View of the levee downstream from the Okinawa Expressway (Part 1)
Even though I knew that no one would be satisfied if I uploaded this kind of thing, I wanted to upload it as a proof that I had seen it....
Now, as the name suggests, the Hanna Waki Dam is a dam on the side of the Hanna Dam. I was really aiming for the main body of the Hanna Dam, but when I came across it, I saw the Waki Dam....

As the name suggests, this dam plays a minor role, but it is a magnificent dam with an embankment height of 37 m, a crest length of 500 m, and a rock-fill dam type.

The top of the embankment is exactly 500m long, so it can be used as a guide for the distance between cars when driving on the Okinawa Expressway... (I hope it will be).

The polarizing film on the bus made it look blue, and the shaking of the bus made it look askew, and the fact that we were in opposite lanes made the photo look confusing.
