Otaki Outdoor Adventures

Be fascinated by the fantastic world of Japan's largest natural iceberg cave.

Hyojun is formed when drops from a cave gradually drip and freeze to the ground. Located in Otaki Ward, Date City, Japan's largest ice stalagmite cave can only be entered on the "Otaki Hyojun Exploratory Tour" by the only authorized guide company. It grows like a bamboo shoot and is loved and cherished by the locals as a "treasure of the village". This is a rare experience where you can immerse yourself in the mysterious charm of the ice stalagmite while listening to stories about the history of the cave that only the guide knows. Why don't you visit the beautiful ice cave in a different space?
