Local Tips
One of Japan's top three limestone caves — 4km of passages with extraordinary stalactite formations. The standard 1km tourist route is excellent; the adventure course into the unlit back passages requires advance booking and is genuinely challenging. The cave maintains 17°C year-round. Combine with Niyodo River and Hirome Market for a full Kochi day.
