Hokuzan Dam

The Hokuzan Dam is a concrete structure spanning the Kase River in Saga Prefecture. The facility holds water in a large reservoir and supplies irrigation to farmland across the region.

The dam was built between 1950 and 1956, creating an important water management system for the prefecture. The project arose from the growing water needs of agriculture during that period.

The Saga Land Improvement District manages this concrete structure, which supports local agricultural practices through its irrigation system.

The dam is best viewed from the nearby parking area or from local viewpoints where you can see the full structure. The best time to visit is during fair weather, when the water surface is clearly visible.

The facility also generates electricity through water power, contributing to energy supply for local communities. This dual function makes it more than just an irrigation system.
