0699-Doshi Dam / Kanagawa Prefecture

The design of the parapet, the moss stuck to the embankment, the water that does not decay even after crossing the equator.... Located on the border between Kanagawa and Yamanashi Prefectures, the dam is easy to find because a prefectural road runs along the top of the dam. 3 roller gates are the main feature of the dam, and although it is small, the design of the parapet tells of the good old days. / Gravity concrete dam / 32.8m

0697-sagami dam

This dam is located on Lake Sagami, one of the most popular leisure spots in the Kanto area. The roads around the dam were crowded with people. However, the area around the embankment was extremely deserted and even had a desolate atmosphere. The only people around the embankment were us and some boys who were fishing. / Gravity Concrete Dam / 58.4m

3243-Miyagase sub-dam (Ishigoya dam)

Located on the Miyagase Dam site, it is a natural place to visit if you visit the Miyagase Dam. It is not just a sub-dam. It is a perfect dam that serves as a reverse regulating reservoir for a power plant, maintains the water level for the water supply, reduces the force of water discharge from the Miyagase Dam, and even generates electricity. It is not a sub-dam that should be kicked out of existence. It is a dam that works superbly. / Gravity concrete dam / 34.5m

0696-Numamoto Dam

This is a phantom dam that sinks when the water level of Lake Tsukui, dammed by the Shiroyama Dam, rises. It is almost invisible because it is covered with grass and trees, but I could see that it is actually submerged. The height of the embankment is supposed to be 25.5 meters, but it does not seem high at all. The top of the embankment is supposed to be 126m long, but you don't feel its length. / 25.5m / Gravity Concrete

0701-Honzawa Dam

The Honzawa Dam was built as part of the Sagami River Comprehensive Development Project for the Shiroyama Dam and an artificial lake for pure pumped-storage power generation. Incidentally, the dammed lake of the Honzawa Dam is "Shiroyama Lake" and that of the Shiroyama Dam is "Lake Tsukui. In other words, the water in Shiroyama Lake (Honzawa Dam) was pumped up from Lake Tsukui (Shiroyama Dam), which is at a lower elevation... and confusing. / Rockfill dam / 73.0m

0700-Shiroyama Dam

Because Shiroyama Dam is close to central Tokyo and to Sagami Lake, which most leisure-seekers in the Kanto region have visited, the surrounding roads are very busy with cars on their way to the dam. National Highway 413 runs above the top of the temple, which may be the only national highway in Japan with such a heavy traffic volume. / Gravity Concrete / 75m

0698-Sagamihara Sedimentation Pond

Sagamihara Sedimentation Site, a dam dedicated to waterworks sedimentation site. On the map, it is called the "Yokohama Waterworks Sedimentation Pond. As the name suggests, it is located on the Yokohama Waterworks that carries water from the Sagami River to Yokohama, and is a facility that performs sedimentation treatment of impurities in the water. Because the dam is located within the prefectural Sagamihara Park, it has been designated as one of the "50 best bird-watching spots in Kanagawa" and is an excellent spot for bird-watching. / Earth dam / 18.5m

The Miyagase lakeside parkland has not only a park, but also a shopping area, where visitors can have a meal. There is also a souvenir shop where visitors can purchase local specialties. / Gravity concrete dam / 156m
