Yasugawa near Ritto City after Typhoon 18 on September 16, 2013. These clips were shot hand-held from a few hundred meters above Yasugawa Ohashi, where the river flows under Japan Route 8. We can see the bridge and two small mountains: Mikamiyama (straight across the river from the camera) and Bodaijisan. The wind was quite strong, so I reduced the audio volume -12dB.
The river level had been higher. At the the high-water mark hundreds of PET bottles were along the riverbank. The river had not risen so high for a long time, so this time it picked up a lot of trash that people had left during summer. Every year I see thousands of plastic bottles along the riverbank in Ritto and Moriyama.
