A Private Company Builds a City

Nagasaki Stadium City opened on 14 October 2024 in Koto-machi, central Nagasaki, representing one of Japan’s most ambitious privately funded urban developments in recent memory. Developed and operated entirely by Japanet Holdings — the mail-order and media conglomerate that also owns Nagasaki’s J.League football club, V-Varen Nagasaki — the complex was built at a cost exceeding ¥100 billion without reliance on public funding. Total floor area is approximately 194,000 m². At its heart are Peace Stadium, a 20,000-seat football-specific venue, and a 6,000-seat multi-purpose arena. Design and construction were led by Takenaka Corporation, Toda Corporation, Environmental Design Institute, and Yasui Architects & Engineers.

What sets Nagasaki Stadium City apart from a conventional sports venue is its explicit ambition to function as a neighbourhood rather than an event facility. Commercial areas, co-working offices, and an international-grade hotel are woven through the complex so that it remains active on non-match days. The stadium turf management, arena floor configurations, and wayfinding were all designed with year-round operational efficiency in mind.

Sport-Led Urban Regeneration in a Regional City

In Japan, sports stadia and arenas are typically built with public investment, making Nagasaki’s all-private model a closely watched experiment. The city’s central district had long struggled with ageing building stock and declining footfall, and the scale of Japanet’s investment — over ¥100 billion at a single address — has raised expectations of a wider ripple effect across adjacent commercial and business districts. The arena also serves a B.League basketball club, and its flexible floor plan targets concerts, combat sports, and exhibitions to keep occupancy high outside the sports calendar.

Summary

Nagasaki Stadium City opened in October 2024, covering approximately 194,000 m² with a 20,000-seat football stadium, a 6,000-seat arena, a hotel, retail spaces, and offices — all financed and managed by Japanet Holdings with over ¥100 billion of private capital. The project demonstrates that sport-led, privately funded urban regeneration is achievable at scale in a regional Japanese city, and the new flows of people it has generated at the heart of Nagasaki are already reshaping the neighbourhood around it.
