In the suburban neighborhood of Midorigaoka, about an hour by train outside Kobe, Japan, all the houses were built by the same company in the same factory. Steel frames fitted out with panel walls and ceilings, these homes were clustered by the hundreds into what was once a brand new commuter town. However, they were not built to last.
Daiwa House, one of the biggest prefabricated housing manufacturers in Japan, built this town in the 1960s during a postwar housing boom. It is not unlike the suburban subdivisions of the Western world, with porches, balconies and rooflines that shift and repeat up and down blocks of gently curving roads.
Most of those houses built in the 1960s are no longer standing, having long since been replaced by newer models, finished with fake brick ceramic siding in beiges, pinks and browns. In the end, most of these prefabricated houses — and indeed most houses in Japan — have a lifespan of only about 30 years.

Unlike in other countries, Japanese homes gradually depreciate over time, becoming completely valueless within 20 or 30 years. When someone moves out of a home or dies, the house, unlike the land it sits on, has no resale value and is typically demolished.
This scrap-and-build approach is a quirk of the Japanese housing market that can be explained variously by low-quality construction to quickly meet demand after World War II, repeated building code revisions to improve earthquake resilience and a cycle of poor maintenance due to the lack of any incentive to make homes marketable for resale.
In Midorigaoka, even the newer homes built in the 1980s and 1990s are nearing the end of their expected lifespan. Under normal circumstances, their days might be numbered.
Like Daiwa House, many other big housing manufacturers are getting into the refurbishing business. A 45-minute drive north of Tokyo, the nation’s largest prefab builder, Sekisui House, operates a home park featuring its newest models.
Most cater to the high end of the market, with large multistory layouts and luxury finishings, but tucked in a corner is a more modest two-story house. The first floor is furnished like a typical home built in the 1980s: small rooms, highly compartmentalized spaces and even a recliner in the living room. Upstairs, the same floorplan has been updated so that the kitchen opens out onto the dining area and walls are pushed back or removed altogether. A traditional tatami mat sitting room in the old layout becomes a media room, with a low couch and a flatscreen television.
REMODELING
For the company, these simple renovations can turn a vacant home into a new sale.
“If we can remodel these old houses, their value will not decrease to zero and we won’t have to demolish them,” said Kenichi Ishida, a managing officer at Sekisui House. “Nowadays young people don’t have much money, so they won’t hesitate to buy older buildings.”
In Takatsuki, halfway between Osaka and Kyoto, that economic reality is evident.
“Many of the younger generation around my neighborhood live in renovated homes,” one 39-year-old resident said.
He lives in a renovated Sekisui House with his wife and two young children, and notes that the price of a renovated home was much lower than that of a new one.
“We want to save money for taking care of our kids and parents,” he says. “For us, the renovated home located close to my parents’ home has much higher value than a newly built home that is far away.”
It is not just the big housing manufacturers that are catching on.
Zoe Ward is a Tokyo real-estate agent and CEO of Japan Property Central, which specializes in finding homes for expats, and she says buyers are starting to reconsider the value of older buildings.
New companies have opened in recent years that focus specifically on refreshing old spaces.
“Sometimes they’ll gut the entire building to its concrete shell,” she said. “The outside won’t look any different from the buildings around it, but inside it’ll look like a brand new house.”
As demand for housing grows in Tokyo, renovation companies are on the lookout for people ready to sell.
“We get them calling every day,” Ward said.
Renovation is not always an option.
In the Tokyo suburb of Tachikawa, Shiro Kawashima and his wife, both middle-aged, are walking through a faux neighborhood lined with model homes. Built by prefabricated-housing manufacturers and local carpenters, the homes are on display and available for tours guided by eager salespeople. The couple, who live nearby, are here shopping for a new home, albeit reluctantly.
“I’m really proud of my old house,” he said. “It’s regrettable, but I have to tear it down.”
The house is 70 years old — a rarity — and suffering from structural damage that is prohibitively expensive to fix, he said.
Moving is also out of the budget, so his only option is to tear the old house down and build anew. The houses on display here do not appeal to him.
“Not at all,” he said.
“I just want a simple, basic structure,” he said.
Like his current home.
Younger people, particularly in urban areas, have more flexible options. To accommodate them, new companies are looking beyond conventional housing. In recent years, a number of small development companies have been buying up older buildings and giving them new uses.
Tokyo-based ReBITA has been converting apartment buildings, offices and company dormitories into shared live-work spaces — affordable rental units with common kitchens and work areas.
Such spaces were uncommon in Japan just five years ago, said Azby Brown, director of the Kanazawa Institute of Technology’s Future Design Institute in Tokyo.
“It’s a new lifestyle and I don’t think a lot of the big housing companies have picked up on it yet,” he said.
Brown said it is as much about reducing the cost of housing as embracing a more community-oriented form of living. Some even see these types of social space as a roundabout way to reverse the nation’s low birth rate.
In the face of Japan’s demographic trends, the Tokyo Metropolitan Government is doing its own bit of social engineering as it focuses on refurbishing the mid and high-rise apartment buildings that rose across the city during the 1960s and early 1970s.
To give new life to these buildings, the capital is encouraging families with small children to move in by prioritizing their applications. It is also helping people to qualify for housing slots if they choose to live close to their elderly parents.
“All of these efforts are related to dealing with our aging society,” said Hiroyuki Ebina, a director of planning and housing in the Bureau of Urban Development.
However, it is not just about freshening up the resident pool. The buildings in question are often maintained through tenant associations, and as older tenants die, there is less money for upkeep and earthquake retrofits.
To inject more contributions to those efforts, the national government’s Urban Renaissance Agency is trying to lure younger people into these buildings.
One approach is by partnering with the minimalist retailer Muji. As well as being a global presence, the Japanese brand retains considerable cachet in its home country, where its simple, utilitarian products are widely popular.
Through its association with the Urban Renaissance Agency, Muji has begun renovating and redecorating units in public housing blocks to attract younger tenants — tearing out walls, replacing clunky kitchen cabinets with open storage spaces and racks, clearing space for bicycle storage.
“The old design doesn’t fit with younger people’s tastes,” Muji’s dwelling space operation director Koji Kawachi said, adding that many of the buildings have a cramped, overly partitioned layout.
“The renovation is based on the idea that small, separated rooms can be integrated into larger spaces,” he said.
The company strips the rooms of excessive finishes and replaces them with clean white surfaces and spare wood furnishings. The he Muji units receive five to seven times as many applications as typical units, he said.
The company has completed more than 500 renovations so far and plans to continue with 150 to 200 units per year. With more than 750,000 housing units under its purview, the Urban Renaissance Agency has scope to experiment.
As Japan’s population shrinks and shifts, the demand for space has become increasingly uneven, which has left many small and mid-sized cities in a state of slow decline.
The southern city of Kitakyushu, a former steel city, has seen its population growth fall 1.5 percent. It is just an hour by train from Fukuoka, the startup capital of Japan and the fifth-largest city in the nation, which has seen a population influx due to strategic tax incentives and foreign resident immigration reforms. However, while Fukuoka is booming, Kitakyushu is emptying out.
For Mitsuhiro Tokuda, the decline was particularly evident in the city’s downtown area, a compact network of narrow commercial streets and large shopping arcades.
Tokuda, a professor of architecture at the Kyushu Institute of Technology, launched a study of downtown Kitakyushu to quantify how much of the city had become vacant. With a team of students, he conducted a detailed survey to identify which buildings were partially or completely vacant and which could be reused.
“But thinking can’t change anything,” he said.
REVIVAL
So he started a small business to work with property owners to renovate vacant spaces for new uses. Their first product took a vacant 5th floor and converted it into shared office spaces now used by graphics designers and video editors.
Tokuda walks through the ground floor of a mid-rise building near the center of Kitakyushu’s downtown. A former clothes factory, it had long been empty.
Tokuda and his team converted it into a hodgepodge of new spaces — a community room, small offices, creative work spaces for local craftspeople, a cafe and various boutiques. One features vintage paperback books. Another display window holds a pair of leopard-print loafers. Almost all of the spaces are now rented out.
Nearby is Mizutama Shokudo, a restaurant in a renovated space.
“We like old buildings, so when we started our business, we looked for an old property from the beginning,” co-owner Yuka Ishikawa said. “We liked the fact that this building is not facing a busy main street and it’s in the peaceful, old-style shopping neighborhood.”
There are some downsides to older buildings, she said.
Rain sometimes leaks through its old roof and a recent fire next door partially burned some of the wood structure.
However, it is part of the character of the space and works alongside the theme of the restaurant, which serves “mother’s home cooking-style” meals, she said.
“By serving that kind of meal in this old building, we would like to keep conveying the beauty of old things that have been cherished by people for a long time,” she added.
Tokuda said he saw a bigger potential for this type of building reuse and wanted to teach others to try it for themselves.
In 2011, he launched what he calls a Renovation School in which students — architects, designers and businesspeople, mostly — develop business plans for reusing vacant space. It is a crash course, and over one week teams identify vacant spaces, survey local needs and create plans. On the final day, they pitch their plans to the property owners.
The school has resulted in dozens of projects, Tokuda said. Renovation Schools have now been conducted in cities across Japan, creating new retail spaces, hotels, cafes and apartments out of once-vacant buildings.
The impact is easy to see in Kitakyushu. Walking down a commercial street, Tokuda points to four different buildings on one block that have been reused or redeveloped through the Renovation School. The property owners and businesspeople have even formed an association that raised funds to relandscape the street.
Cracked asphalt on the narrow street has been replaced with square concrete paving stones, their varying shades of grey laid out like a long mosaic. Streetlights have been painted bright green and some shopkeepers, like those running a bar inside an old shipping container, have added benches and seating outside for public use.
Tokuda said this approach to reusing space can be a kind of catalyst for change.
“By stimulating the building, we can stimulate the neighborhood,” he said. “It’s a form of town renovation.”
Ishikawa said renovated buildings like hers represent hope for the future in Kitakyushu.
“We want to create a new cycle of ‘live in the town, work in the town and patronize the businesses in the town,’” she said.
The gutting of Voice of America (VOA) and Radio Free Asia (RFA) by US President Donald Trump’s administration poses a serious threat to the global voice of freedom, particularly for those living under authoritarian regimes such as China. The US — hailed as the model of liberal democracy — has the moral responsibility to uphold the values it champions. In undermining these institutions, the US risks diminishing its “soft power,” a pivotal pillar of its global influence. VOA Tibetan and RFA Tibetan played an enormous role in promoting the strong image of the US in and outside Tibet. On VOA Tibetan,
There is much evidence that the Chinese Communist Party (CCP) is sending soldiers from the People’s Liberation Army (PLA) to support Russia’s invasion of Ukraine — and is learning lessons for a future war against Taiwan. Until now, the CCP has claimed that they have not sent PLA personnel to support Russian aggression. On 18 April, Ukrainian President Volodymyr Zelinskiy announced that the CCP is supplying war supplies such as gunpowder, artillery, and weapons subcomponents to Russia. When Zelinskiy announced on 9 April that the Ukrainian Army had captured two Chinese nationals fighting with Russians on the front line with details
On a quiet lane in Taipei’s central Daan District (大安), an otherwise unremarkable high-rise is marked by a police guard and a tawdry A4 printout from the Ministry of Foreign Affairs indicating an “embassy area.” Keen observers would see the emblem of the Holy See, one of Taiwan’s 12 so-called “diplomatic allies.” Unlike Taipei’s other embassies and quasi-consulates, no national flag flies there, nor is there a plaque indicating what country’s embassy this is. Visitors hoping to sign a condolence book for the late Pope Francis would instead have to visit the Italian Trade Office, adjacent to Taipei 101. The death of
By now, most of Taiwan has heard Taipei Mayor Chiang Wan-an’s (蔣萬安) threats to initiate a vote of no confidence against the Cabinet. His rationale is that the Democratic Progressive Party (DPP)-led government’s investigation into alleged signature forgery in the Chinese Nationalist Party’s (KMT) recall campaign constitutes “political persecution.” I sincerely hope he goes through with it. The opposition currently holds a majority in the Legislative Yuan, so the initiation of a no-confidence motion and its passage should be entirely within reach. If Chiang truly believes that the government is overreaching, abusing its power and targeting political opponents — then
