Shoryudo Caves

Discovered in 1963, the Shoryudo Caves are the largest caves on Okinoerabu Island and the second longest in Japan, extending over 3.5 kilometers through Amami Gunto National Park. The limestone formations include roughly 300,000 stalactites and Japan's largest known flowstone. The limestone here is relatively free of discoloration and catches light vividly. Cave heights range from 20 meters down to just over 1 meter, requiring visitors to crouch in sections. Stalactites grow about 0.3 millimeters per year, and water continues to flow through most of the caverns. The caves are open daily 9 a.m. to 5 p.m. Admission is 1,100 yen for adults.
