The Mikurodo-kutsu and Shinmei-kutsu Caves are two caves located at Cape Muroto. The priest known both as Kobo Daishi and Kukai trained here in pursuit of enlightenment during his youth. The cave’s names have particular meanings, the Mikuro means "the gods’ kitchen". Shinmei means "god’s lantern". Of the two caves the one that Kukai lived in while he was training is Shinmei-kutsu. He used Mikurodo cave for meditating. The name Kukai is comprised of the Japanese characters for sky and sea, so Kukai took this name because the only thing he was able to see from inside this cave were the sea and the sky. The sound of the waves from inside Mikurodo-kutsu is so wonderful that it was selected as "a sound that should be left for posterity" in the selection of the 100 best soundscapes in Japan.
