Sacred Island of Okinoshima and Associated Sites in the Munakata Region

, officially Sacred Island of Okinoshima and Associated Sites in the Munakata Region, is a group of sites in northwest Kyūshū, Japan, that was inscribed on the UNESCO World Heritage List in 2017, under criteria ii and iii.
Background.
The three Munakata kami are said in the "Kojiki" and "Nihon Shoki" to be daughters of Amaterasu, spawned upon the sun-goddess' consumption of giant swords. Okitsu-Miya on the island of Okinoshima is part of the Shinto shrine complex of Munakata Taisha; no formal shrine buildings were constructed on the island; instead rock piles or yorishiro provided the focus for veneration. Over 80,000 artefacts were ritually deposited at the site from the fourth to the tenth centuries. These have been designated a National Treasure. They include mirrors and bronze dragon-head finials from Wei China; gold rings and horse-trappings similar to those found in Silla tombs in Korea; and fragments of a glass bowl from Sassanian Persia. The , powerful local rulers, controlled the route to the continent and "presided over the rituals". The many kofun or tumuli in the area are believed to be their burial ground.
