Inujima Island is a small art island located in the Seto Inland Sea of Japan, part of Okayama Prefecture. The island covers approximately 0.54 square kilometers and is home to fewer than 50 residents, making it one of the smallest inhabited islands in the region. Its name translates to "Dog Island," reportedly derived from a dog-shaped rock formation visible from the sea.
The island's defining feature is the Inujima Seirensho Art Museum, designed by architect Hiroshi Sambuichi and opened in 2008. This innovative museum repurposes the ruins of a copper refinery that operated briefly from 1909 to 1919 during Japan's industrial modernization period. The refinery's history, though short-lived, left behind dramatic brick chimneys and industrial structures that now form the museum's architectural foundation. The museum exclusively displays work by artist Yukio Mishima, integrating art installations with the historical industrial remnants in a powerful commentary on modernization and nature.
Inujima became part of the Setouchi Triennale contemporary art festival, which takes place every three years across multiple islands in the Seto Inland Sea. Beyond the main museum, visitors can explore the Inujima Art House Project, a collection of art installations housed in traditional homes scattered throughout the island's village. These intimate galleries blend contemporary art with the island's residential architecture, creating an immersive cultural experience. The island's compact size makes it easily walkable, allowing visitors to experience both the art installations and the quiet rural atmosphere in a single visit.
Inujima is accessible by ferry from Hoden Port in Okayama, with the journey taking approximately 10 minutes. Alternative ferry routes connect from Teshima Island and Naoshima Island, making it possible to visit multiple art islands in one trip. Admission to the Inujima Seirensho Art Museum costs 2,100 yen for adults, while the Art House Project requires a separate ticket of 2,100 yen. A combined ticket for both attractions is available at 3,150 yen. The island has minimal facilities, with one café and limited dining options, so visitors should plan accordingly.
