吉野川第十堰, Water management structure on Yoshino River, Tokushima Prefecture, Japan.
The Yoshinogawa No.10 Sluice spans across the Yoshino River, featuring multiple gates and channels that regulate water flow. The structure maintains consistent water levels throughout the year for agricultural irrigation.
The sluice was completed in the late 1970s as part of Japan's agricultural infrastructure development. Its construction brought more reliable water control to the farming communities of Tokushima.
The structure links local farmers to the river's water resources, supporting rice growing across the surrounding countryside. Visitors can observe how this water source shapes the agricultural rhythm of the region.
The site is accessible to visitors, though you may encounter uneven paths and areas that become muddy during irrigation season. Wear sturdy shoes and watch for wet areas around the gates and channels.
The structure includes specially designed fish passages that allow migrating river fish to continue their natural journeys. This blend of engineering and wildlife protection is often overlooked by visitors exploring the site.
