When the plate sank under the continental plate at the Nankai Trough off the Shikoku sea, some of this limestone mass was scraped off and some remained, which was later uplifted to an altitude of 1,400 m to form this structure by the virtue of orogenic movements in Shikoku's mountainous district about 2 million years ago.(Cited from Karst Learning Center.
