Date of interview: 11/19/2014 (Wednesday)On this day, I visited Nasu Shiobara in Tochigi Prefecture for the first time in four years. The last time I visited Nasu Shiobara, I took the Shinkansen bullet train to participate in a tour of the Yashio Dam and the Snakeo River Dam, but I felt it was a waste of a long trip, so this time I drove to the me...

0583-Snake River Dam / Sabigawa Dam

The Snake River Dam is a dam that functions as a pumped storage reservoir for pumped storage power generation with the Yashio Dam. The public is not allowed to enter...rather, to get to this dam, you have to go through a tunnel to pass through the power station, so you cannot go straight to the dam in effect. / Gravity concrete dam / 104m

0582-Yashio Dam/Yashiodamu

The Yashio Dam is a rare asphalt-facing fill dam that uses asphalt as an impermeable wall, and functions as an upper reservoir for pumped-storage power generation with the Snake River Dam. It is a rare type of asphalt-facing fill dam that uses asphalt as its barrier wall. This article introduces the site and the Shiobara Power Plant, which is located underground. / Asphalt-facing fill dam / 90.5m

0571-kawaji dam

It is the fourth tallest arch dam in Japan, and the catwalk can be visited. It is indeed a dam full of attractions. Of course, it is not only a sight to see, but it also works wonderfully and is an important base for protecting the downstream Kinugawa River. Protecting the Kinu River means protecting the urban areas downstream. We must not forget that. / Arch dam / 140m

0563-kawamata dam

Kawamata Dam is the longest vertical arch dam in Japan, tucked away in the midst of nature. It is also characterized by its compactness and various structures in a narrow space. The details here and there on the embankment are eye-catching. Also, since it is a long walk from the parking lot, it is a physical challenge to visit. / Arch dam / 117m

0578-Kuriyama Dam/Kuriyama Dam

Kuriyama Dam is a rockfill dam that functions as an upper reservoir for pumped-storage power generation with Imaichi Dam (0579-Imaichi Dam/Imaichi Dam) as a lower reservoir. The dam is interesting on the way to the dam, as it is visible after passing through a pasture, its gate, and a tunnel. It is recommended for driving, hiking, mountain climbing, etc. / Rockfill dam / 97.5m

0556-Kurobe Dam/Kurobe Dam

Kurobe Dam is located not in Toyama Prefecture but in Tochigi Prefecture. Japan's first concrete dam for power generation, built in the Taisho Era (1912-1926), is a stone-lined dam with style, elegance, and history. You can feel a little bit of Taisho Romanticism on your skin. There is also a hot spring nearby. / Gravity concrete dam / 28.7m

0558-dorobe dam

The Torobe Dam is owned by the Tokyo Electric Power Company and is dedicated to power generation. It can only be seen from the other side of the dam lake, and the embankment cannot be approached. Rumor has it that there is a path that leads to the embankment, but you will probably have to paddle through the bushes. If you take the wrong path, you will end up on the cliff, so it is safer not to go that far. / Gravity Concrete Dam / 21.6m

0588-Mikawasawa Dam

Mikawasawa Dam is a dam deep in the mountains that can only be reached on foot. Although it appears to be off-limits, we were able to enter this dam without any problems. Animals such as bears may appear, so we recommend that you bring a bell or other countermeasures when you visit. The best point of this dam is the embankment seen from the dam lake side. / Gravity concrete dam / 48.5m

0559- Ikari Dam/Ikari Dam

Gojuri" is the name of a place named after the distance of 50 ri from Tokyo's Nihonbashi Bridge, and the Gojuri Dam is a high dam, completed in 1956, with an embankment height of 112 meters. The construction of this dam has a long history. The history oozes from the embankment. It is a stately dam composed of the best mix of such history and modern technology, such as gate repair and cooperation with neighboring dams. / Gravity concrete dam / 112m

0560-Koami Dam

The Koami Dam is a small but fully enjoyable dam, owned by Tochigi Prefecture and dedicated to power generation. It also serves as a reverse control dam for the Kawaji No. 1 Power Station and as an intake dam for the Kawaji No. 2 Power Station and the Koami Power Station, and despite being dedicated to power generation, the top of the dam is unusual in that you can walk around it. / Gravity concrete dam / 23.5m

0557-Naka Iwadamu

This is the next dam we visited after Imaichi Dam (0579-Imaichi Dam), but we could not find it right away, even though we had checked in advance that it was along the R121 (Kinu Bypass). It was not easy to find it, although I had previously checked that it was located along the R121 (Kinu Bypass). However, it is located far from the national highway and a short walk is required. / Gravity arch dam / 26.3m

Tochigi Prefecture Dam

0579-Imaichi Dam/Imaichi Dam

Imaichi Dam is owned by the Tokyo Electric Power Company (TEPCO) and serves as a lower reservoir for pure pumped-storage power generation between it and the Kuriyama Dam (0578-Kuriyama Dam), which serves as the upper reservoir. The embankment gives a slender impression, and has an air of a dam that one would not expect from a dam dedicated to power generation. The atmosphere is quiet. No one is around, and no one comes. The only sound is the sound of water. This atmosphere is not bad. / Gravity concrete dam / 75.5m
