Take a look below the streets of Tokyo city in the impressive flood tunnels.
50 meters below Tokyo lie colossal underground flood tunnels; an astonishing feat of engineering. At more than 4 miles long, the G-Can tunnel network included super-powerful pumps and huge tanks dedicated to keeping Tokyo dry during the rainy season and in case of flooding.
Construction of the tunnels began in 1992 and the complex is still growing. The main tank, often compared to an underground temple, has been used as an atmospheric backdrop in many movies and television shows. This giant tank measures 25.4m x 177m x 78m, is supported by 59 gigantic pillars and has seventy-eight 14,000 horsepower pumps to force the water back into the Edogawa River.
