When I first looked at Japanese real estate, the idea that a wooden house could be worth nearly zero on paper after 22 years seemed absurd. A ¥20 million building, valued at zero? It took me a while to separate the accounting reality from the physical one. Japan property depreciation works differently from what most foreign investors expect—and once you understand it, you can use it rather than fear it.
Buildings depreciate for tax and accounting purposes; land does not. In 2025, Japan’s national land prices rose 2.7%, the strongest pace in 34 years according to the Ministry of Land, Infrastructure, Transport and Tourism. Physical structures can remain sound for 65–77 years when maintained, even though the tax code may treat them as fully depreciated. This guide explains how Japan property depreciation actually works, why the split between land and building matters, and how informed investors turn depreciation into a tax advantage.
The Truth About Japan Property Depreciation
The rule is simple: buildings depreciate, land does not. The Japanese tax code assigns each building type a “statutory useful life” that sets the depreciation period. Wooden houses depreciate over 22 years; reinforced concrete (RC) condominiums over 47 years. These timelines are accounting conventions, not predictions of when the building falls apart.
Research from ScienceDirect indicates that Japanese residential structures lose roughly 50% of building value within the first 10 years, with depreciation slowing after that. The building doesn’t collapse at year 22—the tax code simply allows full depreciation by then. In my experience, the biggest mistake is assuming “depreciated” means “worthless.” It doesn’t.
What actually matters for value:
- Total property value = Building value + Land value
- Building value decreases over the statutory useful life
- Land value moves with location and demand
- Overall value can rise, fall, or stay flat depending on the balance

Land vs Building: Why This Split Matters
Every Japanese property purchase is really two assets: land and building. They follow completely different trajectories. Land cannot be depreciated for tax purposes and has no expiration—you own it in perpetuity. Buildings start depreciating from day one on a fixed schedule, regardless of condition.
Tokyo’s 23 wards saw residential land prices rise 7.9% in 2024, with commercial land up 11.8%. A well-maintained building and a neglected one depreciate at the same rate under the tax code. That disconnect is where both risk and opportunity sit.
Here’s how the two components compare:
| Factor | Land | Building |
|---|---|---|
| Tax depreciation | None allowed | Required annually |
| Value over time | Market-dependent | Decreases to zero |
| Ownership duration | Perpetual | Subject to demolition |
| Investment focus | Location-driven | Condition-dependent |
| Tax benefit | Appreciation taxes | Depreciation deductions |
Smart investors pay attention to the land-to-building ratio. A property with 60% land value holds overall value better than one with 20% land and 80% building, all else equal.
Statutory Useful Life by Construction Type
Japan’s National Tax Agency sets statutory useful life by construction material. These periods drive annual depreciation rates for tax.
The table below is the reference you’ll use when estimating deductions. I’ve had to double-check construction type on the property registration more than once—getting it wrong changes your numbers significantly.
| Construction Type | Statutory Useful Life | Annual Depreciation Rate |
|---|---|---|
| Wooden residential | 22 years | 4.545% |
| Light steel frame | 19 years | 5.263% |
| Heavy steel frame | 34 years | 2.941% |
| Reinforced concrete (RC) | 47 years | 2.128% |
| Steel reinforced concrete (SRC) | 47 years | 2.128% |
Rates assume straight-line depreciation for buildings acquired after April 1, 1998. Wooden houses depreciate fastest: a ¥10 million building loses about ¥454,500 per year and reaches zero for tax purposes after 22 years. RC condominiums depreciate at roughly ¥212,800 per year for the same building value—slower depreciation plus stronger locations help explain why Tokyo condos have appreciated overall despite building depreciation.
Why Japanese Buildings Depreciate So Fast
Foreign buyers often ask why Japanese buildings depreciate more aggressively than in the West. Several factors stack up. Much of Japan’s postwar housing was built quickly with cheaper methods; modern standards have improved, but the perception of older stock persists. Japanese buyers traditionally prefer new construction—The Economist notes only about 15% of homes sold in Japan are secondhand, versus much higher shares in Western markets.
Building codes also update frequently, especially after major earthquakes. The 1981 revision created a sharp divide between “old” and “new” earthquake-resistant buildings; pre-1981 properties face more skepticism from buyers and lenders. Japan’s “scrap and build” culture treats houses as structures to be demolished and rebuilt rather than renovated. The average demolition age is around 30 years, compared to 55 in the United States and 77 in the United Kingdom—so the 30-year figure reflects when people choose to demolish, not when buildings fail. The tax code reinforces this: with wooden houses fully depreciated in 22 years, there’s little tax reason to keep them on the books.
The 30-Year Myth: What Research Actually Shows
“The average Japanese house is worthless after 30 years” is a line you’ll see repeated. It’s misleading. The 30-year figure is average demolition age—driven by redevelopment, preference for new builds, and tax incentives—not structural failure.
Alternative methodologies suggest actual lifespans of 65–77 years with proper maintenance. Many traditional wooden structures have survived much longer. The disconnect between market value and physical condition is where opportunities appear: akiya (vacant houses) often sell at steep discounts despite being structurally sound. Our akiya investment guide goes deeper. Older RC condominiums in good locations may show zero building value on paper but still function well as rentals.
ScienceDirect research notes that structure value loses about 50% in the first 10 years, with depreciation continuing more gradually to around 30 years, and that the “taste for newness” effect has been weakening in urban areas. The myth oversimplifies: properties don’t become worthless; building value depreciates while land value and rental potential can stay strong.
Japan Property Depreciation as a Tax Benefit for Investors
For rental investors, depreciation becomes a real tax advantage. Annual depreciation expense offsets rental income and reduces taxable income—a non-cash expense that doesn’t require extra spending.
When you buy rental property in Japan, you don’t deduct the full building cost in year one. You spread it over the building’s statutory useful life. Example: building acquisition cost ¥20,000,000, RC construction (47 years, 2.128% rate). Annual depreciation deduction = ¥20,000,000 × 0.02128 = ¥425,600. If gross rental income is ¥1,200,000 and you have ¥425,600 in depreciation plus other expenses, taxable rental income drops substantially.
The first time I ran the numbers on an older wooden building, I was surprised how much faster depreciation accelerated under the “remaining useful life” formula—larger annual deductions, but also more recapture risk when selling. Worth modelling both sides.
Important limitations: when you sell, previously claimed depreciation reduces your cost basis and can increase capital gains tax. As of January 1, 2021, losses from depreciation on second-hand overseas rental properties can no longer offset other Japanese income. You can only deduct depreciation against rental income (with limited exceptions), and you need solid records of building cost and depreciation claimed. For more on rental taxation, see our Japan rental income tax guide and complete guide to buying property in Japan.
How to Calculate Building Depreciation
Calculation follows National Tax Agency rules. You need the building-versus-land split (from the purchase contract, fixed asset tax assessment, or an appraiser), the construction type from the property registration (木造 = wooden, 鉄骨造 = steel frame, 鉄筋コンクリート造 = RC), and the correct depreciation rate.
For new buildings, straight-line rate = 1 ÷ statutory useful life. Wooden: 0.04545; light steel: 0.05263; heavy steel: 0.02941; RC/SRC: 0.02128. Annual depreciation = building acquisition cost × rate. If you acquire mid-year, prorate by months owned (e.g. purchase April 1: 9/12 of the annual amount in year one).
For used properties, remaining useful life matters. Within statutory life: Remaining life = (Original life − Elapsed years) + (Elapsed years × 0.2). Example: 15-year-old wooden house → (22 − 15) + (15 × 0.2) = 10 years remaining, rate 10%. When the building has exceeded its useful life (e.g. 25-year-old wooden): modified useful life = original useful life × 0.2 (e.g. 22 × 0.2 = 4.4 years), giving a much higher annual rate and larger deductions over a short period.
Condos vs Houses: Different Depreciation Rates
Condominiums usually use RC (47-year life, ~2.1% per year); detached houses are often wooden (22 years, ~4.5% per year). That difference affects both tax deductions and value retention.
Condos tend to sit in stronger land markets where appreciation can outweigh building depreciation. Detached houses offer faster depreciation and larger annual deductions, full land ownership, and more renovation freedom, but value retention depends heavily on location. For compact urban returns, see our Tokyo 1K apartment investment yield guide. There’s no single right answer—it depends whether you’re optimising for cash flow and deductions or for long-term value and liquidity.
Land Value Trends: The Other Half of the Equation
While buildings depreciate on a schedule, land values move with the market. In 2025, national land prices rose 2.7% (MLIT); Tokyo’s 23 wards saw residential land up 7.9% and commercial 11.8%. Location dominates: central Tokyo and Osaka cores, regional city centres, and areas with new transit or tourism can appreciate strongly; rural and declining areas often don’t. A central Tokyo property can see land appreciation of 7–10% per year while the building depreciates 2–4%—net appreciation. The same building in a stagnant area may show net depreciation. Our complete guide stresses location research for this reason.
Depreciation Strategies for Foreign Investors
Strategies split roughly into tax-focused versus value-preservation. Tax-focused: older buildings (accelerated remaining-life depreciation), higher building ratio, wooden construction, reinvesting tax savings—but only if the investment fundamentals work first. Value-focused: RC condos, high land ratio, prime locations, newer buildings. Most investors I’ve seen do best with a middle path: urban markets with land appreciation potential, moderate depreciation deductions, positive rental cash flow, and a 10–15 year horizon. Don’t let tax benefits drive a bad purchase.
FAQ: Japan Property Depreciation
Why do Japanese houses depreciate so fast? Do Japanese houses really depreciate?
Japanese buildings depreciate quickly because of tax rules, culture, and history. In practice, the building value depreciates on paper while land value and physical condition can hold up—so the answer is nuanced, not simply “yes, they’re worthless.” The tax system assigns short statutory lives (22 years for wooden), which influence valuations. Culturally, buyers prefer new construction—only about 15% of homes sold are secondhand. Postwar construction quality and frequent code updates after earthquakes also play a role. Physically, structures can last 65–77 years with maintenance; rapid depreciation reflects accounting and preference, not structural necessity.
Does land depreciate in Japan?
No. Land cannot be depreciated for tax purposes. Only the building qualifies for depreciation deductions. Land values rise, fall, or stay flat with the market. When evaluating any Japanese property, always separate land value (market-driven) from building value (depreciating).
How long does a house last in Japan?
The 30-year figure is average demolition age—when owners choose to rebuild or redevelop—not structural failure. Research suggests properly maintained buildings can remain sound for 65–77 years. Many traditional buildings have lasted far longer. So the common belief that “Japanese houses are worthless after 30 years” is wrong: they’re often demolished by choice, not because they’ve failed.
Can I claim depreciation on rental property in Japan?
Yes. You must claim depreciation on the building portion; it’s treated as a necessary expense that reduces taxable rental income. The amount depends on construction type and age. New RC condos run about 2.1% per year; wooden houses about 4.5%. Deductions can materially reduce tax while you own the property; recapture may apply on sale.
Do condos depreciate slower than houses in Japan?
Yes. Most condos are RC (47-year life, ~2.1% per year); typical wooden houses have 22 years (~4.5% per year). Condos also tend to be in stronger land markets. Tokyo condos have appreciated in recent years because land gains have outweighed building depreciation.
Japan property depreciation vs appreciation: what matters more?
For investment, both matter. Building value depreciates on a fixed schedule; land value moves with the market (appreciation in strong locations). Japan property depreciation vs appreciation often favours land: in prime Tokyo or Osaka, land gains can outweigh building depreciation so the overall property appreciates. In weak locations, net value can fall. Focus on the land-to-building ratio and location.

Japan property depreciation works differently from Western markets, but it’s manageable once you understand the land-versus-building split, statutory useful life, and tax implications. Focus on location, construction type, and rental fundamentals; treat depreciation as a factor you can use for tax efficiency rather than something to fear. My own view: the investors who struggle are the ones who ignore depreciation or assume the worst; the ones who do well run the numbers and plan around it.
