The exhibition is consisted of 18 sections, they introduce us various things depend on the altitude. Underground facilities, resources, the remarkable things that modern science has found　about living things in underground,etc. Very fun and easy way of exhibit, so it makes us want to know about it more and more.

For example, a huge underground passage called “communal ditch” in “Deep Subterranean” – facilities spreaded out under Tokyo city. Under the ground where we can’t see, water, electricity, and network are all over in the space to support our modern life. Not only high rise buildings which we have been building so many amounts, but underground is getting possible to live for human.

Besides, it is said that the underground is comparatively stable environment in the earth. Various experiments using such a characteristic are being done.The project that preserves a food seed all over the world under the soil covered with the permafrost layer is done in Sbalbal island in Norway.

There is no need to say the size of the scale of the project, and the the name the “Noah’s Catafne project” is SF world already, but it is real project. Preservation using the underground is being done in Japan as well, and the time capsule is made when we had the Osaka Expo in 1970 and it is preserved under the soil.I hear that it will be opened in 5000 years later. It is a project that feels the time of the eternity.

About the beggining of life, there is a theory that it happend in the ocean, but apart from that they introduce us a theory that the clay mineral that forms the underground connect the molecule which is the base of life.
