關宿水閘門

The Sekiyado Water Gate is a concrete and steel installation spanning the Edo River to regulate water levels and flow. The structure uses fixed piers combined with movable gate panels that can be raised or lowered to manage water conditions.

The Sekiyado Water Gate was built in the 1880s to address recurring flood problems affecting the region. Its construction marked a turning point in Japan's approach to managing major waterways during the modernization period.

The water gate serves as a gathering point for local celebrations that highlight the connection between water management and community life.

You can reach this location via a walking path that offers multiple viewing platforms along the site. The elevated areas near the dam provide the clearest views of the gate's operation and the river.

The gate operates using an unusual rack-and-pinion lifting mechanism that can be manually or motor-driven. This dual-control design was innovative for its time and visitors can still observe the system in action.
