Our guide

Ryūsendō, in the town of Iwaizumi, Iwate, is one of Japan's three largest limestone caves. Our source says little more than that, so this page is short.

We have not checked opening hours, fees or a public-transport route, so plan the journey on the map and look for local information before you go.
