Japan's Empty Homes Are Becoming a Side Hustle Gold Mine

Japan is sitting on nine million empty homes, and a new wave of young buyers wants them. These vacant properties, called akiya, are often sold for the price of a used car in regional towns, and a growing community of foreign renovators is turning them into short-term rentals, guesthouses, and design-forward Airbnbs. Japan's Empty Homes are no longer just a demographic warning sign — they are becoming a business model, a content niche, and for some, a full-time job.

The math is easy to see. Anton Wormann, a Swedish renovator known online as Anton in Japan, bought an abandoned 86-year-old house in Tokyo for around fifty-four thousand dollars and spent roughly another fifty-six thousand on renovations, according to documents reviewed by CNBC Make It. After a fifteen-month rebuild, the property now rents for about five hundred dollars a night and generates roughly eleven thousand dollars in monthly income. He has since scaled up to eight properties in Japan, seven of which were previously abandoned homes, with three renovations finished and four more underway.

Why Japan's Empty Homes appeal to young renovators

The supply is staggering. Japan's national statistics bureau counted a record number of vacant dwellings in its 2023 housing survey, driven by a shrinking population, inheritance tangles, and decades of urban migration. Where American or European buyers see a housing crisis, some younger buyers see an entry point: a traditional wooden kominka with cedar beams, tatami rooms, and a veranda can cost less than a down payment on a city condo back home. Online communities on Reddit and YouTube channels like Tokyo Llama have made the process visible step by step, demystifying contracts, local contractors, and renovation timelines.

Local governments are actively recruiting these buyers. Most prefectures run an "akiya bank," an official listing portal where owners submit vacant properties they want to sell or lease, according to coverage in the Ise Shimbun of a resident-led restoration project in Mie Prefecture that drew three hundred visitors to a neighborhood market in October 2026. Many municipalities sweeten the deal with renovation grants — some worth up to two million yen — plus relocation subsidies for younger families willing to settle in, as reported in a 2026 akiya buyer's guide. Japan's Empty Homes, in other words, come with a welcome package.

The math behind the makeover

Costs vary wildly, but the range is documented. A basic livability upgrade — roof repair, plumbing, electrical, and a modern bathroom — can run two to five million yen for a modest rural home, while a full renovation of a large kominka can cost ten to fifteen million yen or more, according to the buyer portal Cheap Japan Homes. Even at the high end, purchase plus renovation often lands well under one hundred fifty thousand dollars total, a figure nearly impossible to match in markets like New York, London, or Sydney. Short-term rental demand helps close the gap: Wormann's Tokyo listing is reportedly booked nearly three months out, and AirROI market data from September 2026 shows top-quartile Airbnbs in Osaka's Naniwa Ward clearing around one hundred sixty thousand yen a month after running costs.

That income profile is what turned a hobby into a career. Wormann now works with real estate clients in Japan, advising on properties where thoughtful renovation can add value, according to Metropolis Japan. His playbook — preserve traditional architectural details, add modern comforts like updated kitchens and underfloor heating, and rent to design-conscious travelers — has been copied by a wave of imitators documenting their own akiya projects online.

The risks nobody posts about

Not everyone should copy the playbook, and the veterans say so loudly. Wormann told Metropolis Japan that none of his real estate clients are currently buying rural akiya, because such properties can carry significant structural, legal, and redevelopment risks. Termite infestations, unclear title chains, and aging electrical systems can double a renovation budget, and rural listings may sit hours from the nearest train station with limited resale demand. "I would not invest in something in the countryside unless you have the time to fix it up or you are treating it as a lifestyle investment rather than expecting a monetary return," he said in the same interview.

The legal landscape is tightening too. Japan's revised Special Measures Act on Vacant Houses pressures owners of neglected properties to sell, demolish, or maintain them — which pushes more akiya onto the market at lower prices, but also means some listings are being sold under regulatory pressure rather than priced as bargains. And foreigners still face practical friction: most akiya banks operate only in Japanese, contracts follow local custom, and building codes require certified contractors for structural work. Success stories tend to share one trait, as Wormann put it: "You have to be passionate about it and you have to spend time in the area." The buyers who treat Japan's Empty Homes as community projects tend to win; the ones chasing a quick flip, he warns, usually lose.

Still, the trend is reshaping how a generation thinks about housing. When a home can cost less than a car, the question stops being whether you can afford property and becomes whether you are willing to learn a new language, live in a small town, and swing a hammer. For the renovators posting from rural Japan, the answer is increasingly yes — and the future of travel may look less like a hotel booking and more like a house you own. For anyone weighing a similar move, Airbnb's latest hosting rule changes are worth reading before listing anything.
