Ōgibashi Lock Gate

Ōgibashi Lock Gate is a water control facility in Sarue that manages water flow between the Sumida River and inland channels using heavy steel gates. The structure allows vessels to pass through while maintaining different water levels on each side.

The lock gate was built in 1976 to manage water in districts between the Arakawa and Sumida rivers. It emerged as a solution to urban challenges of river navigation and flood control in the expanding city.

The lock gate represents Japanese engineering excellence in urban water management, integrating maritime transportation with flood prevention systems.

The facility operates daily and allows vessels of various sizes to pass through its gates. You can watch from viewing areas to see how the gates work and boats navigate the water level changes.

The lock features two gates of different heights that handle water level differences of up to 3 meters. This asymmetrical design is uncommon and represents a specialized engineering solution for the area's complex water conditions.
