Address: Okinoshima, Munakata, Fukuoka Prefecture, Japan (subject to strict access controls)

Okinoshima is a small sacred island in Fukuoka Prefecture that forms part of the Munakata religious complex and is venerated in Shinto practice. The island contains ritual places and a small shrine and has yielded large numbers of ancient offerings, which contributed to its inscription as a World Heritage site.

The island’s religious status means access is highly restricted; traditionally only certain priests and officials were permitted to land, and modern restrictions continue to limit public visitation. Archaeological finds from the island include metalwork and other votive objects that document long-standing ritual activity.

Geographically it lies off the northwestern coast of Kyushu in the Genkai Sea, forming a distinct, rocky islet visible from the mainland and nearby islands.

  • UNESCO inscription: The island and its associated sites were inscribed on the UNESCO World Heritage List in 2017 for their ancient ritual significance and the large assemblage of ritual objects found there.
  • Access restrictions: Landing is strictly controlled for religious and conservation reasons; public access is normally prohibited and visitors generally view the island from boats or the nearby mainland.

What to See#

  • Okitsu-miya (shrine): A small hilltop shrine connected with Munakata Taisha that contains ritual structures and viewpoints but is not open for general landing without prior permission.
