It is located in Kasukabe, a satellite city of Tokyo. This facility is the "Metropolitan Area Outer Underground Discharge Channel" managed by the Ministry of Land, Infrastructure, Transport and Tourism, but well known as the "Underground Temple" due to its unique structure.
The function of this facility is to transport the flood water from the rivers to the underground tunnel so that it can be diverted and drained out to the safer large river. It means the facility for preventing Tokyo Metropolitan Area from floods.
If you have a free day during your stay in Tokyo, why don't you visit the amazing facility?
Outline of the facility tour is as follows:
Maximum number of participants: 50 people / tour

Participation fee: 1,000JPY / person
