Music Festival Master / Editor-in-ChiefKeisuke Hane
Editor-in-chief of RAG MUSIC and in charge of music festivals. When I attended my first music festival as a freshman in college, I was captivated by its charm—“I can’t believe there’s a place this free and this fun.” I share information about wonderful music festivals every day to help grow the community of festival fans.

From large-scale festivals to smaller ones, there are now countless exciting festivals being held.

Especially in summer, there are so many that it’s hard to keep up with all the information.

Here, we’ve compiled a list of summer music festivals taking place in eastern Japan.

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.

Schedule	Sat, May 31, 2025 – Sun, June 1, 2025
place	Outland, Tōkamachi City, Niigata Prefecture
