Tohoku Japan

After the Tohoku region of Japan was hit by the Tsunami in 2014, the government began building 10m high walls alongside of the oceans, which significantly ruined the beautiful sceneries of Japan.

The proposal here applies the concept from vehicular air bags, which is only deployed upon impact for protection. The containers of 10 meter diameter airbags are planted alongside of the bay, and are deployed in the occurrence of tsunamis.
