Shōdoshima is a town in Kagawa Prefecture, Japan, with a population of 13,646. The town was established in 2006 and covers various ports and communities on the eastern half of Shōdoshima, the second-largest island in the Seto Inland Sea. Shōdoshima is roughly halfway between the much larger islands of Shikoku to the south and Honshu to the north, and has a mild and relatively dry climate.
Soy sauce production, which flourished through the early 20th century, remains a major industry. Other industries include sōmen noodles, tsukudani, fishing and agriculture. In Japan, olives were first successfully cultivated here in the 1910s and olive oil production resurged in the late 20th century.
Tourism is also economically important. Shodoshima participates in the Setouchi Triennale, a regional art festival, and the mountainous interior is home to Kankakei Gorge. The book and film Twenty-Four Eyes was set on the island, and a movie studio park and museum attracts visitors.
