The Fuwa Hokubu Disaster Prevention Dam is an earth dam exclusively for flood control, constructed as a subsidized project by the Ministry of Agriculture, Forestry and Fisheries and under the jurisdiction of Gifu Prefecture. It is better known locally as Myojin Lake, and there is a large information sign on the main road that reads "Myojin Lake (Fuwa Disaster Prevention Dam). It is also more famous as a dam lake than as a dam (embankment), perhaps because fishing can also be enjoyed.

The name "Myojin Lake" is written in large letters on the embankment. As a dam enthusiast, I am a little disappointed, but perhaps this is because "Fuwa Hokubu Disaster Prevention Dam" gives a rather rugged image.

The height of the embankment is 42 m, which is high for an earth dam, and the size of the flood discharge is also large in comparison.

This is a wide flood discharge with a curved frontage. It must be a spectacular sight to see the water gathering and flowing here.

It is shaped like part of a mortar and has a surprisingly sloping angle.

The Noo Plain can be seen in the distance, as well as the conduit, the end of which is not visible.

A magnificent stone monument has been erected.

The top of the mountain is accessible to cars, but it is a dead end after passing through the top. The top edge is wide enough for two cars to pass each other.

It is on the dam lake side, but it looks like a rock-fill dam because it is paved with stones.

The road on the right bank of the dam lake is Gifu Prefectural Road No. 257 Kawai Tarui Line, but the road beyond it is not connected. However, Route 257 also runs from Ibigawa Town (formerly Kasuga Village), and both roads are cut off by the Iwate Pass. Perhaps they plan to connect them in the future, but I doubt it...

There are houses immediately downstream, but the scenery is long and quiet.

Water taken from the intake on the left bank probably flows out here.

Because the water level was quite low, it still looks like a rock-fill dam when viewed from the dam lake side.

Looking at the conduit from this position, it looks like a huge slide has been installed.

It is a dam with strong appeal. Well, it is the dam lake that is appealing...
The levee is still well maintained.

We then moved to the downstream side of the river. We could see the fish from downstream. However, I wanted to use a wider angle. Also, it is at an angle.
