Japan Long Looked Down at Luxury Penthouses. Now Things Are Looking Up.

Once considered an ostentatious display of wealth, extravagant top-floor spaces are suddenly in demand

Ken Akao, a 35-year-old cosmetic surgeon, was a little concerned when he bought a multimillion-dollar Tokyo apartment in October 2023. It wasn’t about the property itself, a three-bedroom, 39th- floor penthouse with a spiral staircase, Jacuzzi and infinity pool. It was about what his father, a frugal Japanese diplomat of the old school, would think after seeing a property so grand—and so un-Japanese.

After some time, Akao summoned the courage to invite his dad for a visit. To his relief, he says, the elder Akao enjoyed the tour and pronounced the pad “wonderful.”

A century after the Park Avenue penthouse became established as the height of residential luxury for New Yorkers, the concept has finally made it across the Pacific to Tokyo. Part of the credit goes to people with foreign experience such as the younger Akao, who grew up largely overseas, as well as the influence of Chinese buyers flooding into Japan these days.

It also reflects changing values about what constitutes the ideal property in Tokyo.

Japan’s capital first flourished in the 17th century as the seat of the shogun, or generalissimo, who reigned as Japan’s de facto ruler. The Tokugawa family of shoguns, having subjugated feudal lords across the land, insisted that the lords spend half their time in the capital. Soon the city then known as Edo was dotted with spacious compounds where grandees lived in sprawling low-slung wooden homes watched by the shogun’s spies.


Long after Edo became Tokyo and feudalism ended in 1868, those properties served as the prototype for the rich. Kakuei Tanaka, a poor man from the provinces who got wealthy with business ventures while rising to become Japan’s prime minister between 1972 and 1974, used to hold court inside the walls of a leafy compound in the Mejiro area of Tokyo, where he could feed the carp in his pond. (The house was destroyed by fire on Jan. 8. No one was hurt.) In a country that tends to frown on ostentation and special treatment for the privileged, the high walls surrounding such properties offered privacy.

These days, most rich Japanese still prefer to keep their wealth under wraps. But other changes have made a luxury condominium in a prime central Tokyo location look attractive compared with a house on a spacious property in a residential area.

One is the burst of the land-price bubble in the early 1990s, which shattered the myth of land as an indestructible store of value. These days, say real-estate professionals, bankers are less inclined to insist on land as collateral and more willing to extend loans backed by quality condos that are seen as likely to retain value across economic cycles. Also, in an ageing country where labor is in short supply, many older couples look askance at trying to care for large grounds. “Weeding is such a pain for old people,” said Satoshi Omori, president of a Tokyo real-estate appraisal firm.

The 2011 earthquake in northeastern Japan boosted the appeal of living in an earthquake-resistant concrete building in a central location rather than a wooden house farther out, where services might be hard to come by in an emergency.

“Compact cities are a global trend and people tend to prefer places that are more convenient,” said Shigeru Funabashi, a Tokyo broker.

Funabashi is a cosmetic surgeon who has in recent years shifted his career toward real estate, having developed a fascination with luxury residences. In 2011, he went to London to take a look at One Hyde Park, which is the location of a penthouse that was recently one of the highest priced in the city. He recalls thinking to himself, “Something like this will come to Tokyo someday.”

Foreign developers were ahead of the game in tapping the wellspring of demand Funabashi sensed and spreading the word “penthouse” in the Japanese language. In the Shibuya district, popular among tourists, Canadian developer Westbank in 2020 completed a five-floor condominium designed by architect Kengo Kuma. Traditionally, such buildings had nothing fancier on the top floor than plumbing and electrical equipment. But Westbank put in a multilevel penthouse with a private infinity pool on the roof. It sold early last year for $50 million, according to the developer.

Some other buyers in the building bought two units to combine them. “It really showed us that there is this massive gap in the market for products at this level,” a Westbank representative in Japan said. She said that if Westbank had the chance to build the 12-unit property again, it would make it with only six units.

Marq Omotesando One is another luxury low-rise condominium by foreign developers in central Tokyo that was completed in 2021. The development, led by a unit of Hong Kong-based investment firm BPEA, features a 6,700-square-foot penthouse with roof pool that local agents said has been listed at a price in the tens of millions of dollars. Its current status couldn’t be determined.

At Japanese real-estate development companies, “no one really wanted to rock the boat or do anything different,” said Zoe Ward, a real-estate agent originally from Australia who has worked for 15 years in Japan’s property market. But they changed course after seeing foreign developers building extravagant properties and selling units at high prices never seen before, Ward said.

Japanese developers say that many customers of ultra expensive condos are locals, including corporate executives and younger entrepreneurs who are often familiar with high-end homes in places such as New York and London.

Azabudai Hills, a Mori Building project in central Tokyo that includes offices and apartments, opened on Nov. 24. The development includes what is currently the tallest building in Japan, with 91 Aman-branded apartments on high floors. Planning documents submitted to authorities show there are three duplex penthouse units on the 64th floor. The largest unit occupies half the floor and has a private pool, the documents indicate. Local brokers say all three have been sold.

Mori Building declined to release floor plans or price ranges for those apartments—a reminder that the rich here still don’t want their private business aired, even if their high-rise homes are visible dozens of miles away. A local publication, Daily Shincho, reported that the largest unit sold for the equivalent of $200 million, which would make it the highest-price condo ever sold in Japan by a multiple of two or three.

Swimming pools on rooftops are rare in Japan, partly because of concerns about water leaking during earthquakes. But that is also changing. A central Tokyo office-hotel building developed by Mori Building opened in October with restaurants and an infinity pool on the roof.

“The rooftop was never utilised in Japan as much as it should be,” said architect Shohei Shigematsu, who designed the building. He said his team added extra drainage to reassure the developer that water wouldn’t splash on passersby 49 floors below in the event of an earthquake.

More luxury penthouses are on the way, including several on the top floor of a 13-story building at Mita Garden Hills, a project jointly developed by units of Mitsui Fudosan and Mitsubishi Estate. The building won’t be completed until 2026, but Mitsui says all of the penthouses have been sold.

The most expensive one, with a floor area of about 4,000 square feet, sold for 5.5 billion yen, equivalent to about $38 million, according to a broker familiar with the deal. Mitsui declined to comment.

In Osaka, the centre of Japan’s second-largest urban area after the Tokyo region, a penthouse in a 46-storey building, due to be completed in December 2025, is listed for the equivalent of about $17 million. The price for the unit, which at 3,300 square feet is the building’s largest, would be the highest price ever for an Osaka-area condo, said a spokesman for Sekisui House, one of the developers.

The spokesman said the penthouse has the vibe of a European guesthouse for visiting dignitaries, with chandeliers hanging from ceilings that are as high as 16 feet. Some other units feature an elevator to carry the owner’s car into the premises.

While ultrahigh-price deals are usually not included in industry databases, prices of Tokyo apartments generally are rising, driven by the higher cost of materials and labor. The Real Estate Economic Institute, a Tokyo-based firm tracking the property market, said the average price of a new apartment sold in central Tokyo for the six months through September was up 36% compared with the same period a year earlier and topped 100 million yen, equivalent to about $700,000, for the first time.

Akao, the cosmetic surgeon and recently minted penthouse owner, says he grew fond of the luxury lifestyle when visiting Aman hotels in Japan and Greece. He wasn’t able to get his hands on one of the Aman units in Azabudai Hills, but found a good substitute in his penthouse across from Yoyogi Park, a central Tokyo urban oasis like New York’s Central Park.

There is an en-suite bathroom in the primary bedroom, rare for a Japanese home, and Miele appliances in the kitchen. The staircase from the living-dining area, which features sofas from Arflex Japan, leads to an open-air 700-square-foot deck with the infinity pool.

“I often have large group get-togethers,” Akao said. “The pool will make gatherings easier.”

Akao said that growing up in the U.S., Switzerland and Austria where his father was posted made him familiar with the lifestyle because some of his classmates lived in houses with a pool and talked about it casually at school.

While analysts say most of the recently built penthouses are bought by people who intend to live in them, there are still flippers. Akao might be one of them. He said he is trying to sell his unit before considering whether to move in. He declined to disclose what he paid but said he was asking the equivalent of about $9 million.

The ball is in the buyer’s court with this knockdown/rebuild opportunity

Tue, Apr 18, 2023 2 min

Glenhaven in Sydney’s Hills District is one of those areas that locals tend to keep to themselves. Leafy with large blocks on offer, the suburb takes its name from its valley location, with the northern end originally known as the Glen and the southern end called the Haven. 

En route from Parramatta to the Hunter, Glenhaven has become an ideal place for growing families in search of a little more space, or even room to house several generations under one roof.

The challenge is finding properties that tick all the right boxes.

As demand for trades and supply chain issues continue to ease, now could be the right time for a knockdown/rebuild project for would-be buyers looking to create their dream home.

Fairmont Homes specialises in knockdown/rebuild projects in Sydney. General manager at Fairmont Homes, Daniel Logue, said there are key features to look for when choosing a knockdown/rebuild site.

“The key items we look for are the site falling to the street, not to the rear, to help with stormwater drainage as well as access to the site,” he said. “Neighbouring property front setbacks are also important. In some older areas, the older houses are set closer to the street, meaning your new home will have to be set to suit.

“Value for money and the return on the end sale price of the home is another issue.”

If possible, he said designing a home that meets the criteria of the Complying Development legislation will speed up approvals considerably.

While suitable knockdown/rebuild sites can be hard to find in Glenhaven, there are still hidden opportunities if you know where to look.

One block at 158 Gilbert Road, Glenhaven is ideally suited for rejuvenation. With almost 850sqm to play with, it slopes down to the street and sits between neighbouring properties that have already been stylishly updated.



An existing basketball court at the rear could provide the perfect teen backdrop to a family home, or it could make way for a larger house with landscaped gardens and pool. Alternatively, it could be the perfect position for a cabana or granny flat to serve as in-law accommodation or a source of secondary income.

With recent sales of completed homes in nearby streets reaching well above $5 million, it’s a great opportunity to make a slam dunk of a buy into one of Sydney’s best kept secrets.

Address: 158 Gilbert Road, Glenhaven
Price guide: $1.8 million
Inspection: By appointment only
