Gunma Music Festivals [2026]: Outdoor Festivals and Event Roundup

Music Festival Master / Editor-in-ChiefHane Keisuke
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.

We’ve put together a roundup of music festivals in Gunma Prefecture, including summer festivals, rock festivals, and outdoor festivals.

We look forward to welcoming you again this year at exciting events like I ROCKS, New Acoustic Camp, and YAMABITO Ongakusai (Yamabito Music Festival)!

Yamabito Music FestivalSat 9/20 – Sun 9/21, Gunma Prefecture

The Gunma Rock Festival, which was held for three years starting in 2011, has been reborn as “Yamabito Ongakusai.” The central driving force behind the event is G-FREAK FACTORY, and the title “Yamabito” (mountain folk) was chosen to evoke Gunma Prefecture’s mountains: Mt. Akagi, Mt. Haruna, and Mt. Myogi.
