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.
View of the levee downstream from the left bank
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.
View of the conduit
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.
View of flood discharge
This is a wide flood discharge with a curved frontage. It must be a spectacular sight to see the water gathering and flowing here.
View of the flood discharge from another angle
It is shaped like part of a mortar and has a surprisingly sloping angle.
View downstream (downtown Tarui Town)
The Noo Plain can be seen in the distance, as well as the conduit, the end of which is not visible.
View of the monument
A magnificent stone monument has been erected.
View of the top edge from the left bank
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.
View of the embankment on the lake side from the left bank
It is on the dam lake side, but it looks like a rock-fill dam because it is paved with stones.
View of the dam lake
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...
View of water intake
Water intake facilities are located on the left bank.
View downstream from the top
There are houses immediately downstream, but the scenery is long and quiet.
View of the discharge from the water intake
Water taken from the intake on the left bank probably flows out here.
View of the embankment on the lake side from the right bank
Because the water level was quite low, it still looks like a rock-fill dam when viewed from the dam lake side.
View of the conduit from the right bank
Looking at the conduit from this position, it looks like a huge slide has been installed.
View of the levee downstream from the right bank
It is a dam with strong appeal. Well, it is the dam lake that is appealing...
The levee is still well maintained.
View of the levee from downstream
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.
View of the conduit from downstream
Oh. This one is also slanted. Large scaleconduitThe following is a list of the most common problems with the
It is rare to find an earth on this scale, so I recommend it.

Other facilities/observations
Rather than a parking lot, the dam site is quite large. The downstream side is a bit narrower, so please visit with good manners.
