The low-lying eastern area of Tokyo is highly vulnerable to storm surges and flooding. As part of levee improvement efforts and seismic reinforcement measures following recent major earthquakes, a seismic retrofit project was carried out on the Sumida River tidal barrier.

Due to the narrow construction site located near residential buildings, equipment was transported and construction was carried out using barges.
