[2025–2026] Must-Know Info on Music Festivals & Outdoor Events in the Koshinetsu and Hokuriku Regions

An outdoor festival hosted by the Yamanashi-born band THE NO EAR. It takes place at Kami-Suta Plaza in Yamanashi Prefecture, a venue with traditional Japanese-style buildings that gives it a wonderfully atmospheric feel. The rock-centered live performances held there create an extraordinary vibe, and it looks like it’s going to be a truly lovely event.

Named after the phrase “Kaga Hyakumangoku,” Million Rock lives up to its name as the largest rock festival in the Hokuriku region. With a solid, festival-worthy lineup, it brings excitement every year. Its major appeal is the large roster of stellar artists.

Gosetsu JAM was launched in Tokamachi, Niigata—the event venue—after organizers asked, “What can we do to draw people here?” and decided on a music festival. There probably aren’t any other outdoor festivals held in such a heavy-snow area, are there? With humorous rules like “Moshing and stage diving prohibited; oshikura manju (friendly shoving) allowed,” it sounds like a really fun event.

GREEN FLASH Fes is held at a resort facility in Fukui Prefecture, set against the backdrop of the sea. A “green flash” is the moment when a green light appears as the sun sinks into the ocean, and legend has it that seeing it brings good luck. With your favorite music as the soundtrack, it’s an event where participants can spend their time freely—lying on the grass while gazing at the vast sky and ocean, or enjoying delicious food. There’s also a fully equipped campground nearby, so how about adding it to your travel plans?
