○Location and Number of Prout Village Constructions [2]

     We are avoiding 4 km around the continental plate, but if a magnitude 9 class huge earthquake occurs, it shakes greatly from 10 to 20 km from the epicenter. The important thing is that earthquakes can occur anywhere in Japan, so the only thing to do is to make the house itself safe even if a huge earthquake occurs. If the house does not collapse and things do not fall from above, most fatalities can be avoided. Therefore, it will involve devising ways of arranging furniture and lighting.

    Of Japan's total land area of 377,900 square kilometers, about 33.6% or 127,000 square kilometers is considered habitable. Within that, construction of 2942 Prout Villages is possible. In these, 41,517,504 residences can be built, but the number of households in Japan as of 2016 was 51,850,000, of which 16,800,000 were single-person households. The number of single-person households in Japan has been increasing year by year, but using the 2016 figures, if you build 1100 residences for single-person households where 6 people live in each Prout Village, housing can be provided to all citizens.

◯In the case of one Prout Village
There would be 13,012 family residences, and 1,100 single-person residences x 6 rooms = 6,600 rooms, totaling 19,612 units (14,112 of which would be houses).

◯For the 2,942 Prout Villages throughout Japan
There would be 38,281,304 family residences, and 3,236,200 single-person residences x 6 rooms = 19,417,200 rooms (units), totaling 57,698,504 units (41,517,504 of which would be houses).

◯As a comparison, the number of households in Japan (as of 2016)
There were 35,050,000 family residences and 16,800,000 single-person residences, totaling 51,850,000 residences.
