List of Rock Festivals in Western Japan [2025–2026]

This is an outdoor festival hosted by WANIMA, the popular three-piece rock band known for doing commercials and theme songs. Holding a festival they run themselves in their hometown of Kumamoto is a long-awaited event for both the band and their fans! I can’t wait to see which of their close-connected bands will be on the lineup. It’s a must-see event for fans who want to fully enjoy both music and Kumamoto. If you’re visiting Kumamoto for the first time, be sure to set aside plenty of time and go have fun!

TREASURE05X is held every summer. Speaking of summer, it’s all about the beach—and festivals! Since Laguna Beach hosts a seaside summer festival, it’s the perfect event to soak up the season to the fullest. With the crowd’s energy, you’ll forget the heat as you lose yourself in the music, and enjoying the local food and drinks is another highlight. The lineup is packed with hot artists, especially from the Japanese rock scene, making it tough to choose which date to attend. If possible, you’ll want to go to all of them.

RUSH BALL is a summer tradition of Osaka’s rock scene that has been held since 1999. The venue, Izumiotsu Phoenix, faces the sea, where you can feel the ocean breeze, and its sprawling lawns make for an incredibly comfortable festival experience. The lineup never disappoints—expect everything from staple festival veterans to promising young newcomers!

Sky Jamboree, a long-running rock festival held since 1999, is an outdoor festival that takes place every year in Nagasaki. With many popular rock bands on the lineup, it’s an event you’re guaranteed to enjoy if you attend.

ONE Music Camp is billed as “a festival where everyone plays together,” with a concept of enjoying music and playing freely amid great nature. The venue, Sanda Athletic, is a campsite in a natural setting featuring plenty of wooden athletic equipment, and as the festival’s name suggests, attendees can camp at the event. Even without a tent, you can stay in a bungalow, making it easy to enjoy camping. Be sure to experience the collaboration between nature and music.

MONSTER baSH is an outdoor rock festival that has been held in Kagawa Prefecture since 2000. It’s affectionately known by its nickname, “Monbasu.” Since 2003, the main venues have consisted of two stages: STAGE Kukai and STAGE Ryujin. These two stages are set up side by side, so you can see every act performing on the main stages. There’s also an area at the back of the main stage zone where you can lay down sheets or set up parasols, making it possible to stay comfortable even in the intense heat.
