Fukushima Prefecture Dam

0505-Otori Dam

Located downstream from Okutadami Dam, this is a dedicated power generation dam owned by J-Power Development. It is off-limits to the general public. We arrived at the Otori Dam on the back of a microbus provided by Power Supply Development Co. Again, I had not studied the dam beforehand, so I did not know the details of the dam. Although we could not see the entire embankment due to the power plant building, the solid appearance of the embankment is unique to the gravity-type arch. The white object hanging down from the right bank of the embankment is a hydraulic pipe for power generation. / Gravity arch dam / 83m
Niigata Prefecture Dam

0500-Okutadami Dam

A huge dam located on the border between Niigata and Fukushima prefectures that served as the model for the movie "Whiteout" starring Yuji Oda. Okutadami Dam's total water storage capacity is the second largest in Japan, following Tokuyama Dam. It is also the fifth tallest gravity concrete dam in Japan in terms of both height and effective water storage capacity. It is a very dignified dam. And it is quite tall even when seen like this. / Gravity Concrete Dam / 157m
Dam in Gifu Prefecture

1056-Takahashidani Dam

This is a power generation dam owned by Chubu Electric Power Company that stands quietly. The dam looks very old. According to the dam handbook, it was completed in 1919. In Japanese calendar, it was completed in 1919. It is the year of the Treaty of Versailles. It is not suitable for a date, but it looks like it could be used for fishing. It is good for a fishing date. It is also OK if you like old prewar buildings. / Gravity concrete dam / 18.5m
Yamanashi Prefecture Dam

0965-Kakimoto Dam/Kakimoto Dam

Like the Amahata Dam (0969-Amahata Dam), the Kakimoto Dam is an unusual dam owned by Nippon Light Metal, a private company that manufactures aluminum and other materials. It has an aura of being somewhat difficult to enter, but visitors can tour it without worrying. If you take your time and look around, you can enjoy the various flavors of this dam. / Gravity concrete dam / 46.1m
Kyoto Prefecture Dam

1405-Takayama Dam

The Takayama Dam is a gravity-type arch dam, which is rare in that it is both a gravity-type and arch-type dam. The embankment is quite thick, giving it an impressive sense of solidity. The words "manly" and "solid and sturdy" seem to fit the dam. This time, I came to see not only the dam but also the ume (plum) grove in Tsukigase, which is located upstream of the dam. / Gravity arch dam / 67m
Dam in Gifu Prefecture

1063-Kasagi Dam / Gifu Prefecture

The rows and rows of neatly arranged gates are very impressive. It is an old dam built before World War II, but it would have been difficult for prewar engineers to create such an old-fashioned formative beauty. Incidentally, it has been selected as one of "Japan's Modern Civil Engineering Heritage: 2000 Important Civil Engineering Structures in Existence. / Gravity concrete dam / 40.8m
Niigata Prefecture Dam

0769-cassadam/kassadamu

We are pleased to participate in the "4th Dam Web Ring Kassa Dam Off-line Meeting" and this event was made possible by the cooperation of Denpatsu Kaihatsu (hereinafter referred to as Denpatsu). So, the Kassa Dam is accessed from the road at the back of the Mitsumata area parking lot of the Kagura Ski Resort. / Rockfill dam / 90m
Niigata Prefecture Dam

0773-Nii Dam

The lower dam, where pumped-storage power is generated between the upper dam, Kassa Dam, and the Nii Dam, is the Nii Dam. If you are coming from Gunma, drive north on the Mikuni Kaido road for a while after entering Niigata Prefecture, and you will see a sign on your right hand side. This is a great area for a drive, so please stop by. / Rockfill dam / 87m
Gunma Dam

0606-Aimata Dam

Despite the small size of the dam, the facilities are quite extensive. Of course, there are many things to see and do. National Route 17 runs along the side of the dam lake, which was also called Mikuni Kaido in the old days, and it is said that Kenshin Uesugi also passed through here. Nearby is Sarugakyo Onsen, which would be a good base for sightseeing and touring the dam. / Gravity Concrete Dam / 67m
Gunma Dam

0623-Naramata Dam

When that huge dike covers your field of vision, you are already in a world of amazement. How could such a man-made structure exist so deep in the mountains! Incidentally, the Tokuyama Dam was the largest embankment in Japan before it was completed. It is now the second largest, but it is so huge that it doesn't matter anymore. Compared to the Tokuyama Dam, where you cannot go directly under the embankment, the Naramata Dam is a more friendly dam. / Rockfill dam / 158m
Gunma Dam

0612-Yagisawa Dam

The Yagisawa Dam is an arch-type dam in the Okutone Dam Group, and it boasts of its gigantic size. It is the Yagisawa Dam. It is built in a secluded area of Okutone, and no one is allowed to enter beyond this point. / Arch / 131m
Gunma Dam

0602-Sudagai Dam

The Sudagai Dam is a power generation dam located at the junction of the Naramata Dam and the Yagisawa Dam. When the dam was completed in the Showa period (1926-1989), it was named Naramata Dam, but the upstream Naramata Dam changed only the letters in consideration of the existing Naramata Dam. But in the end, the Naramata Dam, which was the senior dam, changed its name to the Sudagai Dam because it sounded the same and was confusing. So it is a dam that loves its little brother. / Gravity Concrete / 72m
Gunma Dam

0605-Fujiwara Dam

Fujiwara Dam is the first high dam in the Okutone Dam complex. Although it has the use of power generation, it is not a stand-alone dam, but a pumped storage power generation dam with the upper dam, Tamahara Dam, and Fujiwara Dam is the lower dam. I saw this figure first from the downstream side, so I came straight to the downstream side. It is nice to be able to get a shot from the downstream side. / Gravity Concrete / 95m
Gunma Dam

0598-komori dam

The entire embankment is overflowing, and when the river is full of water, it creates a magnificent "sudare discharge" because of the natural overflow. It was lucky for us to see the discharge because there are days when the water volume is low and the dam does not discharge water. As you head upstream of the Tone River from this dam, high dams appear one after another, so it is recommended that you aim further upstream. / Gravity Concrete / 33m
Dam in Mie Prefecture

1331-hasudamu

Oh man. Four years have passed since I visited this dam and my memory is quite fuzzy. I wonder how much I can remember. The lotus dam is one of those hard-to-read dams that is hard to read as "Hachisudamu". It was completed in 1991, and although it is located deep in the mountains, it has a lot to offer. / Gravity concrete / 78m
Dam in Mie Prefecture

1306-Miyagawa Dam

The area is full of nature, and there is even a campground. In addition, there are 1,000 cherry trees planted around the dam lake, and a sightseeing boat on the dam lake...it has become a tourist attraction, but I could not feel the atmosphere in this weather. I would like to go back on a fine day. / Gravity Concrete / 88.5m
Kyoto Prefecture Dam

1403-Amagase Dam

I visited this dam after I went to "Lake Biwa Wan Wan Kingdom" because it was going to be closed. It is a very old-fashioned dam, just like Kyoto. Byodoin Temple is very close to the dam, so it would be a good idea to visit there as well. By the way, there is another dam called "Kisenyama Dam" nearby, but unfortunately you cannot enter. / Arch / 73m
Dam in Shiga Prefecture

1361-Eigenji Dam / Shiga Prefecture

Eigenji-cho, where Eigenji Dam is located, is home to Eigenji Temple, which gave the dam its name, and is also famous for its autumn foliage. On the day of our visit, it was still too early to call it autumn, and the leaves were just beginning to change color. Eigenji Dam is also located along the Happu Highway R421. / Gravity concrete-fill combined dam / 73.5m
Dam in Shiga Prefecture

1351-Inukami River Dam

From the Hikone IC, take National Route 306 south, pass through Taga-taisha Shrine, and drive along a long, narrow prefectural road until you see the Inukami Dam. The village downstream of the Inukami Dam has a very nice atmosphere. However, despite the atmosphere, there are about three men on a motor scooter blowing a cigarette on the embankment... / Gravity Concrete / 45m
Dam in Shiga Prefecture

0000-kyokutani dam/magatani dam

Located downstream of the Anegawa Dam, it can be found on the way to the downstream park of the Anegawa Dam. I originally did not know this dam existed, but it is as if I discovered it during my coverage of the Anegawa Dam. However, it is well fenced in and quite closed. / Gravity concrete / 9.9m
