2317-Anauchi River Dam

Date of interview: 10/11/2019 (Friday) I originally came here to participate in the tour of the Anauchi River Dam, but I visited here to see the dam in advance, as a wild dam lover's intuition that I would not be able to act freely during the tour, or perhaps as a preview, or a location scouting exercise.... I visited the dam to see it beforehand...

2311-Omori River Dam

Date of interview: 10/12/2019 (Sat) I came to Shikoku to participate in a tour of the Anauchi River Dam, and since I don't often come to Shikoku, I carefully planned my visit to the dam and came to the Omorigawa Dam.

1168-Hatanagi Daiichi Dam

The twilight-colored embankment makes one imagine the world of Hades. When we reached the Hatanagi No. 1 Dam, the surroundings were completely tinted in twilight, and we were finally at the end of our tour of dams on the Oigawa River system. The dam tour of the Oigawa River system finally comes to an end. The dusk-colored embankment makes me imagine the world of Hades. I wonder if I'll ever go to the other side of the world to see a dam. / Hollow gravity concrete dam / 125m

1167-Hatanagi No.2 Dam

Tennozan Dam on the Oigawa River. It is endlessly far away. And the road is endlessly bad. Therefore, driving fatigue reaches its peak when you reach here, so if you feel even a little tired, be sure to take a break! Since the road is not connected, you will have to make a U-turn at the Hatanagi No. 1 Dam ahead. You will have to return to the rough road you just came from, so you need to be prepared for that when you get here. You are on your own no matter what happens... / Hollow gravity concrete dam / 69m
