Naoshima is the name most people know. It appears in architecture magazines, on luxury travel lists, and in the itineraries of design-conscious travelers who have been to Japan more than once. What fewer people know is that Naoshima is one point in a wider constellation of islands across the Seto Inland Sea, and that the neighboring islands of Teshima and Inujima hold work that far fewer visitors have seen.
This is a guide to the full trail: what each island offers, how to move between them, and why the best time to visit is not during the Triennale.
THE THREE ISLANDS
Naoshima is the anchor of the Seto Inland Sea art world. The Chichu Art Museum, designed by Tadao Ando and built entirely underground, contains a small, permanent collection: five paintings by Claude Monet, two installations by James Turrell, and one by Walter De Maria. The building is as much the work as the art within it; the relationship between the concrete forms and natural light is the primary experience.
The Benesse House complex combines hotel accommodation with a permanent contemporary art collection displayed throughout the building and its grounds. Lee Ufan Museum, also by Ando, holds a focused collection of the Korean-Japanese artist's minimalist work. The Art House Project in Honmura village repurposes traditional Japanese houses as site-specific art installations.
Teshima is a small agricultural island with terraced rice fields and views across the inland sea. Its defining work is the Teshima Museum, a single-room concrete shell designed by architect Ryue Nishizawa (co-founder of SANAA) that houses one installation by artist Rei Naito. The work, titled Matrix, involves water droplets emerging from the floor, moving slowly across the surface in response to air currents, combining and separating. Two oval openings in the roof and wall frame the surrounding landscape.
Visitor numbers are strictly limited and the space is experienced in near-silence. Nothing separates the work from the weather outside, so what you see depends on the hour you arrive.
Inujima is the smallest and least visited of the three main art islands. The Seirensho Art Museum was created by transforming the ruins of a copper smelting facility that operated from 1909 to 1919. Architect Hiroshi Sambuichi designed the museum to use the heat and airflow of the existing chimney stacks as a natural climate control system. Artist Yukinori Yanagi created a permanent installation that incorporates fragments of the poet Yukio Mishima's demolished house.
A ruined copper smelter, a passive cooling system and a work built from Mishima's demolished house share one building. Inujima rewards a slow visit, and most itineraries do not leave room for one.
THE TRIENNALE QUESTION
The Setouchi Triennale is held every three years: most recently in 2025, next in 2028. During Triennale years, Naoshima and Teshima experience significant visitor surges. Ferry queues at Uno Port extend for hours. Accommodation books out months in advance. The quiet that brings people to these islands is the first thing a Triennale year removes.
Off-years, 2026 and 2027, are the quiet ones. The permanent collections at Chichu, Teshima Museum and Seirensho stay open, the ferries run to their normal timetable, and Benesse House accommodation is available.
"The Teshima Museum on a quiet Tuesday in October, with three other visitors, is a different experience from the same space during the Triennale. The work hasn't changed. Everything else has."
MOVING BETWEEN ISLANDS
The public ferry network connects Uno Port to Naoshima (approximately 20 minutes), Teshima (approximately 35 minutes), and Inujima (approximately 50 minutes via Teshima). The schedules are manageable but not frequent. Missing a departure typically means a 60–90 minute wait for the next.
Private boat charter from Uno Port removes that constraint. A chartered vessel moves between the islands on your schedule, so you can stay an extra hour on Teshima or leave Inujima early without losing the rest of the day. For groups of four or more, the cost is usually repaid in time.
Accommodation on Naoshima at Benesse House, the only hotel inside the Benesse Art Site, books well in advance. If you want more than a day trip, book it before anything else in the itinerary.
HOW STAYGO APPROACHES THE ISLANDS
STAYGO books Benesse House, arranges the private boat, and plans the three islands in an order that gives each one the hours it needs. Ferry windows, timed museum entry and the shortage of rooms are settled months before you travel, which is when the work has to be done.
For guests combining the Seto Inland Sea with time in Kyoto or Osaka, the geography is more convenient than it appears: Okayama is a single Shinkansen stop from Shin-Osaka (17 minutes), making the islands a natural addition to any western Japan itinerary.
THREE ISLANDS, PLANNED AS ONE TRIP
STAYGO arranges the Benesse House room, the boat between islands and the timed museum entries, and fits them to the days you have.
