ToggleWhat is the Setouchi Triennale?
The Setouchi Triennale Festival was first introduced in 2010. The name Setouchi comes from the region where the festival occurs, and “Triennale” means it happens once every three years. The festival is about contemporary art, which means new and creative ways of expressing ideas. But it’s not just paintings or sculptures; it also includes things like music, plays, food, buildings, and local crafts.

Artists from Japan and many other countries join this festival and create works shown on the islands, in the forests, on the beaches, and inside old houses. Some art pieces are outside, blending with trees or looking out over the sea. Others turn old homes into surprising art spaces. Many of these creations stay even after the festival ends, so visitors can enjoy them anytime.
Setouchi Triennale was created to help bring new life to small island communities that had become quiet over time. Many people had moved away, and the villages were growing older. The festival hoped to bring back joy and visitors and create a strong connection between people and their beautiful natural surroundings through Japanese art.

Each island in the Setouchi region offers something special. On Naoshima, a new museum opening May 31 will feature Asian contemporary art with sea views. Teshima Art Museum invites quiet reflection with its water-inspired space. Megijima transforms a swimming pool into a colorful town of books and blocks.
