Dam in Chubu Region

989-Taiwu Dam/Yasooka Dam

Taifu Dam is a gravity-type concrete dam built in 1935 by Yahagi Hydro Corporation, the successor to Momosuke Fukuzawa's will. The dam is now owned by Chubu Electric Power Co. The dam's curvaceous embankment is so beautiful that it has been selected as one of Japan's Modern Civil Engineering Heritages. The dam was used to supply 50-Hz electricity to eastern Japan in the aftermath of the Great East Japan Earthquake. / Gravity concrete dam / 50m

1057-Oi Dam

The Oi Dam is a gravity concrete dam dedicated to power generation, built by Momosuke Fukuzawa, the son-in-law of Yukichi Fukuzawa and founder of Daido Power Company. The dam was built in the Taisho Era (1912-1926), giving it a sense of Taisho Romanticism. The dam lake formed by the Oi Dam on the Kiso River has since become a tourist attraction in the Tokai region as "Ena Gorge. / Gravity concrete dam / 53.4m

1209-Oiike

Oiike is an irrigation-only earth dam located in Koda-cho, Nukata-gun, and has been recently renovated. It has just been renovated and is beautiful, and it is also an assertive dam, as you can see on the embankment. I hope the local farmers will continue to do their utmost to make the dam work as well as possible. Many cherry trees have been planted along the lakeside, making it a popular cherry blossom viewing spot. / Earth dam / 31m

1201-Chikaga Iriike

Rikigairi Pond is an agricultural reservoir located near Kotosawa Regulating Pond, and was built by the local people. It is not easy to approach the embankment, perhaps because it is cherished by the local people. The flood discharge was also photographed through the fence. I was forced to take this picture, so I ignored the level. / Earth dam / 19m

The Kotosawa Regulating Pond is located in Koda-cho, Nukata-gun, south of Okazaki City, Aichi Prefecture, and is a central impervious zone-type rockfill dam under the jurisdiction of the Ministry of Agriculture, Forestry and Fisheries for irrigation purposes only.

3084-Takigawa Dam

We arrived at the Takigawa Dam. Approaching from an empty main street, the embankment can be glimpsed at the end of a curve. The Taki River Dam is a gravity-type concrete dam built in the Takayama area of Iga City on the Taki River, a small branch of the Hijiki River, a branch of the Kizu River, a branch of the Yodo River system. It is a very simple, cost-effective dam of the type often seen in prefectural dams. / Gravity concrete dam / 29.8m

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)

The Ota River Dam is a gravity-fed concrete dam operated by Shizuoka Prefecture and was completed in 2008. I expected to see the pure white embankment, but it was a little too dark. I would like to revisit the dam again someday and report on it. / Gravity Concrete Dam / 70m

1228-Kisogawa weir (Magai headworks)

Although the Kiso River weir is more conspicuous for its role as a bridge (it is often referred to as the Umakai Bridge), I have a renewed awareness that it plays a major role in providing a stable supply of water not only to western Aichi Prefecture, where I live, but also to Mie Prefecture. / weir / 4.2m

1322-Yamamura Dam

The Yamamura Dam is an earth dam for industrial water use that also serves the purpose of preventing land subsidence due to pumping of groundwater. However, perhaps its greatest feature is that the Ise Bay Expressway runs right in front of it downstream. Without the expressway, it might have ended up as a mere earth dam. / Earth dam / 37m

The Isaka Dam is located in Yokkaichi City, one of Japan's leading industrial cities, and is an earth dam built by Mie Prefecture for the very purpose of developing its industry.

Otani Pond, located near Sekigahara in the Tenka area, is an earth dam owned by Gifu Prefecture and dedicated to irrigation.

History buffs, too, are welcome here! / Earth Dam / 18.7m
