Nagatoro Iwadatami Rocks & River Boats
Drift past stone terraces shaped by the Arakawa River.
The river has carved crystalline schist into a rock terrace roughly 80 metres wide and 500 metres long, a nationally designated scenic and natural monument. Traditional boat rides pass rapids and the red cliffs of Chichibu. Cherry blossoms, autumn leaves and nearby Hodosan’s winter flowers offer reasons to return.
