Okinoshima is an island off the coast of Munakata, Fukuoka, Japan. It is considered sacred land by the local Munakata Taisha. The island's population consists of a single employee of the shrine. He is one of about two dozen Shinto priests who spend 10-day intervals on the island, praying and guarding against intruders.
The entire island is considered a shinto kami, and the island is off limits to women. For centuries, only 200 men were allowed on the island on one day each year after they had "purified" themselves in the surrounding sea.
The island covers area of 97 ha and has maximum elevation of approximately 244 m.
