The tourist route runs parallel to an underground stream, and passes a complex of 500 terraced rimestone pools, large stalagmites, and large columns.

Akiyoshidō is more than 8 kilometers long and currently the longest cave of Japan. Japan is mostly of volcanic origin, and there are only limestone patches, so there are no rwally long caves, but the Akiyoshidai karst plateau is quite large and full of caves. The limestone is important for many things in the modern world, so there are numerous limestone quarries in the area.
