Yodogawa Ōzeki

Yodogawa Ōzeki is a weir spanning across the Yodo River that manages water flow through movable gates and systems. The structure directs water distribution to different areas of Osaka based on daily and seasonal needs.

The structure was built in 1983 in response to water quality challenges in Osaka during rapid urban growth. Its construction was part of broader efforts to improve the city's infrastructure for a growing population.

The weir functions as a hub in Osaka's water system, affecting how the city manages its most essential resource. The structure shapes how people in the region think about water use and environmental balance.

Visitors can view the working water management system up close and watch how the structure operates daily. Group tours through the Yodo River Office offer insights into the facility's operations and regional water management.

The amount of water released changes significantly between high and low tide, with the structure releasing roughly double the volume at high tide. This tidal adjustment reveals how the system is designed to work with natural water cycles rather than against them.
