0000-Yokosawagawa Daiichi Weir

The weir is less than 15m in length, and without detailed data such as specifications, it would normally be an indigestible property, but this is a weir that is tasteful enough just to look at. We hope you will enjoy the real thing. / U15 (weir)

Ouenwa Dam

The Ouenwa Dam is a fictional dam that was the setting for Yuichi Shimpo's suspense novel "Whiteout," which was also made into a movie. It is supposed to be under the jurisdiction of the Nagami Power Station of the North Japan Electric Power Co. The model in the novel is Okutadami Dam (0500-Okutadami Dam), but Kurobe Dam (0848-Kurobe Dam) was used for the film location.

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

Tochigi Prefecture Dam

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

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

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

0940-Ishitoshiro Dam

Ishitashira Dam is a dedicated power generation dam for the J-Power Development Project and is one of the few gravity arch dams in Japan. There is a bridge downstream, from where you can see the dam directly in front of you. The mossy appearance of the dam gives it a nice flavor. The atmosphere is very nice. The sun was shining after the rain that day, but it made me forget the heat. / Gravity arch dam / 32m

0943-Yambara Dam

The Yamahara Dam is a dedicated power generation dam owned by J-Power Development, and hydroelectric power is generated at the Yugami Power Station downstream. Most of the embankment is a natural overflow emergency flood discharge. If the water were discharged from here, you would be able to feel the beauty of the place. The curve at the tip of the flood discharge is nice! / Gravity Concrete Dam / 23m

1126-Kawaura Dam/Kaore Dam

In many ways, I'm sorry if I got your hopes up! The Kawaura Dam is located upstream of the Kami-Osu Dam. The dam lake formed by the Kawaura Surabu Dam and this dam together is the upper regulating reservoir (upper pond), and the dam lake formed by the Kami-Osu Dam is the lower regulating reservoir (lower pond), and pumped storage power is generated between them. The effective drop-off is said to be as high as 486 meters.

Season for Familiarization with Forests and Lakes 2009 - Maruyama Dam

The 2009 event was held at Yokoyama Dam and Maruyama Dam. At the Maruyama Dam, visitors could not only tour the inside of the embankment, but also go up to the "Gate Pier" at the top of the embankment from the elevator on the first floor, and enjoy a panoramic view from there. Unfortunately, the weather was unfavorable on the day of the event, but due to the rain that had fallen the day before, it was a miraculous event to be able to see the powerful discharge of water from the dam.

Season for Familiarization with Forests and Lakes 2009 - Yokoyama Dam

The "Season for Familiarization with Forests and Lakes" refers to the period (from July 21 to 31 every year) during which the Ministry of Land, Infrastructure, Transport and Tourism, the Forestry Agency, and the Japan Water Agency began to promote awareness of dams, dam lakes, and water sources. In 2009, however, dam enthusiasts from all over the country gathered for the event in particular. There is no reason not to go to this one. This article reports on a tour inside the dike of Yokoyama Dam.
