Do you know that there is a “temple” underground in Tokyo? To be precise, the official name of this “Temple” is Metropolitan Area Outer Underground Discharge Channel. It is located in Saitama Prefecture, adjacent to the north side of Tokyo. During heavy rains, this underground space acts as a dam to collect rainwater. Water is collected in this space from small rivers and efficiently discharged to large rivers. That keeps Tokyo safe. This “temple” is open to the public every day except on heavy rain days (reservation required). Please refer to the official website below for details. There is an automatic translation button at the top right of the site. Oops, there is no elevator in this temple. Please be careful as you go up and down 110 steps!
