Projected Population by Municipality in 2050 (2020=100)

The National Institute of Population and Social Security Research (Japan) projects future population both nationally and by region based on the Population Census of the Ministry of Internal Affairs and Communications. According to the latest projections in Regional Population Projections for Japan: 2020—2050, the number of municipalities whose populations will decline in the coming 30 years is 1,651, which is more than 95% of all 1,728 municipalities (excluding 13 municipalities in the Hamadori region of Fukushima Prefecture, which are projected as a single region). The rate of population decline will tend to be higher in municipalities with smaller populations in non-metropolitan areas. The main factor behind this decline is natural decrease caused by low fertility. The pressure of population decline due to natural decrease is growing stronger over time. The Tokyo metropolitan area, which currently has a growing population due to net migration, will also begin to see its population decline.
