The 'Lost 30 Years' Are Over—4 Contrarian Signals from Tokyo Real Estate

The overwhelming excess of demand has long been the primary formula for explaining Tokyo's residential market. In a megacity where jobs and opportunities are concentrated, rising home prices have been seen as a perfectly natural economic consequence and a sign of urban growth. However, recent changes in the Tokyo condominium market show that this classic formula is no longer working as it used to. While home prices are soaring to record highs day after day, the influx of people who support the city is noticeably decreasing. This is not just a temporary market adjustment, but a strong signal that the residential structure of Tokyo and the map of the metropolitan area are fundamentally changing.

In 2025, the average price of new condominiums in Tokyo's 23 wards jumped 21.8% year-over-year to 136.13 million yen. In particular, the average price in the six central wards soared 20.2% in one year to 195.03 million yen, approaching the 1990 peak of 226.62 million yen when the real estate bubble was at its height. What we need to pay attention to here is the psychological pressure of the absolute price rather than the simple rate of increase. Whereas in the past, Tokyo housing prices remained within a realistic range that could be reached through diligent work and savings, current prices have become an immediate barrier that pushes the middle-income class out of the market altogether. With the pace of income growth unable to keep up with the rise in asset prices, once the price barrier exceeded a certain threshold, buyers did not give up but instead turned to the outskirts of the metropolitan area.

Recent population movement statistics released by the Japanese Ministry of Internal Affairs and Communications prove this change with concrete figures. In 2025, the net inflow of population into Tokyo was 65,219, a decrease of 14,066 from the previous year, marking the first time the increase has slowed in four years. What is more noteworthy is that the net inflow into the 23 central wards plummeted by 19,607 from the previous year to 39,197. This suggests that the criteria for choosing a place to live have completely changed. An interesting point is that Saitama, Kanagawa, and Chiba prefectures, which are adjacent to Tokyo, are absorbing Tokyo's population and emerging as new centers. Saitama Prefecture saw a net inflow of 22,427, an increase of 691 from the previous year, and Kanagawa Prefecture also had a net inflow of 28,052, an increase of 1,089. This should be interpreted not as a phenomenon of people leaving Tokyo entirely, but rather as a phenomenon where people are giving up or postponing entry into the city center, blocked by Tokyo's high price barrier.

This move is not simply due to a lifestyle change favoring a more pleasant environment. It is the result of a thorough calculation of economic benefits. Housing purchase costs have already exceeded what households can afford, and the accompanying surge in rent is eroding disposable income and taking away the余裕 of life. In December 2025, the average monthly rent for a studio apartment in Tokyo's 23 wards was 106,854 yen, an increase of about 10,000 yen in one year, reaching the highest level since 2015. Even young people and high-income newlyweds, who in the past would have insisted on entering the city center even if it meant overstretching themselves, are now finding a practical compromise between commuting time and housing costs. It is not that Tokyo's urban appeal has diminished, but that its cost structure has completely deviated from a reasonable range that ordinary citizens can endure, transforming it into a space for a select few.

Ultimately, condominiums in central Tokyo are completely changing in character, becoming not a universal residence that anyone can dream of, but a class asset occupied and traded only by a specific class. The city center is solidifying as a space for investment and asset preservation, and the center of gravity for actual residence is gradually shifting to the outskirts, accelerating the phenomenon of polycentricity where the entire metropolitan area is divided into several hubs. The Tokyo Metropolitan Government has proposed a plan to supply affordable rental housing by easing floor area ratios, but this is more of a stopgap measure to mitigate the ill effects of unipolar concentration. Today's Tokyo is not just a dangerous city because it is expensive, but a city where the resident class and way of life have fundamentally changed because of the price. In the future, we must pay more attention to where those pushed out of the market are forming new residential bases, rather than the price indicators themselves. This is because the change in Tokyo is not a decline, but a turning point in the massive reorganization of the entire metropolitan area's spatial structure.
