Location and Number of Prout Villages to be Built

Japan is a country where earthquakes are common and there is also a risk of tsunami. If we look back at the history of tsunamis in Japan in a time frame of 200 years, some areas have been hit by large tsunamis and people have died as a result. The Great East Japan Earthquake of 2011 sent tsunami waves 10 km inland. In Japan, if you go 10 km inland from the coast, you will often see mountains. Therefore, it is clear that Japan is a country that should build its settlements in mountainous areas. Past data also shows that huge earthquakes are more likely to occur at the borders of continental plates. However, it is still difficult to predict where they will occur.

Next, let's take a look at the possible locations and number of Prout Villages in Japan. First of all, please read the following QR code (Google Map) with your cell phone to see the map data.

This map is color-coded as follows.

Green line: continental plate

Blue circle 50km from the nuclear power plant in Fukushima Prefecture

One red circle is 4km in diameter.

(10km inland from the coast and 4km around the plate are avoided.)

Although 4km around the continental plate is avoided, if a huge earthquake of magnitude 9 class occurs, 10-20km from the epicenter will be shaken significantly. The important thing is that if you live in Japan, earthquakes can happen anywhere, so the only thing you can do is to make sure that your residence itself is safe even if a huge earthquake occurs. If the house doesn't collapse and things don't fall from above, deaths can be avoided for the most part. In order to do this, we have to be creative in the way we arrange furniture and lighting.

Of Japan's 377,900㎢, 33.6% or 127,000㎢ is considered to be habitable area. Within that area, 2,942 plutovillages can be built. As of 2016, the number of households in Japan was 51.85 million, of which 16.8 million lived alone. The number of one-person households in Japan has been increasing every year since then, but using the 2016 figures, if we also build 1,100 one-person dwellings in each Prout Village, a total of six people could live in each Prout Village, which would provide housing for the entire population.

One Prout Village.

1,012 family dwellings, 1,100 single occupancy dwellings x 6 rooms = 6,600 rooms, for a total of 19,612 dwellings (1,112 dome houses).

Total 2942 Prout Villages in Japan

3,828,304 family dwellings, 3,236,200 dwellings for single occupancy x 6 rooms = 1,941,200 rooms (units), total 5,768,504 units (4,151,504 dome houses).

Number of households in Japan (2016)

35.05 million family dwellings, 16.8 million one-person dwellings, total 51.85 million.

Japan's birthrate is declining, and the population is expected to decrease to 125.96 million in 2020, 116.62 million in 2030, and 91.93 million in 2055. This means that the number of dwellings will decrease every year. The unused dwellings will become accommodations for people from outside.

In other words, this approach means that there will be no cities anywhere, a concept that applies to countries other than Japan. By setting an upper limit on the number of dwellings in a municipality, we prevent it from becoming an urbanized area. If the city becomes urbanized, it will become concentrated in one area like Tokyo or Osaka, and if one major disaster occurs, the city residents will lose their food and transportation.

The following is the number of municipalities and dwellings from the map of Prout Village buildable locations.
