Japan is currently grappling with a staggering demographic crisis as the number of abandoned homes, known locally as akiya, reached a record high of 9 million units in 2023, according to data from the Ministry of Internal Affairs and Communications. This phenomenon, which spans from rural villages to the outskirts of major metropolitan centers, is being driven by a rapidly aging population, a declining birth rate, and a cultural aversion to the resale of older homes.
The Roots of the Housing Surplus
