In Japan, "akiya" refers to an empty house, often abandoned or left uninhabited due to various reasons such as population decline, urbanization, or inheritance issues. These empty houses have become a significant social and economic problem in Japan, particularly in rural areas where the population is aging and declining.

Akiya can be relatively affordable because they are often sold at a steep discount or given away for free by local governments, property owners, or real estate agents who want to get rid of them quickly. Additionally, the cost of renovation and upkeep for an old, empty house can be quite high, which further decreases their value. In some cases, akiya can be bought for as little as 1 yen, although frequently prices can be comparable to property prices in other countries.

Keep in mind that purchasing and renovating an akiya can be a complex process, as there may be legal and financial issues to address, such as unpaid property taxes or inheritance disputes. Additionally, many akiya are located in rural areas, which may not be convenient for those who prefer to live in cities. Despite these challenges, the Japanese government has been actively promoting akiya revitalization projects to encourage more people to invest in these empty houses and help address the country's housing shortage.
