Kyusendo the Biggest Cave in Kyushu

Kyusendo

Kyusendo claims to be the biggest cave in Kyushu, being more than 4 kilometers in length. Only about 800 meters of it is open to the public.

It wasn't discovered until 1973. There is a small shrine and a Buddhist altar within the cave. It is also home to thousands of bats, though I didn't see any.

Though nowhere near as impressive as Akiyoshido, the biggest cavern in East Asia, it is more impressive than a few caves I have visited in Japan. Some people like caves, some don't.

It is located on the Kumagawa River in Kumamoto, about halfway between Yatsushiro and Hitoyoshi.
