Rock Festival Calendar for September [2025]

A lot of the up-and-coming artists everyone’s talking about will be performing. You can catch a wide range of acts all at once—from fresh faces lighting up the band scene to singers shaking up the acoustic world. Why not make it a memory to close out the summer?

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.

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!

Save The Birthday is a charity festival held every year in Hikone City, Shiga Prefecture. Because it’s a charity event, admission and parking are free, making it easy to attend. However, there are donation activities at the venue, so it would be great if you could donate in proportion to how much you enjoyed the event and use the energy you received from the music to help others.

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.

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.
