Setouchi Triennale 2025

Held once every three years, the Setouchi Triennale is one of Japan’s most exciting art festivals, taking place across 17 islands and port towns in the Seto Inland Sea. Running across three seasonal sessions: Spring (Apr 18–May 25), Summer (Aug 1–31) and Autumn (Oct 3–Nov 9), this festival blends innovative art with local culture, scenic travel and island life.

With over 150 site-specific artworks spread across multiple islands, the Setouchi Triennale is one of the world’s most ambitious contemporary art festivals. It brings together internationally acclaimed artists, visionary architects and local communities to create immersive works rooted in place.

While the festival spans the broader Seto Inland Sea, many of the most iconic locations include:

• Naoshima: The heart of the Triennale, home to Yayoi Kusama’s Red Pumpkin, the waterfront Benesse House Museum and the Chichu Art Museum. 
• Teshima: Known for the dreamlike Teshima Art Museum, where silence, architecture and landscape merge into a meditative experience.
• Inujima: Once an industrial site, now an art island embracing themes of sustainability and transformation.
• Shodoshima & Oshima: Places where rural life, local stories and regional heritage become part of the art itself

The Setouchi Triennale is also about showcasing all there is to love about the region. Thanks to the area’s mild climate and abundant natural resources, Setouchi Cuisine is another highlight of the triennale. Fresh seafood, seasonal vegetables, handmade noodles and citrus-based delicacies can be enjoyed across the islands. From cozy cafes to volunteer-run restaurants, enjoying Setouchi cuisine becomes part of the creative journey.

Things To Do

One of the joys of the Setouchi Triennale is that getting there is part of the experience. Base yourself in Takamatsu, the festival’s main gateway, with regular ferry routes to major islands like Naoshima, Teshima, Shodoshima, Megijima and Ogijima. Fares typically range from ¥300 to ¥1,500 one way, depending on the destination.

From Uno Port on the Okayama side, you can also reach Naoshima, Inujima and more. Ferry timetables vary by season, so check ahead, especially around Obon, when the islands are forecast to be crowded.

Every island offers something a little different. Shodoshima is known for its olive trees, the romantic Angel Road tidal path and the scenic Nakayama Rice Terraces. Megijima has dramatic sea caves and legends tied to the Momotaro folk tale. Oshima and Inujima offer slower-paced strolls through quiet villages and eco-focused installations.

When you’re not gallery-hopping, take time to enjoy Takamatsu’s attractions. Wander through the historic Ritsurin Garden or explore the ruins of Takamatsu Castle. In summer, you can also cool off at nearby beaches, including Chichibugahama.
