The Honzawa Dam was built as part of the Sagami River Comprehensive Development Project for an artificial lake to generate power from the Shiroyama Dam and a pure pumped storage system.
Incidentally, the dam lake of the Honzawa Dam is "Shiroyama Lake" and the dam lake of the Shiroyama Dam is "Lake Tsukui.
In other words, the water in Shiroyama Lake (Honzawa Dam) was drawn from the lower elevation Lake Tsukui (Shiroyama Dam)... and it is confusing.

We did not have much time for this interview, so we did not even go to the top end of the building. If I had more time... If there was no traffic jam, we would have had plenty of time....

Surprisingly, there were many tourists. They seemed to be fishing, but if pumped storage power is being generated, the water level must change a lot, and I think fishing is also prohibited, but I am not sure if fishing is prohibited or not.
There is what appears to be a surface aeration facility on the left side of the photo, but this too has not been confirmed.

Other facilities/observations
| Parking lot | ○ | Since this is not a dam associated with a river, the basin area and river name are not available. Some dams are for water supply, while others are built only for pumped-storage power generation. Kanagawa's dams may have a small number of units, but they are deep. In addition, there may have been a restroom.... |
