In 1893, Mikimoto Kōkichi, a local entrepreneur, succeeded in producing cultured pearls on an island in Ise Bay called Ojima (相島).
It was resold to Mikimoto Kōkichi in 1929, with the funds used to establish an elementary school.
Mikimoto developed the island as a center for pearl production.
Among its exhibits is a reproduction of the udon shop "Awakō" (阿波幸), where he was born.
The island also contains a bronze sculpture of Mikimoto Kōkichi, the Shrine of Pearl, the Forest of Wild Birds and Observatory, the restaurant "Awakō," and a pearl shop.
