With the help of the Japanese government

The Japanese government released a Minecraft map of the world's largest underground flood control facility. Not only is it free to download, it also allows you to explore one of the little-known iconic locations in the Tokyo area from the comfort of your home.
The underground discharge channels outside the metropolitan area, called G-Cans, are disaster prevention facilities in real life. It is famous for its “pressure-regulating water tank”, a huge sponge-like space with 59 huge pillars. It is a truly epic, worth fighting location, it is the most iconic sight of G-Can and even has the nickname “Chika Shinden” in Japan. With the atmosphere, it is also used as a location for music videos, Japanese TV series (such as Kamen Riders) and movies.

During the dry season, you can visit G Kans in real life, but thanks to Japan's Land, Infrastructure, Transportation and Tourism (MLIT), you can now also explore this atmospheric amenity at Minecraft. The department has released Videos on their official YouTube This briefly summarizes the purpose of G-Can and shows the appearance of the Minecraft blocky world.
Minecraft’s free G-Cans map includes not only the facility—and also a ground area of rivers, houses and communities, giving players a sense of how G-Cans protects real-life people and places. You can also go into the control room and try to drain the flood into the shaft to see how it works for yourself.

MLIT's entertainment for G-Cans in Minecraft is designed to educate people about the facility and its ways to prevent disasters. Even in Minecraft, exploring it can make players understand the absolute immense of G-Can. In real life, the concrete tunnel of G-Cans travels over 6 kilometers under Saitama Prefecture (part of the Greater Tokyo area). During the rainy season in Japan (June) and typhoon season (usually around September), its five axes capture flood-prone rivers and then gradually release them to the larger Edogawa River and Tokyo Bay. After more than a decade of construction, the G-Cans was completed in 2006 and has since played a huge role in combating floods in the region.
MLIT's G-Can's Minecraft map can be downloaded for free from the official website of this site Edogawa River Officemanage facilities. Minecraft Bedrock Edition or Minecraft Edition Edition or version 1.21.0 is at least version.
