Naoshima is the main island of a township made up of twenty-seven islands administered by Kagawa Prefecture. The island has a documented history going back to the Heian period, but today it’s known for its contemporary art museums, which draw visitors from all over the world, especially during the Setouchi Triennale art event held every three years in the region. Since the island is part of the Seto Inland Sea National Park, there are strict rules for the visual impact of new buildings, so many of the art museums are built into the ground, creating an interesting aesthetic of their own. ・One day trip from Osaka ・You can enjoy to go around Naoshima island by bicycle (with power-assisted bicycle, e-bike) .
