A new trend is rising in Tokyo's 23 districts, as even used luxury apartments, also known as "oku-shon," are making up 20% of the real estate market. Despite the high price tags, these properties are attracting investors and private buyers alike, even amidst a fluctuating economic environment. As the most populated city in the world, Tokyo's real estate market continues to see a thriving demand for high-end residential properties.

Real estate in Japan, particularly in metropolitan Tokyo, has always been a subject of high interest due to the limited land and high population density. In Japan, owning a luxury apartment or 'oku-shon' in central Tokyo districts is seen as a status symbol, despite the high costs. It indicates not just wealth, but also a certain lifestyle and social standing.

Unlike in the U.S or EU, where people often prefer to buy new homes, in Japan there's a substantial market for second-hand properties, including luxury ones. This is in part due to Japan's unique combination of scarcity of land and high demand.
