What is Yugendo Cave?

Yugendo Cave! is a limestone cave in Higashiyama town, Ichinoseki city, Iwate.

It was discovered in 1980. It is said to be Japan’s oldest limestone cave with a stratum of 350 million years ago.

Generally speaking, a wall of limestone cave is covered with flowstone, but a most of Yugendo cave isn’t covered with it, because a sediment accumulated there, so you can see a original strata of 350 million years ago.

Many fossils such as trilobites and crinoids have been found in this place, so Yugendo Cave is also called the fossil mecca in Japan. The fossil of crinoid on the bedrock was first found there in Japan.

The underground lake ‘Jyoukon-no-izumi’ is also the best part of Yugendo Cave.
