When a tenant moves out of a rental property in Japan, few line items trigger as many disputes as the cost of repairing scratches, dents, and stains on the flooring. What makes this a uniquely Japanese problem for international investors is the underlying rule: under the restoration guidelines issued by Japan’s Ministry of Land, Infrastructure, Transport and Tourism (MLIT, 国土交通省), flooring is treated so that natural aging is deliberately “not taken into account” for partial repairs — a framework both landlords and tenants must understand precisely, and one that has no direct equivalent in most Western rental markets.
Is flooring included among depreciable assets?
The basic principle for repair costs in a Japanese rental is that ordinary wear and gradual aging — keinen rekka (経年劣化, deterioration over time) and tsūjō sonmō (通常損耗, wear from normal use) — are borne by the landlord, while damage caused by a tenant’s negligence or intentional acts is borne by the tenant. Most fixtures and equipment are assigned a statutory useful life (耐用年数, taiyō nensū), and the tenant pays only the portion remaining after the aged-out value is subtracted. That subtraction is the logic of depreciation. For an overseas investor, this is worth pausing on: unlike the vague “normal wear and tear” standard familiar in US, UK, or Australian leases, Japan attaches a quantified, year-based depreciation curve to most interior elements — which is precisely why the treatment of flooring, an exception to that curve, becomes so consequential at move-out.
For partial flooring repair, elapsed years are not considered
Flooring itself is not assigned a statutory useful life, and under the MLIT genjō-kaifuku (原状回復, restoration-of-rental-property) guidelines, elapsed years of residence are not taken into account for “partial repair.” In practice this means that if a tenant scratches or gouges a section of the floor, the full repair cost falls to the tenant no matter how many years they have lived there. For investors used to markets where every fixture depreciates toward zero, this is the counterintuitive part: a floor damaged in year one and the same floor damaged in year ten carry the same tenant liability, because the guideline denies any aging discount on a partial fix.
Full replacement is the exception
There is, however, an important exception. When full replacement of the flooring is required, the building’s useful life is used as the yardstick (wooden construction: 22 years; steel-frame: 34 years; reinforced concrete: 47 years, and so on), elapsed years are factored in, and the tenant’s share of the cost is reduced. The distinction matters commercially: a scratch that can be spot-repaired leaves the tenant fully exposed, but damage severe enough to demand replacing the whole floor pushes the calculation onto the building’s long depreciation schedule — often shifting most of the cost back to the owner. Unlike Western markets where flooring is typically valued and depreciated as a standalone item, Japan folds full-floor replacement into the depreciation life of the building shell itself.
What else is excluded from depreciation besides flooring?
The following items are also treated without any consideration of elapsed years, so the same caution that applies to flooring applies to them:
- Tatami facing, fusuma (sliding-door) paper, shōji (paper screen) paper, and joinery components
- Pillars and structural posts
- Loss of keys
- Move-out room cleaning
When is the right time to replace flooring?
From an owner’s property-management standpoint, knowing when to replace flooring is essential — both to protect asset value and to avoid the move-out disputes above. For a foreign investor holding a Japanese rental, replacement timing is not merely maintenance; it is a positioning decision about how the unit will show to the next tenant in a market where interior condition weighs heavily on rent and vacancy.
Composite flooring: 10 to 15 years as a guide
Ordinary composite flooring (plywood plus a surface sheet) has a durable life of roughly 10 to 15 years. Solid-wood flooring (100% natural timber) lasts 30 years or more and holds up far longer. In contrast to many Western rental units where wall-to-wall carpet is periodically ripped out and replaced, Japanese owners are choosing between a shorter-lived composite surface and a premium solid-wood floor whose longevity can materially change the long-run capital-expenditure profile of the asset.
Act early when scratches, stains, or fading stand out
Large gouges become an injury risk. Leaving fading, lifting, or peeling unaddressed lets the condition worsen and drives repair costs higher, so early action is the economical choice. For an absentee overseas owner relying on a management company, this argues for scheduling inspections proactively rather than waiting for a tenant complaint.
Squeaks and creaking may signal a structural problem
When floor squeaking originates in the deterioration of structural members, it risks affecting the entire building. Commission a specialist inspection, identify the cause, and address it accordingly — a discipline that matters especially in Japan’s older wooden housing stock, where surface symptoms can mask deeper structural wear that a purely cosmetic fix would leave unresolved.

Frequently asked questions (FAQ)
Q. If I damage the flooring, do I have to pay the full amount?
For a partial repair, elapsed years are not considered, so in principle the entire repair cost falls to the tenant. If full replacement is required, the share of the cost is calculated based on the building’s useful life.
Q. What is the statutory useful life of flooring?
No statutory useful life is set for flooring on its own. When a full replacement is needed, the useful life for the building type applies (wooden construction 22 years, reinforced concrete 47 years, and so on).
Q. When should the landlord replace the flooring?
Roughly 10 to 15 years for composite flooring, and over 30 years for solid wood. If scratches, fading, or squeaking appear, checking the condition and acting early helps preserve the property’s value.
Q. Is the useful life of wallpaper (cloth) different from flooring?
Yes. Wallpaper is treated as having a useful life of 6 years, and elapsed years are taken into account. After ten or more years of residence, the tenant’s share of any replacement cost becomes very small.
