Setouchi Triennale

The Setouchi International Art Triennale is a contemporary art festival held every three years on several islands in the Seto Inland Sea of Japan and the coastal cities of Takamatsu and Tamano. The festival was inaugurated in 2010 with the aim of revitalizing the Seto Inland Sea area, which has suffered from depopulation in recent years, as well as long-standing environmental degradation from illegal industrial waste-dumping practices conducting during the 1970s following rapid industrialization in the area.^{[1][2]: 218}

Initiated as a public-private partnership between the local prefectural and municipal governments and education publisher Benesse, the festival focuses on artistic endeavors that highlight local communities and environmental conditions, as well as site-specific installations that make use of existing spaces and ecological features. The festival has played a significant role in the growth and redevelopment of the region, serving as a leading example of the potentials of reinvestment in peripheral communities in decline after the explosive growth of major cities in Japan during the second half of the 20th century.

The Triennale lasts for eight months with three main sessions; the spring session runs from March to mid-April, the summer session runs from mid-July to early September, and the autumn session runs from October to early November.^[3][4] While several of the museums and installations are permanent exhibitions, many of the smaller islands offer temporary exhibitions limited to a single session. Notable permanent fixtures include a series of concrete museums on Naoshima designed by architect Tadao Ando, as well as the Teshima Art Museum (2010), designed by Ryue Nishizawa featuring Rei Naito's Matrix, and the Art House Project (1998-present) on Naoshima, a series of commissions involving architects and artists who restore abandoned homes and other buildings and reinvent the spaces through artistic intervention.
