1280-Sodani Dam

The Sodani Dam is an earth dam dedicated to irrigation water in Tsu City, Mie Prefecture. However, one cannot help but be reminded of the "Kintetsu Osaka Line train collision" (commonly known as the Aoyama Tunnel accident) that once occurred in the vicinity of this dam. Today, a nature park called "Higashi Aoyama Shikinosato" is spreading, as if to cover up the tragedy of the past. The visit to the dam is a bit sobering. / Earth dam / 19m

Yamaguchi Dam (Yamaguchi River Regulating Pond) is located in Seto City, Aichi Prefecture, and has lost its function as a flood control and water utilization dam.

The rusty parapet. The white water flowing in contrast with the frozen time is also beautiful. / Gravity concrete dam / 17.1m

Oiike is an irrigation-only earth dam located in Koda-cho, Nukata-gun, and has been recently renovated.

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
