It has been called Japan’s underground “Parthenon”, a cavernous complex charged with protecting Tokyo and surrounding areas from catastrophic flooding — a risk experts warn is growing as climate change advances. Above ground, there is little to give away the cathedral-like feat of engineering that forms the main reservoir of the Kasukabe flood tank, the largest facility of its kind in the world. The immense structure — deep enough in some parts to hold the Statue of Liberty — funnels away and redirects excess water from storms and typhoons, protecting one of the globe’s most populous capitals.
