Taikoiwa is the highlight of one of Shiratani Unsuikyo Ravine’s three hiking trails. Sitting at a height of 1050 m, the rock offers spectacular views of the island’s mountain range. From here visitors can see most of the island’s high peaks including Mt. Tachu, Mt. Miyanoura, and Mt. Nagata. The name Taikoiwa, meaning “drum rock,” not only refers to the large size of the traditional Japanese drum, but also its sound. The rock emits a drum sound when hit, shifting in tone depending on which part of it is struck.
