The Abe River is a first-class river that is the birthplace of mochi. The fragile geological embankments are collapsing in many places, and the river is being filled with sediment. Upstream is the secret hot spring Umegashima Onsen.
It is one of the most beautiful first-class rivers in Japan and never runs dry. Serpentinite (also known as mugwort stone here) can also be found in abundance. Shizuoka City's pride river.
It was a scree, or rather a river of sand and gravel. Sometimes the mountain on the other side of the road collapses from the top, which is scary. It's basically a gentle uphill climb, so it's a good place to bike to the headwaters. There's also a hot spring.
