Extending over 1,270 metres, Nippara Cave is one of the most famous limestone caves in Japan. The 800 metre-long public accessible path takes approximately 40 minutes to explore. Formed by the erosion of Paleozoic coal, the shiny limestone interior has made the cave’s main chamber impressive. The LED lighting in the cave also adds to its grandeur. Maintained at the constant temperature 11℃, the inside of the cave is cool and refreshing. It is the best place to visit during the hot and humid summer.
