Ōtanabe Seawall

The Ōtanabe Seawall extends along the coastline of Fudai, featuring concrete barriers and mechanical floodgates designed to counter incoming waves and storm surges.

Construction of the seawall commenced in 1967, following multiple tsunamis that struck the region, with completion of its main floodgate system in 1984.

The seawall represents Japanese engineering methods and coastal management strategies, reflecting local approaches to living harmoniously with natural forces.

During the 2011 earthquake, remote-operated mechanisms allowed quick closure of the floodgates, preventing major damage to the village of 3,000 residents.

The structure's effectiveness was demonstrated when it protected Fudai while neighboring towns experienced severe destruction during the 2011 tsunami.
