Seto Inland Sea Islands: Treasure Islands That Kagawa is Proud of

In the Seto Inland Sea offshore Kagawa Prefecture, distinctive islands including Shodoshima, Teshima, Megijima, Ogijima, and Naoshima are dotted throughout. Floating on a calm sea, these islands draw worldwide attention as venues for the Setouchi Triennale, held once every three years, and form an area where art, nature, and island life blend in harmony. Hopping from island to island by ferry or high-speed boat is a journey full of the special charm of the Seto Inland Sea, drawing countless travelers.

Islands Reborn Through Art

The islands once faced depopulation and aging, but through a project turning entire islands into stages for contemporary art, they were reborn as areas sending out new appeal. Old private houses and disused buildings were regenerated as artworks, creating original spaces that merge with the islands scenery and history. The Setouchi Triennale brought many visitors from Japan and abroad, restoring vitality to the islands. They are widely known as a successful case of regional revitalization in which the value of island life and nature was rediscovered through art. Many works sit quietly outdoors or within the villages, so casual chats with residents and simply walking the lanes become part of the journey.

Island Hopping Full of Character

Each island has its own personality. The largest, Shodoshima, is known for olive cultivation, soy sauce brewing, and as the setting of the film Twenty-Four Eyes, and offers the ravine beauty of Kankakei. Teshima gathers museums where nature and architecture merge, while Megijima is famous for its demon legend and a large cavern. Ogijima is a port town of pretty slopes and stone walls, with artworks scattered through the settlement. Naoshima, a main venue of the festival, brings together high-quality contemporary art such as the Chichu Art Museum and Benesse House, making the whole island feel like an open-air gallery. Because each island offers different art, scenery, and food, connecting ferries to visit several is recommended. The sea voyage across calm waters is itself a great appeal of a Setouchi journey.

Enjoying the Seasons

Mild spring and autumn are ideal for island hopping, but the islands can be enjoyed year-round. Spring brings flowers and fresh greenery, summer offers sea leisure and refreshing breezes, autumn gives clear-air views of the many islands, and winter offers quiet island time with fewer crowds. The Setouchi Triennale is usually held across three sessions in spring, summer, and autumn; sessions bring more works and better access but crowd the islands and boats. Many islands display permanent works outside session periods too, so quieter visits are actually recommended for those seeking calm.

Access and Basic Information

The base for island hopping is Takamatsu Port, with ferries and high-speed boats to Naoshima, Teshima, Shodoshima, Megijima, Ogijima, and others. Naoshima and Teshima can also be reached from Uno Port in Okayama Prefecture, convenient from Honshu. Travel times vary by destination and service, roughly from tens of minutes to about an hour from Takamatsu. On the islands, travelers get around by community bus, rental bicycle, electric-assist bike, or on foot. Some islands have few sailings, so confirm timetables including the last boat back, not only the outbound trip.

Practical Travel Notes

• Limit yourself to one or two islands a day. Cramming in more eats into sightseeing time with transfer waits; slow walking reveals far more of each islands charm.
• Ferry times and last boats. Some islands have few sailings, and missing the last boat can strand you. Always note both outbound and return times.
• Carry cash. On small islands, eateries and shops may accept cash only. Bring plenty of small bills and coins.
• Closing days and festival passport. Museums often close on Mondays or other days, and popular sites may need reservations. During the Triennale a combined admission passport is cheaper.
• Comfortable gear. Many islands have slopes and unpaved paths. Wear comfortable shoes and bring sun protection and, in summer, plenty of water.
• Island manners. Many works and lanes sit beside residents daily life. Do not enter private land or fields, and view quietly.

A Word of Advice

An island trip in the Seto Inland Sea is the kind of journey where riding the boat is itself a destination. Rather than forcing in many islands, slowly walking one or two while savoring village life and sea air makes for the most rewarding day. Session and sailing details change easily, so check the latest information from Takamatsu Port and each operator before you set out.
