○Location and Number of Prout Village Constructions [3]

Japan is experiencing a decline in birthrate, and it is predicted that the population will decrease to 125.96 million in 2020, 116.62 million in 2030, and 91.93 million in 2055. This means that the number of residences will decrease year by year. Unoccupied residences will be used as accommodation for people coming from outside.

This approach, put another way, is about not creating cities anywhere, and it's an idea that can apply to countries other than Japan. By setting a limit on the number of residences in a municipality, urbanization can be prevented. If urbanization occurs, it leads to a concentration in cities like Tokyo or Osaka, and if a large disaster such as a major earthquake occurs, village dwellers lose both food and transportation.

Next, the number of municipalities and residences from the "Possible locations for Prout Village construction" map.
