On the Setouchi Inland Sea in Japan, where nearly 3,000 islands dot the blue water between three major Japanese islands, a remarkable experiment in community renewal has been unfolding for more than a decade. The Setouchi Triennale is a massive art festival held once every three years, spanning over 100 days across 12 different islands. Artists install sculptures, transform abandoned buildings, and create spaces that draw visitors from around the world. But behind the spectacle of art and tourism, researchers have been asking a crucial question: can these festivals actually help island communities thrive long-term, or do they just create a temporary boom followed by silence?
Meng Qu, an associate professor at Hiroshima University's Graduate School of Humanities and Social Sciences, spent 10 years finding out. She studied three installments of the Triennale, surveying 128 small tourism businesses and interviewing hundreds of residents and business owners across five islands: Naoshima, Teshima, Inujima, Ogijima, and Megijima. Her findings, published in the Journal of Marine and Island Cultures on April 30, 2026, reveal both the promise and the challenge of using art to revive struggling island communities.
The numbers during festival time are striking. Millions of visitors stream to these remote islands during the 100-day event. But between festivals, foot traffic drops dramatically. For isolated island communities with limited resources, this boom-and-bust cycle can be exhausting and even harmful. "While rural art festivals facilitate temporary vitality, long-term archipelagic resilience requires a shift from urban-centric economic metrics toward a model that values moderate interaction and spatial justice," Qu writes.
Previous research on the Triennale focused only on Shodoshima, the largest and most economically stable island in the region. Qu's study broke new ground by examining the smaller, more vulnerable islands that face greater struggles with aging populations and out-migration.
The study's central insight is hopeful but nuanced: art festivals can indeed support long-term revitalization, but only when communities move beyond simply riding the wave of outside visitors. Local leaders must take ownership of the festival's legacy, building relationships and infrastructure that benefit residents year-round. Qu argues that success depends on balancing "festivalness" with what each community can actually sustain—its resource limits and social capacity to absorb change.
What does this mean for the 12 islands of the Setouchi region? Qu suggests that similar "art island" models around the world should be evaluated not as isolated experiments, but as part of a connected network of communities sharing resources and lessons. The goal is not to transform islands into theme parks, but to strengthen the roots already there. "Instead of relying solely on exogenous factors brought by art intervention, the central role of rural art festivals must be examined through community-level response and endogenous efforts," she concludes.
For islands facing decline, the message is clear: art can be a powerful tool, but the real magic happens when locals become partners in the process, not just hosts.
