En el popular Itinerario y experiencia de Shimanto

Not that the service provider isn’t good, it’s the boat trip itself. The view of the river isn’t as breathtaking as advertised. The drive from shimanto city is about 20 minutes. If you leave taking the opposite direction, hoping to explore nearby areas, it’s definitely not an easy drive: super narrow roads in the mountain, with cars coming from the opposite direction quite frequently, it’s scary, especially if you don’t have a k car and aren’t used to driving in Japan.

梅雨明け後、殆ど雨が降ってなく水流が少なかったですが、ガイドさんのお陰でどちらも楽しめました。水流が多い時に再チャレンジしたいです。
