Lurking deep beneath the outskirts of Tokyo is the Metropolitan Area Outer Underground Discharge Channel, engineered to shield the capital region from catastrophic monsoon and typhoon flooding. This colossal subterranean drainage system centers around an awe-inspiring surge tank supported by 59 towering pillars, creating the atmosphere of a cavernous concrete cathedral. Visitors on guided tours can walk across the floor of the echoing chamber and marvel at the jaw-dropping scale of Japan's civil engineering prowess. Its surreal, sci-fi aesthetic has also made it a legendary filming location for international movies, TV series, and music videos.
