There are two ravines in Ichinoseki Iwate prefecture: Geibikei and Genbikei.
They are magnificent.
You can take a river ride at Geibikei.
There are 18 different river rides in Japan, and this one is distinctive in that they use only a pole to navigate the river.
On the way back, the boatman sings an old song.
It was nice with a lot of minus ions and good views.
I enjoyed it.
