Inujima (犬島, [inɯdʑima], lit. "Dog Island") is a Japanese island in the Seto Inland Sea, located near the coast of Okayama Prefecture. It is part of Higashi-ku, Okayama.^[1]

As of 2017^[update], Inujima has a population of 47.^[2]

A ferry service operates between Hōden and Inujima.^[3]

A copper refinery was opened on the island in 1909, but this closed in 1919.^[2] The brick-built refinery remained largely undemolished, and from 2008, it formed the centrepiece of a large-scale art project designed to stimulate tourism to the island.^[4]

The Inujima Art Project (犬島アートプロジェクト) is a rehabilitation project covering the entire island by the Naoshima Fukutake Art Museum Foundation, a project of Benesse Corporation. It opened to the public in April 2008. The first phase of the project was to turn the old seirensho refinery into a model of contemporary architecture and art to recycle the Japanese industrial heritage. It was the coordinated efforts of the architect Hiroshi Sambuichi and Yukinori Yanagi who collaborated with the architect in his artwork, and the Faculty of Environmental Science and Technology at Okayama University.^{[citation needed]}
