What Does Akiya Mean?
Japan's Vacant Houses Explained

Akiya (空き家) literally means "empty house" in Japanese. The word is made of two parts: 空き (aki, empty or vacant) and 家 (ya or ie, house). It refers to any residential property that is currently unoccupied — from a near-new suburban house whose owner moved away, to a century-old farmhouse slowly returning to nature.

Not all akiya are the same

The word akiya covers a huge range of properties. The internet tends to show the extremes — either a collapsing ruin listed for ¥0, or a beautifully renovated kominka turned into a guesthouse. The reality is more nuanced. Japan's 2023 Housing and Land Survey counted 9 million vacant dwellings, and they fall into several categories.

Some are held for future sale or rental — technically empty but on the market. Others serve as secondary residences used occasionally. The ones that make headlines are the 3.85 million long-term vacant properties with no clear market purpose: nobody is selling them, renting them, or using them. These are the akiya that municipalities are trying to deal with.

Akiya vs kominka vs machiya

These three terms overlap but mean different things. Understanding the distinction helps when browsing listings or talking to agents.

A kominka can be an akiya if it's unoccupied. A machiya can be an akiya if nobody lives there. The terms describe different things: akiya describes occupancy status, while kominka, machiya, and kodate describe the type of building.

Why are there so many akiya?

Japan's akiya problem comes down to a collision of forces: a population that peaked in 2008 and has been shrinking since, young people leaving rural areas for cities, a cultural preference for new-build houses over used ones, a tax system that makes demolition financially painful, and a construction industry that keeps building 800,000+ new homes per year despite declining demand.

The result is a country with more houses than it needs — and the gap is widening every year. For the full breakdown, see Why Does Japan Have 9 Million Empty Houses?

Can foreigners buy akiya?

Yes. Japan places no restrictions on foreign property ownership. Any foreigner can buy an akiya regardless of nationality, visa status, or residency. You don't need to live in Japan, speak Japanese, or hold any particular visa. The legal framework is the same for foreign and Japanese buyers.

That said, owning an akiya does not give you the right to live in Japan — you still need a separate visa for that. And the buying process involves Japanese-language contracts, a judicial scrivener for registration, and tax obligations that apply even if you live abroad.

Where to find akiya

The main channels are akiya banks (空き家バンク) — municipal databases run by local governments — and standard Japanese real estate platforms like SUUMO, at home, and LIFULL HOME'S. Akiya banks are mostly in Japanese, fragmented across hundreds of municipal websites, and often hard to navigate.

The Akiya Labs directory aggregates 730+ akiya banks across all 47 prefectures into one searchable index — the largest English-accessible collection available.
