Ōtanabe Seawall

Ōtanabe is a coastal protection structure in Fudai that extends along the shoreline with concrete walls and mechanical floodgates. These components work together to shield the village behind it from waves and storm surge.

Construction started in 1967 following multiple tsunami events that had struck the region, with the main floodgate system completed in 1984. This timeline shows how the community gradually adapted its defenses in response to repeated coastal hazards.

The seawall shows how residents of Fudai have learned to coexist with the sea's power over many years. Visitors can observe how the village has built its daily rhythm around this protection structure, which is now part of the local landscape.

You can view the structure well from elevated points or along the waterfront path, which helps you understand the scale of the project. It is helpful to visit during different tidal conditions to see how the walls and gates function together.

The structure proved its worth in 2011 when it protected Fudai while neighboring villages suffered severe destruction. This performance revealed how critical this investment was for the community's survival.
