He is a hidden character in the Mikawa region.

View of the top edge from the right bank
It is a dam that is not listed on some maps or at some scales, and there are not many visitors because the access road is not well developed. I went from Habu Dam to Ameyama Dam, but it took me a long time to get there, stopping occasionally to check the map....
View of the levee (downstream side) from the right bank
There is nothing special to note about it, and it is really tucked away in the rice paddies........ There were a few anglers, but not as many as at Habu Dam. However, the water in the dam lake is very clean and I could see many fish from the embankment, so it must be a good spot for fishing.

Although it is a small dam, it is a multi-purpose dam and plays an important role in the community.

The weather is beautiful and the mountains are very green. The water in the dam lake is also very calm.
