This is Japan's largest underground flood control facility. Where I'm standing is not even half its height. It has another level underneath. In total, it is 70 ...meters below ground. To put that into perspective, you could fit the statue of liberty on top of a four story building and still have a little room left.

There are 5 of these 'banks' as they call them in the facility, and each uses gas turbine engines pumping out 1400 horsepower each and spinning at 4000rpm, capable of pumping 50 cubic meters of water a minute.

The last time this was used was last October 25, during the big storm. It marked the 7th time it was used this year. The year before was zero.
