Located amid the calm waters of the Seto Inland Sea, Teshima island has an area of 14.5 km² and a population of about 800 inhabitants. The spring water from Danyama, a mountain rising in the center of Teshima, has supported farming and life on the island since long ago. When dairy farming was prospering on the island, Teshima used to be known as “the island of milk.” It was also nicknamed “the island of welfare” due to the pioneering welfare facilities built on the island before the war. Illegal dumping of industrial waste, which begun in the 1970s became one of the biggest waste scandal nationwide. The disposal and treatment thereof is underway, and the islanders vigorously engage in the environmental restoration of the island.Starting with the opening of Teshima Art Museum in 2010, contemporary art is now steadily attracting large numbers of visitors from Japan and abroad.
