In the 1970s, Naoshima was a different kind of island. A smelting company called Mitsubishi Materials had built operations there, and when the industrial logic that had sustained the presence collapsed, it took the economic reason for staying with it. What remained was a beautiful island in the Seto Inland Sea with a rapidly aging population, young people leaving for the mainland, and the particular silence of a community watching itself diminish. Nobody in 1970 was talking about Naoshima as an art destination. Actually, nobody was talking about it at all.
That changed because one man asked a question he refused to stop asking. Soichiro Fukutake, the billionaire chairman of Benesse Holdings, arrived on these islands in the 1980s and saw what he later described without euphemism: beautiful landscapes, communities with deep traditions, younger generations leaving for cities. His question was direct and enormous. Could contemporary art reverse this? The answer to that question is now the Setouchi Triennale — the largest art festival in Japan, a model studied and replicated across the world, and the reason the Seto Inland Sea is one of the most quietly extraordinary cultural destinations on the planet.
The Sea That History Ran Through
The Seto Inland Sea is not empty water between islands. For centuries it was the vital corridor through which Japan moved goods, culture, and people. Korean delegations crossed it, linking an isolated Japan to the culture of the Asian continent. From the 17th century onward it was the primary transport route carrying goods from northern Japan to Osaka. Clans fought for centuries over control of its resources. In 1934, the section of the Inland Sea bordered by Kagawa, Okayama, and Hiroshima prefectures became Japan’s first national park.
Then the sea’s position changed. Industrial pollution and toxic waste from rapid 1960s economic growth degraded the environment. Globalization rationalized the island economies out of relevance. Populations declined. Communities aged. The Seto Inland Sea became politically isolated and fragmented — a place that had provided vital connection and then found itself severed from the flows it once controlled. Teshima lost two thirds of its residents between 1950 and 2010, not through any dramatic process. It was the slow arithmetic of young people making rational decisions about where to build a life.
Fukutake Arrived With a Philosophy, Not a Festival
Fukutake did not arrive with a festival in mind. He arrived with a philosophy. His operating principle — that economy is subordinate to culture — sounded abstract but he spent decades making it structurally true. He began on Naoshima. A campsite in 1985.
Then, working with architect Tadao Ando, the Benesse House Museum in 1992 — the first museum on the island, designed to exhibit works from Fukutake’s collection, positioned so that the building, the art inside it, and the landscape outside it were in continuous conversation with each other.
Ando’s concrete geometry became the visual language of the islands. The Chichu Art Museum followed in 2004 — built almost entirely underground, with natural light as its primary architectural instrument, housing site-specific installations by Walter de Maria and James Turrell alongside four works from Claude Monet’s Water Lilies series. The Lee Ufan Museum came next. The Art House Project, running since 1998, commissioned architects and artists to restore abandoned homes across Naoshima’s Honmura district and reinvent those spaces through artistic intervention. Karel Appel’s Frog and Cat had arrived in 1989 as the first work installed on the island as part of the Benesse Art Site project.
On Teshima, the Teshima Art Museum — designed by Ryue Nishizawa with an interior installation by Rei Naito titled Matrix — opened in 2010. On Inujima, a former copper refinery became the Seirensho Art Museum, its industrial ruins the raw material of the artistic programme. Yayoi Kusama’s polka-dotted Pumpkin settled on a quiet Naoshima pier. The Benesse Art Site Naoshima grew to encompass more than 21 sites and projects across Naoshima, Teshima, and Inujima — collectively one of the most significant privately funded art destinations in the world, and the foundation on which the Triennale was built.
The Festival Arrived in 2010 and Surpassed Every Expectation
By the early 2000s, Naoshima was drawing international attention that the island’s infrastructure was struggling to absorb. The question of how to distribute that energy — and extend the revitalisation logic to the other islands — produced the Setouchi Triennale. Fram Kitagawa, one of Japan’s most prominent art directors, brought the model he had already proven with the Echigo-Tsumari Art Triennial in Niigata Prefecture, launched in 2000. He had demonstrated that art could move people into rural areas in significant numbers and leave behind something more durable than tourism revenue. Kitagawa became General Director. Fukutake became General Producer. The first edition launched in 2010 and surpassed every expectation set for it.
The Triennale is not managed by the Fukutake Foundation. This distinction matters. It is organised by the Setouchi Triennale Executive Committee, under the presidency of the Governor of Kagawa Prefecture. The festival draws on the infrastructure Benesse built and extends far beyond it — across Megijima, Ogijima, Shodoshima, Oshima, and beyond — islands where there are no grand museums or luxury hotels, no Ando concrete and no Kusama pumpkins, just fishing communities, olive groves, and artists making site-specific work in direct response to the grain of each place.
2025 Edition: 17 Islands, Undiluted
The Triennale runs for approximately 107 days spread across spring, summer, and autumn sessions. It is not a single concentrated event. It is a structured encounter with the same geography across different conditions of light, temperature, and season. Spring brings the Inland Sea before the heat arrives — clear mornings, the islands at their most cinematically precise. Summer means the full weight of the Japanese summer: intense, humid, the sea gleaming under a sky that offers no shelter. Autumn brings cooler crossings, colour change, a different pace.
The 2025 edition — the sixth — ran across 17 islands and coastal areas. Spring: April 18 to May 25. Summer: August 1 to August 31. Autumn: October 3 to November 9. Nine locations participated across all three seasons: Naoshima, Teshima, Megijima, Ogijima, Shodoshima, Oshima, Inujima, the Takamatsu Port area, and the Uno Port area. Additional locations joined for single sessions — the Seto Ohashi Bridge area in spring, the Shido and Tsuda area and Hiketa area in summer, and Honjima, Takamishima, Awashima, Ibukijima, and the Utazu area in autumn. Artists from 21 countries presented over 150 exhibitions. The spring season alone drew 320,000 visitors across its 38 days.
The 2025 edition also introduced the Naoshima New Museum of Art — designed by Tadao Ando, one storey above ground with two underground floors and four galleries, sitting on a hilltop near the small port of Honmura. Its director, Akiko Miki, described it as the first museum located within a village on the island — rooted in local community yet open to the world. Its programming shifted focus toward contemporary art from Asia, correcting the almost entirely Japan-and-West axis that had characterised the Benesse Art Site’s existing institutions.
What Site-Specific Means Here, and Why It Matters
Site-specific is a term that gets used so broadly it can mean almost nothing. At Setouchi, it means something precise. Artists arrive on islands and spend time in communities before making anything. The work that results is not art transported to a neutral setting. It is art grown from the specific conditions of each place — its history, its architecture, its people, the texture of light off the water at a particular hour. Abandoned homes become galleries. Former industrial buildings become installations. The Art House Project on Naoshima has been doing this since 1998 with commissions in which architects and artists restore derelict structures and make the restoration itself an artistic act.
On islands like Ogijima — its village perched on a steep slope connected by labyrinthine lanes — and Shodoshima, the largest island in the Triennale, this approach is the entire model. Visitors arrive by ferry, walk through fishing villages, and find work installed in the ordinary fabric of a working community. Oshima carries its own specific weight — an island with a history of Hansen’s disease segregation, where the Triennale’s programming deliberately engages that history rather than aestheticising over it. Megijima, twenty minutes by ferry from Takamatsu, is an island of ogre legends and high stone walls. Each island arrives with its own argument. The Triennale’s job is to find artists capable of answering it.
The overarching theme is the Restoration of the Sea — a phrase carrying both ecological and cultural meaning. The sea that was once isolated and degraded is being reconstituted as a space of hope, exchange, and imagination. The festival has demonstrably reversed population decline on some of the islands it activates. Newcomers have settled in communities that were emptying. Local economies have restructured around the cultural traffic the Triennale generates.
How to Move Between Islands Without Losing the Plot
The all-season passport for the 2025 Triennale was priced at ¥5,500, available through the official Setouchi app, travel agencies, and information centres on the islands. The passport covers one-time access to each participating artwork and facility across all three sessions. It does not cover the Chichu Art Museum or the Teshima Art Museum, which charge separately. Individual artworks can be paid for without a passport, though for any visitor planning multiple islands across more than one session, the passport is the rational choice.
Navigation runs on public ferries out of Takamatsu Port and Uno Port. Ferries to Naoshima from Takamatsu run approximately hourly, taking 30 to 50 minutes at ¥520 to ¥1,220 one way. Naoshima has closures — typically Mondays — and not all installations are open every day. The official artworks calendar tracks exactly this. Official public tours in English are available for first-time visitors. The more experienced Triennale traveller island-hops independently with the app, the ferry schedule, and specific works already targeted.
Naoshima is the right island if time allows only one — the density of permanent work sustains a full day without the Triennale schedule even being a factor. For visitors with more time, the sequence of Naoshima, Teshima, and then one smaller island — Ogijima or Shodoshima — gives the fullest range of what the Triennale actually does. The polished and permanent against the temporary and unexpected. The grand architectural statement against work installed in a fisherman’s house.
The 2025 edition concluded in November. The next Triennale takes place in 2028. Permanent and long-term works from previous editions remain on display through the year — the artworks calendar tracks what is accessible outside festival season.
