The Sacred Island of Okinoshima and the associated sites in the Munakata Region of Fukuoka Prefecture in Japan form a unique cultural and historical site. Inscribed on the UNESCO World Heritage List in 2017, this area is celebrated for its rich spiritual significance and archaeological treasures. The island itself, along with the Munakata Taisha shrine complex and numerous kofun or tumuli, offers a window into ancient rituals and beliefs, particularly the veneration of the three female deities known as the Munakata kami, believed to be daughters of the sun goddess Amaterasu. This sacred site continues to be a testament to the spiritual history and cultural heritage of Japan.
