List of Rock Festivals Nationwide [2025–2026]

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?

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.

Since 1977, this has been a long-running event. It takes place at Seagaia. It’s divided into Jazz Night and Juke Night: Jazz Night features seasoned veterans, while Juke Night brings together trending bands and artists, drawing a lively crowd of all ages.

Koyabu Sonic is hosted by Chihiro Koyabu, a hugely popular TV personality known for Yoshimoto Shinkigeki. The event will take place over three days using Halls 2 and 5 at Intex Osaka. In addition to performances by the Yoshimoto Shinkigekis band—formed by Yoshimoto comedians who are expanding their activities across the country—many comedian stages are also planned.
