Shimpokan Museum

Built in 1980 on the grounds of Hetsu-miya Shrine, the Shimpokan Museum displays artifacts excavated from Okinoshima, a sacred island used for ritual offerings from the fourth to ninth centuries. Researchers uncovered more than 80,000 objects between 1954 and 1971, all designated National Treasures, representing trade connections that stretched from ancient Korea and China to Sasanian Persia. Highlights include a pure-gold ring made in Korea around 520, a Chinese bronze mirror from around 320, and glass from the Persian empire. The third floor houses a separate collection of documents, samurai armor, and objects related to Munakata Taisha, including items from the 1905 Russo-Japanese War.
