赤崎鍾乳洞 (Akasaki Limestone Cave) is a rather small cave with some nice speleothems. There are areas with microgours. The visitors are equipped with a helmet and a torchlight, which is actually both unnecessary. We are never sure if the operators think they are necessary, if they offer them simply because its customary, or if it is intended to make the cave more interesting. The electric light is just a series of light bulbs along a cable in the middle of the ceiling but definitely sufficient. The cave is entered down a staircase where three passages meet. The right passage is acul de sac and you have to return. The other two passages are connected and form a loop. The trails are sometimes slippery with dripping water and clay, so we recommend good walking shoes.

Yoron is a small island located far south of the main islands of Japan. The next island to the south is Okinawa, the biggest of this group of islands.
