Magai Head Works

Magai Head Works is a facility with multiple concrete structures spanning the Kiso River that regulate water flow for irrigation and farming. The structures distribute water across the region and manage its flow throughout the growing season.

The facility was completed in 1976 and marked a milestone in modernizing water management between Aichi and Gifu Prefectures. Its construction enabled more reliable control of water amounts for farming across the region.

The structure shows how Japanese engineering balances farming needs with nature protection through water management. You can see this balance working in everyday practice when you visit.

You can reach the site from local roads connected to Imao Bridge and Makai Bridge, which offer good viewing points. From these locations, you can observe the water regulation system and explore the surrounding area.

The facility includes a specialized ladder system for fish that allows aquatic animals to safely pass over the structure. This feature shows how modern water management considers the needs of wildlife.
