Ōzukumi-jima
Ōzukumi-jima is mentioned in the Heian period "Wamyō Ruijushō ". Archaeologists have found shell middens and the remains mid-Yayoi period pit houses and ceramics on the islands, indicating that it was inhabited in antiquity, but the island is not known to have been inhabited in historic times. The waters surrounding Ōzukumi-jima are noted for the commercial fishing of shrimp and octopus. Local fishermen hold a Shinto ceremony on the island annually in July.
