TOKYO – When Mr Jaya Thursfield found a house he wanted to buy in Japan a few years ago, friends and family told him to forget it.

The place was not worth the trouble, they said.

After all, it stood in a forest of shoulder-high weeds after being abandoned about seven years earlier – one of the millions of vacant houses known as akiya, Japanese for “empty house” – throughout the country.

But Mr Thursfield, 46, an Australian software developer, was not deterred.

Through the overgrown garden, he could see that it was special: The black roof tiles cascaded down to slightly curving eaves that were much higher off the ground than those of most houses.

The entrance hall had its own gable tile roof. If the 251 sq m house looked more like a Buddhist temple than a farmhouse, it is because it was built by a temple architect in 1989.

Mr Thursfield and his Japanese-born wife, Ms Chihiro, had moved to Japan from London in 2017 with their two young sons and a dream of buying a home with a big yard.

The plan was to purchase a vacant lot and build a house on it, but land is expensive in Japan and their budget would not allow it. So, they turned to the growing supply of abandoned houses, which are cheaper and often come with more land.

They are far from the only ones.

“We would never have been able to afford a house of this quality and size if it wasn’t an akiya,” Ms Chihiro Thursfield, 49, said.

“And while many Japanese don’t like used homes, foreigners see a house that is cheap and are more willing to reuse and renovate to their tastes and budget.”

As Japan’s population shrinks and more properties go unclaimed, an emerging segment of buyers, feeling less tethered to overcrowded cities, is seeking out rural architecture in need of some love.

The most recent government data, from the 2018 Housing and Land survey, reported about 8.5 million akiya across the country – roughly 14 per cent of the country’s housing stock – but observers say that there are many more today.

The Nomura Research Institute puts the number at more than 11 million, and predicts that akiya could exceed 30 per cent of all houses in Japan by 2033.

The Thursfields’ house, which sits among the paddies in southern Ibaraki Prefecture, about 45 minutes from central Tokyo, had been deserted after the previous owner’s family refused to inherit it upon the owner’s death.

The local municipality took over the property and put it up for auction with a 5 million yen (S$50,000) minimum bid, but it failed to sell.

When it landed on the block again, Mr Thursfield decided to try his luck. After giving it a quick inspection with an architect friend and finding no major issues despite the years of neglect, he nabbed the house for 3 million yen.

Houses in Japan typically decrease in value over time until they are worthless – the cultural legacy of post-World War II construction and shifting building codes – with only the land retaining value.

Owners feel little incentive to maintain an ageing house and buyers often seek to demolish them and start fresh. But that can be expensive.

Others aim to preserve what is there.

“There was no way we wanted to knock it down and build something new. It was too beautiful. So, we decided to renovate instead,” the Thursfield family said.

“I’ve always been someone who likes to jump in the deep end, take a few risks and learn new things, so I was confident that we would manage somehow.”

Since buying the farmhouse in 2019, the couple has spent about US$150,000 on renovations, and there is more to do. The Thursfield family has documented the project on YouTube, drawing more than 200,000 subscribers.

While the Thursfields’ house had been abandoned by the previous owner’s heirs, some home owners died without ever naming an inheritor.

Others leave their properties to relatives who refuse to sell family land out of respect for their elders, leaving the house to wither.

“In rural areas, there is a long history of ancestral owners of akiya living in the houses and on the land,” said Mr Kazunobu Tsutsui, a professor of rural geography and economics at Tottori University who lives in a renovated akiya built more than a century ago.

“Therefore, even after moving to the city, families will not give up their akiya easily.”

Now, officials on both local and national levels are taking steps to give them a push.

“Poorly maintained akiya can mar the scenery as well as endanger residents’ lives and property if they collapse,” said Mr Kazuhiro Nagao, a city official in Sakata, along the west coast, where heavy snowfall can damage unattended structures.

“We’re partly subsidising demolitions, collecting neighbourhood association reports on akiya and trying to make owners aware of the problem by holding briefings”.

Akiya are increasingly seen not just as a threat to suburban and rural markets but to the emotional health of the country, sparking family disputes over inherited properties.

That, in turn, has led to a cottage industry of akiya consultants like Mr Takamitsu Wada, chief executive of Akiya Katsuyo, who acts as a counsellor for squabbling relatives, often urging them to act before their properties become a lost cause.

“In many cases, the parents die without making clear their wishes regarding the family home, or they develop dementia and find it difficult to discuss these things,” Mr Wada said.

“In such cases, the children may feel guilty about getting rid of the family home and may often choose to leave it unoccupied.”

Municipalities across Japan are also compiling listings of vacant houses for sale or rent.

Known as “akiya banks”, they are often bare-bones webpages with a few underwhelming photos.

Some have partnered with companies like At Home, which currently lists akiya in 658 of Japan’s 1,741 municipalities.

“Akiya banks are run by municipal office workers, the majority of which often do not have any experience in real estate,” said Mr Matthew Ketchum, a Pittsburgh native and co-founder of Akiya & Inaka, a Tokyo-based real estate consultancy.

“The existing solutions do not align with the needs of modern buyers and sellers.” Mr Ketchum’s firm is one of several that have sprung up to capitalise on the akiya glut, matching vacant homes with curious buyers.

Akiya & Inaka’s listings include a 204 sq m home built in 1983 in the suburb of Hachioji, Tokyo, with a small garden and a reception room featuring a raised tatami floor, tokonoma alcove and a rare wickerwork ceiling of woven cedar. The property is listed at 36 million yen.

“Every Japanese agent we talked to advised us to demolish this place,” said the house’s owner, Takahiro Okada, 85, a retired journalist.

He and his wife, Reiko, 86, had been renting out the house but decided to sell after their tenant left in 2022.

Their children were not interested in it, so the property lingered. Different owners might have torn it down and sold the land.

“If we all do that, we’re losing Japanese culture,” Ms Reiko Okada said.

“When seen from an international perspective and through the eyes of foreigners, Japanese things can have inherent uniqueness and value.” Mr Ketchum and his partner, Parker J Allen, said that they are now fielding about five times the number of inquiries compared to when they began in 2020.

“At first, we were getting most of our inquiries from Japan residents, Australians and Singaporeans,” Mr Ketchum said.

“That has changed now, with the vast majority of our international clients being based in the United States.”

”Many clients have been spurred by the pandemic, which definitely changed the mindset of people living in Japan regarding the idea of rural living,” Mr Allen said.

“The fact that property in the Japanese countryside is by and large undervalued and there are viable properties that are almost turnkey has finally dawned on these people.”

One person it did not dawn on recently is Mr Alex Kerr, an author and Japanologist originally from Maryland, who became an akiya owner in 1973 when he acquired an abandoned country house (known as a minka) in the mountains of Shikoku, the smallest of Japan’s four main islands, for US$1,800.

Named Chiiori, or House of the Flute, the thatched-roof aerie is about 300 years old.

Inside, it is a shadowy space of polished wood floorboards, a large sunken irori hearth and giant overhead rafters wreathed in smoke.

Outside, mist rises from the Kumatani River in the gorge below.

Mr Kerr, 70, is the first to admit that akiya can be money pits.

He has spent decades and roughly US$700,000 (about half of which came from a government grant, he said) maintaining it, and now rents it out as a guest house.

It is one of about 40 derelict Japanese properties he has restored over the years, all the while preaching the importance of conservation and rural revitalisation to municipalities, companies and home owners who may not know what makes their properties special.

“Many cultures have wooden architecture, but when it comes to the techniques of carpentry, Japan overwhelmingly leads the world in joinery and use of materials, as well as use of space and choreography,” said Mr Kerr, whose books include the memoir Lost Japan.

“When it comes to old minka houses, you have all that, set in a natural environment, and within the context of being cheap. In the Cotswolds, wooden houses cost a fortune, but in Japan they’re being thrown away.”

But he has taken note as real estate companies have begun to snap up habitable antique houses and market them to non-Japanese luxury buyers.

He also pointed to young international buyers opening Airbnb rentals in erstwhile akiya and attending events like minka conferences. NYTIMES
