This pier-like shrine extending over the tidal flats traces its origins to the late 6th century, with its present form dating from 1168 when it was rebuilt under the patronage of the doomed Heike clan. The entire structure seems to float at high tide, an effect so magical that commoners were once forbidden to set foot on the island and had to approach by boat through the torii gate. On one side, a floating nō stage built in 1680 still hosts performances every April. Come at high tide for the full effect, or at low tide for a completely different perspective as you walk across the exposed flats.
