Inujima (Dog Island) is the smallest and least-visited of the Setouchi art islands — a 0.54 sq km island just off the Okayama coast, reachable from Hoden Port in 10 minutes. Its population has dwindled to under 50 permanent residents; its abandoned copper refinery ruins from the early 20th century became the foundation for the island’s only major art institution, the Seirensho Art Museum — one of the most intellectually ambitious art-and-architecture projects in Japan.
Seirensho Art Museum (犬島精錬所美術館)
Built within the ruins of the 1909 copper refinery (which operated for only 10 years before copper prices collapsed), the Seirensho Art Museum incorporates the chimney stacks, brick walls, and industrial infrastructure of the original refinery into the exhibition space. Architect Hiroshi Sambuichi designed the building around a passive energy system using no external power — the chimney structures and underground channels create natural ventilation and temperature control through solar and thermal dynamics. The permanent installation by artist Yukinori Yanagi explores the theme of Japan’s Meiji-era modernization through the prism of Mishima Yukio’s writings, using the refinery’s transformation of raw copper as metaphor. Entry ¥2,100 (includes Art House Project). Open Thursday–Tuesday; closed Wednesdays and December–February.
Art House Project — Inujima
Five small-scale installations embedded in the island’s abandoned residential buildings complement the main museum. The installations are small and intimate — each occupying a single converted house — and the walking route between them through the quiet village streets (crumbling walls, overgrown gardens, cats sleeping on warm stone) is itself a form of site-specific art experience. The island’s demographic decline is made visceral without being exploited for tourism effect.
Getting to Inujima
- From Hoden Port (Okayama): 10-minute ferry (¥580 round trip). Hoden is accessible by bus from Okayama Station (40 min, ¥540) or Tsujiuchiza bus stop.
- From Teshima: Ferry connection during Setouchi Triennale sessions; limited service outside Triennale years.
- Note: Inujima’s ferry schedule is limited (typically 5–6 crossings per day); plan carefully to avoid missing the last return ferry. Check current schedules on the island ferry operator’s website.
The Island Experience
Inujima is Naoshima’s opposite in almost every way: tiny, quiet, unfamiliar to most visitors, and deeply melancholy in the best sense. The refinery ruins overgrown with vegetation, the nearly empty village streets, the cats, and the sound of the sea make the art experience inseparable from the place. This is the Setouchi art island network at its most challenging and most rewarding — not a museum destination but an encounter with landscape, industrial history, and the concept of place itself as artistic medium. Allow 2–3 hours on the island; combine with Teshima or Naoshima as a same-day or next-day pairing.
