Mt. Moriyoshi Dam

Free tours are at Mt. Moriyoshi Dam, the longest rock-fill dam in Northern Japan.

The view of Moriyoshi Shikimi Lake is superb.
The construction of the dam was done with care not to damage the nature as much as possible, so you can still enjoy the rich nature of Mt. Moriyoshi even now.

You can visit the top of the dam at any time.
Tours of the dam are free.
The management branch will carefully tell you about the dam.
The electricity is powered by hydropower!
