■HAPPINESS JAM 2025 in HAPPINESS ARENA will be held on (Sat), September 6, 2025
HAPPINESS JAM, Nagasaki's first large-scale indoor music festival bringing together J-pop artists, will be held on (Sat), September 6, 2025 at the Happiness Arena in Nagasaki Stadium City, a large complex with an area approximately 1.5 times the size of the Tokyo Dome.
A variety of today's leading J-pop artists will gather at Happiness Arena. Artists that can be enjoyed by people of all ages, from children to adults, will gather to deliver a one-day-only special stage performance.
Nagasaki has long been known as a hub for intercultural exchange, and has developed through the intermingling of various cultures and entertainment. With the charm of Nagasaki as a historic international city as a backdrop, this one-of-a-kind event will fuse the Happiness Arena with the dynamism of J-pop under the concept of "A special day filled with happiness, connected by music." The event will allow visitors to experience various forms of "happiness," not just music, but also food, entertainment, and connections with people. In the future, the event aims to utilize the entire facilities of Nagasaki Stadium City, including the soccer stadium and hotels.
