When people in Japan start looking to buy an apartment, most stop at the same first fork: new construction, or a chūko manshon (中古マンション), a used resale condominium unit. Unlike many English-speaking markets, where new-build and resale sit on one continuous price curve, Japan's market treats the two as fairly distinct categories. A used unit has real advantages new construction cannot match, and it widens your choice of budget and location — in exchange for the buyer having to judge the building's condition and management quality directly, rather than relying on a developer's warranty. This article sets out the benefits of buying a used condominium in Japan and the points you must check before you commit.
Why Used Condominiums Have Become the Popular Choice
Japan's housing market used to run on a build-new, move-on cycle. In recent years, rising construction and labor costs have kept new-condo prices persistently high, making it genuinely hard to find a new unit in a preferred area. In central Tokyo this has reversed the calculus: at the same budget, locations out of reach for a new-build purchase become realistic once you consider resale.
Policy has moved the same direction, toward keeping the existing housing stock in use longer. Brokers must now explain the availability of a kenchikubutsu jōkyō chōsa (建物状況調査, a professional pre-purchase building inspection) when a brokerage agreement is signed, and insurance covering defects in existing homes is now available. The fact that a third party can verify a used home's condition is a major reason resale has become an easier, lower-risk choice.
For this reason, a used condominium should not be seen as a fallback for buyers who cannot afford new construction. I see it as a rational choice: inspect the actual unit and building, then secure a price and location you are genuinely satisfied with.
Five Reasons to Choose a Used Condominium
There are five main reasons buyers deliberately choose a used condominium over a new one.
Lower Purchase Price Than New Construction
A new condominium's price bakes in selling costs such as running a model room and advertising. This markup, the shinchiku premium (新築プレミアム), tends to get corrected once the unit re-enters the resale market. The same building commonly trades at a different price level once it becomes a resale property than it did as new.
How large that gap is depends heavily on location and age. A station-front unit in central Tokyo may barely fall in price, or even exceed its original cost. A blanket claim that resale is always a fixed percentage cheaper oversimplifies things; check actual closed transactions for the specific area.
A Larger Pool of Listings Makes It Easier to Target Your Preferred Area
New condominiums are supplied only at specific times and places, while a steady volume of resale units is always on the market. The pool of units available in a given school district or commute radius is far larger for resale than for new construction, so you can search without compromising your priorities. The less flexible you can be on location, the greater this advantage becomes.
You Can Inspect the Actual Unit and Living Environment Before You Buy
Most new condominiums are sold off-plan or mid-construction, so buyers cannot experience the real sunlight, view, or noise before signing. With a resale unit you can check all of this directly. Beyond the unit itself, you can see how clean the common areas are, how the garbage area is kept, and how the bicycle parking is used — a proxy for whether the building's kanri kumiai (管理組合, the mandatory owners' association) is functioning well.
View the property more than once, on a weekday and a weekend and at different times, since traffic noise and light both change with the hour.
Renovate and Remodel to Your Own Taste
Because the purchase price is lower, the savings can fund an interior upgrade. Buyers who replace plumbing, kitchen or bath fixtures, or reconfigure the floor plan can reach near-new-build comfort on their own terms. One caveat: even work inside your own exclusively-owned unit can be restricted by the kanri kiyaku (管理規約, management bylaws). Flooring often must meet a minimum sound-insulation rating, and window sashes or the entrance door are frequently classed as common-area property owners may not replace.
Tax Incentives Are Also Available
A used home can still qualify for the jūtaku rōn kōjo (住宅ローン控除, mortgage tax credit), a reduced real estate acquisition tax, and a reduced registration tax, if requirements are met. The mortgage credit generally requires floor-area and income conditions, and for an existing home, compliance with the shin-taishin kijun (新耐震基準, post-1981 seismic standard; see below). If both spouses take out separate mortgages, both may claim the credit.
Tax rules here change often. The rate, cap, and deadline are revised year to year, so verify current rules with the National Tax Agency (国税庁) or a tax accountant before signing.
Comparing New Construction and Resale Side by Side
Neither option is objectively better — they have different characters. Breaking it down by criterion clarifies which should matter more to you.
| Comparison point | New condominium | Used condominium |
|---|---|---|
| Price level | Tends to be higher, including selling costs | Adjusted to market price, tends to be more affordable |
| Location options | Constrained by where and when units are supplied | Higher inventory makes selection easier |
| Inspecting the unit | Mainly floor plans and a model room at contract time | You can check the actual unit and common areas |
| Newness of fixtures | Latest specs; no near-term replacement needed | Replacement costs should be expected as the building ages |
| Seller's liability | Developer bears liability for a relatively long period | An individual seller's liability period tends to be shorter |
| Judging management | No track record yet; you are forecasting the future | Judgeable from past repair history and reserve fund balance |
| Time to move in | Waiting for construction completion can be a factor | Moving in within a short period is generally easier |
The biggest advantage of buying used sits in the second row from the bottom. Forecasting the future from an actual track record of management and repairs is reassurance no new-build purchase can offer.
What to Check Before Buying a Used Condominium
Every advantage above has a corresponding item you need to verify. Skip these checks, and unexpected costs follow after you have already bought.
Building Age and Seismic Standards
The key dividing line for a condominium's earthquake resistance is whether the building permit (kenchiku kakunin, 建築確認) was issued before or after June 1, 1981. Buildings permitted earlier were designed to the kyū-taishin kijun (旧耐震基準, old seismic standard), so check for a seismic diagnosis and any reinforcement work. A pre-1981 building can also work against you for the mortgage tax credit or a lender's loan decision.
That said, an old-standard building should not be ruled out automatically. A unit that has completed reinforcement work, or that can obtain a taishin kijun tekigō shōmeisho (耐震基準適合証明書, a certificate of seismic compliance), can reasonably stay on your shortlist. Gather the evidence before deciding, rather than rejecting on the label alone.
Management Quality and the Repair Reserve Fund
There is a well-known saying in Japan's condominium market: buy the management, not just the unit. The building's lifespan and asset value depend on how well its kanri kumiai is run. Before buying, review the jūyō jikō chōsa hōkokusho (重要事項調査報告書, a due-diligence report from the management company), the bylaws, the latest general meeting minutes, and the long-term repair plan.
One point buyers often miss: if the previous owner was behind on management fees or reserve fund contributions, the buyer can inherit that unpaid debt. Under the Kubun Shoyū Hō (区分所有法, Act on Building Unit Ownership), arrears can be claimed against the next owner — a liability that would not typically transfer this way in a US or UK residential purchase. Always confirm whether arrears exist before final settlement.
| Document to check | What to look for |
|---|---|
| Jūyō jikō chōsa hōkokusho (due-diligence report) | Total reserve fund balance, any arrears, planned repairs |
| Long-term repair plan | Plan period, timing and funding of the next major repair |
| General meeting minutes | Ongoing concerns among residents, fee increases or special levies |
| Management bylaws | Renovation restrictions, rules on pets, instruments, short-term rentals |
| Repair history | Record of exterior wall, waterproofing, and plumbing renewal work |
Major renovation work typically runs on a 12-to-15-year cycle. If the reserve balance falls short of the plan, a future fee increase or special levy becomes a real possibility. A building with an unusually low reserve contribution is not a bargain — it is a cost that has been deferred, and it will eventually land on someone's bill.
Mortgages and Collateral Valuation
If a lender's collateral valuation comes in below the purchase price, it may decline to finance the full amount. Older buildings can also see a shorter maximum loan term; the statutory useful life of a reinforced-concrete building in Japan is 47 years, and some lenders use that as a benchmark.
The countermeasure is simple: apply for pre-approval with several lenders and compare terms. Even for the same property, valuation, rate, and term can differ by lender. Work out early how much cash you can bring yourself.
Aging Fixtures and Non-Conformity Liability
Equipment such as the water heater, air conditioning, and intercom will need replacing soon after move-in if it has exceeded its useful life. Ask the seller to replace such items before handover, or build the cost into your budget.
When the seller is a private individual, the keiyaku futekigō sekinin (契約不適合責任, liability for non-conformity with the contract) is usually limited to a few months after handover, and some contracts waive it entirely. If concerned, commission a building inspection and consider kizon jūtaku baibai kashi hoken (既存住宅売買瑕疵保険, defect insurance for existing home sales) where available.
Budgeting: Estimating the Total Costs
You cannot judge a purchase by the listed price alone. Closing costs, starting with the brokerage commission, are added on top, so it is safe to budget roughly 6% to 9% of the purchase price for these additional costs.
| Cost item | Details and estimate |
|---|---|
| Brokerage commission | Above JPY 4,000,000 (approx. $26,000 at 155 JPY/USD), the legal cap is generally price × 3% + JPY 60,000 (approx. $390) + consumption tax |
| Registration costs | Registration and license tax plus the judicial scrivener's fee; check whether a reduction applies |
| Loan-related costs | Administration fee, guarantee fee, stamp duty, fire insurance premium |
| Real estate acquisition tax | Levied after acquisition; a reduction is available if requirements are met |
| Proration of management fees, etc. | Settled on a per-diem basis as of the handover date |
| Renovation costs | Varies widely with scope of work; confirm with an individual quote |
After purchase, running costs continue: management fees and reserve contributions monthly, fixed asset tax and city planning tax annually. Budgeting around the mortgage payment alone will squeeze the household later. We recommend the reverse order: decide the total monthly outflow you can sustain first, then work backward to your maximum purchase price.
The Purchase Process, Step by Step
For first-time buyers, here is the standard sequence.
- Build a budget and obtain mortgage pre-approval
- Decide your priority area and conditions, then gather listings
- View the property, checking common areas and the neighborhood as well as the unit
- Request the management documents and check the repair plan and reserve status
- Commission a building inspection (kenchikubutsu jōkyō chōsa) if needed
- Submit a purchase offer and negotiate price and handover terms
- Receive the jūyō jikō setsumei (重要事項説明, statutory pre-contract disclosure), sign the sale and purchase agreement, and pay the deposit
- Proceed with the mortgage's final approval and sign the loan agreement
- Do a final walk-through of the unit and fixtures before handover
- Settle the remaining balance, register the transfer of ownership, and receive the keys
Steps 4 and 5 matter most. The contract proceeds even if you skip them, but whatever risk you skip past comes back to you after you have already bought.
How to Spot a Condominium That Will Hold Its Value
A condominium is a home, but also an asset you may eventually sell or rent out. Units that hold value tend to share common traits.
- Within about a 10-minute walk of the nearest station, or otherwise highly convenient for transit
- Served by multiple train lines, or positioned to benefit from redevelopment or improving infrastructure
- A large enough total unit count to give the owners' association a stable financial base
- A clear repair history, with the long-term repair plan kept properly up to date
- Attributes hard to replicate elsewhere, such as sunlight, views, or floor level
- Priced in line with recent comparable sales nearby, not sharply above them
Conversely, a unit that stands out purely for being cheap almost always has a reason. An old-standard building with no reinforcement planned, a depleted reserve fund, or unfavorable zoning will all become reasons to discount the price again at resale. Whatever makes a unit cheap when you buy it will make it cheap when you sell it too.
INA&Associates' Perspective, and a Summary
At INA&Associates, we treat every real estate transaction not as a one-off sale, but as a decision on the timeline of a client's life. Pushing a client toward a quick decision on price alone ultimately works against their long-term interests, so we explain drawbacks with the same energy as benefits.
For used condominiums, the three advantages of price, location, and inspecting the actual property are genuinely significant. But that advantage only holds if you accept the work of verifying management quality and the repair plan yourself. For a buyer willing to put in that effort, a used condominium can be more rational than new construction.
And that judgment is only as good as the people supporting it. We believe our jinzai (人財, our term for staff, written with the character for “treasure”) are our greatest asset, and we invest in a team that can read the documents and explain future risks honestly. When unsure how to choose a property, pick an advisor who discloses information honestly as your partner. Related articles are collected in our column archive, which we invite you to browse as well.
Frequently Asked Questions
In the end, which is the better value: a used condominium or a new one?
A used unit tends to be cheaper and may reach a better location on the same budget. In exchange you take on aged-equipment replacement costs and the work of verifying management quality. Compare total cost — price plus expected future repairs — and decide on whichever conditions matter most.
Can I still use the mortgage tax credit on a used condominium?
Yes, if conditions are met. Beyond floor-area and income requirements, an existing home is generally also required to comply with the new seismic standard (shin-taishin kijun). The credit rate and borrowing cap are subject to revision, so check the National Tax Agency's current guidance before signing, and consult a tax accountant if needed.
What building age should I be targeting for a used condominium?
There is no single correct answer, but buildings that meet the new seismic standard and have already gone through the initial price correction after new-build tend to be easiest to evaluate. What matters more than the age figure is the substance behind it: has major renovation been carried out on schedule, and does the reserve fund match the plan? Two buildings of the same age can differ enormously.
What should I do if I cannot secure the mortgage amount I wanted?
Three main options: increase the cash you put in yourself, widen your search to properties whose collateral valuation matches what you can borrow, or reconsider the loan term or lender. Start by getting pre-approval from several lenders and comparing valuations and terms. In the long run, it is healthier to choose a different property that fits your financing than to stretch your household budget with an unaffordable loan.
