Tokyo’s Massive Underground Flood Protection

 | Grace Higgins

When you think Japanese you do think organized and ready for anything, and well that rings true for Tokyo’s massive underground flood protection system. In fact, Tokyo is preparing for flooding levels that the world has never seen before. North of Tokyo you will find Kasukabe, a system of underground sewers and pumps dedicated to protecting Tokyo from flooding.

A huge cavern of underground tunnels that are able to divert huge amounts of water from the regions most vulnerable areas of the country & especially the Tokyo metropolis. Kasukabe is a $2 billion anti-flood system, the most modern system of its kind in the world which was completed in 2006. It is a beautiful example of what global super cities can do to protect themselves from natural disasters.

In the United States and around the world, countries, and cities after being destroyed by countless hurricanes and storms are only now just coming to terms with the fact that urban development has to be constructed with adequate natural climate change protection. Buildings should be able to withstand earthquakes, hurricanes and tsunamis alternatively cities will continue to be demolished.

This is something that Japan has already practiced for decades. They prepare for natural disasters at levels that they have never even seen and therefore ensure that they are always prepared. It comes from a deep culture level that adapting to their weather has always been a part of their life, for example, in the Japanese language, there are over 70 different words for rain.

Even so, some intense storms have caused worries that Tokyo’s billion-dollar protection system is not strong enough for intense hurricanes. Questions are being raised if the country is ready to protect their stadiums and athletic grounds from weather problems during the 2020 Olympics. Rising ocean levels are also a major concern and another aspect of climate change that the government is readily preparing, building huge sea walls around the most vulnerable sections of their island.
