Three sacred shrines for three daughters of the goddess of the sun and universe, Amaterasu. Munakata-taisha dates back to the 4th century, where sailors prayed for safe voyages across the seas. You’ll find national treasures like a golden ring and a bronze mirror that speak to ages past.  So sacred only Shinto priests are allowed to enter, the island of Okinoshima, home to one of the three shrines, is now a UNESCO World Heritage Site.
