List of Rock Festivals in Koshinetsu [2026]

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’d like to introduce music festivals in the Koshinetsu region that focus on rock.

While Fuji Rock, arguably Japan’s most famous festival, takes place in the Hokuriku region, there are also other rock festivals recommended for fans of Japanese rock.

Past events

Iwamurock FESTIVALNiigata Prefecture, Sat 9/20 – Sun 9/21

iwamurockfestival.com

Set in Iwamuro, a hot spring area in Niigata Prefecture, this music event invites everyone to share what they love and enjoy, and to express it freely. Aiming to share the joy of spending time in the countryside, we bring out each person’s unique color, freely paint the space called Iwamuro, and share that time together by creating the event as one. Why not shift from spending your days just going into town to shop and coming home tired, to a way of living where you create your own enjoyment right in the town you call home?

Schedule	Saturday–Sunday, September 20–21, 2025
place	96-1 Iwamuro Onsen, Nishikan-ku, Niigata-shi, Niigata Prefecture
