Aoshima Shrine and Cactus Park — Miyazaki's Classic Tropical Power Spots

Aoshima, floating south of Miyazaki City, is a small island about 1.5 kilometers in circumference, ringed by strange rocks known as the devils washboard (oni no sentakuita). The whole island is covered in subtropical plants, and Aoshima Shrine, enshrined at its center, is one of Miyazaki foremost power spots, famous as a deity of marriage ties. Along with its tropical scenery, many worshippers and sightseers visit.

Highlights

Aoshima Shrine enshrines three deities: Yamasachi-hiko (Amatsuhiko-hikohohodemi-no-Mikoto), known from the myth of Umisachi-hiko and Yamasachi-hiko, his consort Toyotama-hime-no-Mikoto, and Shiotsutsu-no-Okami. It is said to be the land to which Yamasachi-hiko returned from the palace of the sea god, and because it enshrines a married pair of deities, it has long gathered faith as a god of marriage ties, safe childbirth, and safe voyages. The whole island was regarded as a sacred place, so much so that ordinary people were once restricted from entering.

In the precinct there are plenty of pleasures of worship, such as the throwing of the ame-no-hiraka, where you cast an unglazed earthenware cup into the inner rock enclosure to make a wish, and the votive tablets tied by those praying for success in love. Deep in the island is the Motomiya, said to be the former shrine site, a quiet space surrounded by a grove of betel palms where you can feel the air of the islands original sacred grounds.

The Devils Washboard and the Betel Palm Grove

The devils washboard surrounding Aoshima is a formation of regular ridge-like rocks created by wave erosion, and at low tide its strange shapes appear clearly. Designated a national natural monument as the raised sea floor and eccentric wave-cut marks of Aoshima, it is a geologically valuable formation.

On the island, subtropical and tropical plants including betel palms grow densely, and the aged trees form thick greenery. Protected as the national special natural monument the Aoshima subtropical plant colony, it presents scenery unique to the tropics.

Enjoying the Seasons

Thanks to the mild climate you can enjoy it year-round, but spring through autumn, when the tropical atmosphere shines, is especially recommended. The washboard rocks are seen best at low tide, so checking a tide table before your visit lets you fully enjoy the drama of the formation. Summer offers a beautiful contrast with the blue sea, and even winter is relatively mild and easy for worship.
