Date of visit: 12/10/2014 (Wed.) We came to the Onwara Dam, the ninth dam we visited that day, by heading north along the Yoshii-gawa River from the Tomada Dam.

Date of interview: 12/10/2014 (Wed.) The fifth unit of the day was Ichinotani Pond. As the name suggests, it is a reservoir and an earth dam.

1877-Kawakami Dam / Okayama Prefecture

Kawakami Dam (Okayama Prefecture) is a somewhat confusing dam with the same name as the dam under construction in Mie Prefecture (as of September 2013) and the dam in Yamaguchi Prefecture. However, this one is a very ordinary agricultural reservoir. The flood discharge is of the free overflow type typical of earth dams. Earth dams are agricultural treasures. / Earth dam / 24m
