Ask five people whether you should rent or buy in Japan and you'll get five confident, contradictory answers. The honest truth is that there isn't a universal answer — there's a framework, and the right output depends on inputs that are personal to you: how long you're staying, how stable your visa is, and how you feel about being tied down. This page won't tell you to buy, and it won't tell you to rent. It will walk through how to think about the decision so you can run your own numbers with your own assumptions.
The case for renting
Renting wins on flexibility. If your job could move you, your visa status isn't fully settled, or you simply don't know if you'll be in Japan in five years, renting keeps your options open. There are no transaction costs to recover, no building to sell in a falling market, and no exposure to the depreciation dynamics described below. Someone else — the landlord — is on the hook for major repairs, roof leaks, and structural issues. Japanese rents are also relatively stable over time and, in many areas outside central Tokyo, low relative to income, which softens the usual "rent is dead money" argument.
Renting also completely sidesteps the foreigner mortgage hurdle — the fact that many lenders want permanent residency, long tenure at a Japanese employer, or a Japanese guarantor before they'll extend a home loan. If you can't easily get financing, the rent-vs-buy debate is somewhat academic anyway.
That said, renting in Japan isn't free of up-front pain. Deposits, key money, agent fees, and guarantor company charges can add up to a startling multiple of your monthly rent before you even get the keys. If you're weighing renting seriously, it's worth costing that side of the ledger properly rather than assuming it's the "cheap" option by default — a Japan move-in cost calculator is a useful tool for that, and why renting's up-front move-in costs run so high explains where that money actually goes.
The case for buying
The pro-buying argument is intuitive: rent paid is gone forever, while a mortgage payment builds equity — at minimum, equity in the land underneath your home. Owner-occupier mortgage rates in Japan have been very low for a long time, which means a monthly loan payment can end up comparable to, or even lower than, rent on an equivalent property. Buying also offers stability and the freedom to renovate, hang shelves, keep pets without asking permission, and stop worrying about lease renewals. For long-term residents or permanent residency holders who are confident they're staying put, the maths can genuinely work out in favour of owning.
But the case for buying in Japan comes with an asterisk that doesn't exist in many other housing markets, and it's important enough to get its own section.
The depreciation factor
In many countries, "buying a house" is implicitly "buying an appreciating asset." In Japan, that assumption often doesn't hold. Japanese buildings — especially wooden houses — tend to lose accounting and market value over time in a fairly predictable way, often being valued near zero after roughly 20 to 25 years, regardless of how well-maintained they are. Land is different: it holds value or moves with its own local market, largely independent of what's built on it. This is the depreciation culture explained in more detail, but the short version is that new-build culture and short building lifespans are baked into how the market prices homes.
Reframe the purchase: buying property in Japan is usually better understood as buying land plus a depreciating structure, not buying one appreciating asset. That doesn't make it a bad decision — but it changes what "building equity" actually means, and it means you're less likely to profit from the building itself than you might expect coming from a market where houses typically appreciate.
The inputs to weigh honestly
Instead of asking "should I buy," it helps to answer a shorter list of honest questions first:
- Time horizon. Transaction costs on a purchase only amortise if you stay long enough to spread them out — see the transaction costs of buying, which typically run around 6–10% of the purchase price (諸費用, shohiyō) and are essentially unrecoverable if you sell soon after.
- Visa and PR stability. The more settled your status, the less risk there is in committing to one location for a decade or more.
- Loan access. Can you actually get a mortgage on reasonable terms as a foreign resident, and does that change the comparison?
- Land vs. building split. How much of the purchase price is land (which tends to hold value) versus structure (which tends to depreciate)? This ratio matters more in Japan than in most housing markets.
- Ongoing costs. Property tax (固定資産税), and for a mansion, monthly management and repair reserve fees (修繕積立金), or general maintenance for a house — the ongoing ownership costs don't stop once the loan is paid off.
- The intangibles. Stability, a sense of belonging, and the freedom to make a place your own, weighed against the flexibility to leave without friction.
A thinking-tool rule of thumb
This is offered as a way to organise your thinking, not as a verdict: the shorter and less certain your time horizon, the more renting tends to win on pure economics, because you won't be around long enough to absorb the transaction costs or ride out the building's depreciation curve. The longer and more settled your situation — strong PR status, a long-term job, a location you're confident about — the more buying can make sense. But because of the depreciation factor and the transaction costs discussed above, the real break-even point in Japan is often longer than newcomers expect, sometimes by several years compared to home-country intuition.
None of this replaces running your own numbers. Try the cost calculator to model both sides with your actual rent, purchase price, and assumptions, and check the FAQ if you have specific questions about how the inputs work.
