In Akiyoshidai National Monument, there is a geo-guided tour where you can learn about the formation of the earth while walking, a karstrogaining tour where you can run through the earth, a geo-guided tour in the natural monument Akiyoshido Cave, a nighttime cave expedition where you can walk in the darkness after the cave is closed and the Gyeongcheong-dong Cave Exploration Tour where you can explore the cave with a guide, and many more! There are many exciting MINE exploration programs. We look forward to building this program in Mine City, Yamaguchi Prefecture.
