older buildings, budgeting for 10% or higher can be the more realistic assumption. We recommend calculating, before you buy, exactly how much a 1-point change in vacancy rate moves your annual numbers — for the model property, 1% equals ¥70,000 (approx. USD 467) a year. For designing leasing terms, our article Setting Rent by Working Backward From Your Target Yield, and Vacancy Countermeasures is also a useful reference.
What Happens When Tax Savings Becomes the Primary Goal
Every time depreciation compresses your taxable income, the building's book value falls by the same amount. Capital gains on sale in Japan are calculated as "sale price − (acquisition cost − accumulated depreciation) − transfer costs," so the more depreciation you've claimed, the larger your taxable gain at sale. The accurate way to think about this: some portion of the tax you saved during the holding period comes back due at sale. Depreciation is a deferral, not a permanent saving — a dynamic that will feel familiar to US investors who understand depreciation recapture under IRC Section 1250, even though the specific Japanese mechanics differ.
When tax savings becomes the primary objective, the tendency is to select a property for its depreciation potential even at a lower yield. But loan payments and repairs come due every single year regardless. Choose the property for its investment economics, and treat the tax effect as a byproduct, not the goal. Keeping that order intact is, in my view, the condition for making this kind of investment last. We cover the related mechanics in Tax-Saving Strategy in Condominium Investment: Depreciation and Loss Offsetting.
Frequently Asked Questions
Q1. How much down payment do I need for a whole-building apartment?
Work it backward from DSCR rather than a fixed percentage. On the model property (¥104 million acquisition price, NOI ¥4.987 million), securing a DSCR of 1.3 at a 1.944% interest rate on a 20-year loan requires about ¥40.48 million (39%) (approx. USD 269,900); stretch the loan to 30 years and about ¥16.85 million (16%) (approx. USD 112,300) is enough.
Q2. What percentage of the purchase price are upfront costs on a whole-building apartment?
On the model property, registration and license tax, real estate acquisition tax, stamp duty, and brokerage commission together total about ¥6.49 million (approx. USD 43,300), or 6.5% of the ¥100 million purchase price. Add the ¥4 million (approx. USD 26,700) consumption tax on the building portion, and the total rises to about ¥10.49 million (approx. USD 69,900), or 10.5%.
Q3. What's a typical yield for a whole-building apartment in Japan?
As of April 2026, expected (NOI-based) yields for studio-type whole-building rental housing are 3.6% in Tokyo's Jōnan area, 4.2% in Osaka, 4.5% in Nagoya and Fukuoka, and 5.0% in Sendai and Hiroshima. These use a different definition than the gross yield quoted in most sales materials.
Q4. Is new construction or a used building the better choice?
At the same budget, they aren't really comparable options. The 2023 RC construction cost is ¥314,300/sqm, so a new 400 sqm building costs about ¥125.72 million (approx. USD 838,100) for the building alone. New construction depreciates over 47 years, giving a thinner tax effect, but its advantage is a minimal near-term repair burden and an easier case for a longer loan term.
Q5. What's a typical property management fee?
Judge it by scope of service and leasing performance, not the fee rate alone. The model property assumes 5% of effective gross income (¥333,000/year, approx. USD 2,220), but the real cost depends heavily on how much is actually included — turnover restoration coordination, statutory inspections, delinquency follow-up. Confirming the scope of service in writing before signing is the reliable way to know what you're actually paying for.
Conclusion: In 2026, Judge Whole-Building Investing by "Rate Spread and Repair Funding," Not "Yield"
Let's put the numbers from this article back in decision order. First, gross yield is only useful as a screening cutoff — before you buy, calculate for yourself exactly how a 7.0% gross-yield property gets whittled down to 4.8% at the NOI level and 3.2% after the repair reserve. Second, don't set your down payment as a fixed ratio; work it backward from DSCR, and remember that loan term moves the number more than the down-payment ratio does. Third, build the "+1.0% interest rate" table before you commit, and choose a financing structure that survives it.
2026 is a year with a thin spread — expected yields of 3.6-5.0% against borrowing rates in the high-1% range. Precisely because the spread is thin, the quality of your operations shows up directly in your returns. Filling a vacancy one month sooner, executing repairs on schedule, and talking to your management company in numbers rather than generalities — these unglamorous habits are what show up in your asset's value ten years from now.
At INA&Associates, we see real estate not as a business that ends at the sale, but as one where we are entrusted with an asset and grow it over time. At the center of that work are our people (人財, jinzai — literally "human talent," the term we deliberately use in place of the more transactional 人材) who can both read the numbers and operate on the ground. If you are a business owner considering acquiring and operating a whole-building apartment, try plugging your own property's numbers into the tables in this article. Whichever line makes you pause is exactly the point worth discussing with us.
