The numbers, from the official survey
The Statistics Bureau's Housing and Land Survey () counted empty homes out of total, a vacancy rate of , both record highs. That is the figure in every headline. But most of those homes are not the lonely cheap house people picture:

The category that matters for a bargain-hunter is the last one: 賃貸・売却用及び二次的住宅を除く空き家, the long-term idle homes that are not for rent, not listed for sale, and not holiday homes. There are of those ( of all homes). And of the genuinely idle homes, the detached houses, the ones you can imagine renovating, number about . Still a lot, but a fraction of the nine-million headline.
Why akiya are cheap, and why cheap is not the whole price
A house can be listed for a few million yen, sometimes near zero, for real reasons. In Japan a wooden house is often treated as a depreciating asset with little paper value after a few decades, so the price is mostly the land. When the land is in a depopulating (過疎) area, that land is cheap too. None of that is a trick. But the low price usually comes with costs that are easy to miss:
- Renovation. Many akiya have sat unused for years. Roof, plumbing, wiring, insulation, damp and pests can add up to more than the purchase price. Budget for a building inspection.
- Old earthquake standard. A house built before June 1981 (旧耐震) may need seismic retrofitting to be safe and to qualify for some loans and tax reductions.
- 再建築不可. Some plots cannot legally be rebuilt on, usually because they lack the required road frontage. You can repair the existing house but not replace it, which limits value and financing.
- Leftover belongings and demolition. Clearing a house full of the previous owner's things (残置物), or demolishing an unsalvageable building, is a real bill you may inherit.
- Location. The cheapest akiya are cheap because they are far from work, transport and shops. That is a lifestyle cost, not just a money one.
- The transaction costs still apply. Even on a cheap house you pay the registration and acquisition taxes, the scrivener and, through a brokerage, the agent fee. Run the number in the cost calculator so a "¥3 million house" does not surprise you at settlement.
Akiya banks (空き家バンク)
An akiya bank is a listing service, usually run by a municipality, that connects owners of empty homes with people who want them. The national government runs an aggregated version through MLIT (国土交通省), pulling many local banks into one search. They are a genuine and useful route, especially for rural homes that never reach the big commercial portals, but set expectations:
- Listings are thin and vary enormously by town; the best homes go quickly.
- Many towns attach conditions, such as moving in to live, or offer renovation or relocation subsidies you have to apply for.
- You still buy through the normal process, with a contract, 重要事項説明 and registration. An akiya bank is where you find the house, not a shortcut around the paperwork.
Buying one, in practice
The process is the same as any Japanese home purchase: search, view, offer, contract, settle, register. The difference with an akiya is the due diligence, which matters far more than usual: get the building checked, confirm the plot can be rebuilt on, ask what is included and what must be cleared, and price the renovation before you commit. Our step-by-step buying guide walks through the whole sequence, and the calculator gives you the transaction costs on top of the price.
