The Land Ministry opens this underground cistern in Kasukabe, Saitama prefecture, a suburb of Tokyo, Japan, to the public once a year where several thousand people visit the so-called “the underground temple”. The 14,000-square-meters and 18-meters-high structure is used to hold water from rivers around the facilities temporarily to avoid floods in case of heavy rain.
