September Music Festivals [2025–2026]: A roundup of autumn festivals, outdoor rock fests, and other music events

It’s a music festival organized by BMSG, the music agency led by artist SKY-HI. All the artists from the label who have been in the spotlight since the audition days will gather, making it an irresistible event for fans who have supported them from the beginning. Because the performers are labelmates who know each other well, you can expect an exciting clash of passionate performances as they try to take the event to the next level. SKY-HI himself will also take the stage, so it’ll be interesting to see what kind of sessions unfold.

This is a festival held with the spirit of energizing our town ourselves. Through the allure of music and the distinctive message of reggae, we will boldly share “what truly matters now” with like-minded friends. The festival also supports earthquake disaster recovery and provides assistance to children’s care facilities.

Slow LIVE, a self-styled “mini festival for grown-ups” held annually in Tokyo, is coming to Kanazawa. With reserved seating that lets you enjoy the artists at a relaxed pace, it’s the perfect break for those who are usually busy with work. Spend a long autumn evening in Kanazawa this year. From Kansai, take the Thunderbird; from the Kanto region, the Hokuriku Shinkansen—both will get you to Kanazawa in no time.

FUJIMAKI. This is a festival hosted by Ryota Fujimaki, the guitarist and vocalist of Remioromen. Hailing from Yamanashi, Ryota Fujimaki has poured his wish into this event to stir up a new breeze from Mount Fuji through music.

It was started by an organizer who has lived in Matsumoto for many years and wanted to make the city he loves even better through music. Matsumoto hosts events like the classical Saito Kinen Festival and the summer festival Matsumoto Bonbon, but because there weren’t any events centered on youth-oriented popular music, the Ringo Music Festival focuses on popular music—including J-pop, as well as rock and hip-hop.
