Rockin’on Japan has announced the third edition of its Western music festival, Rockin’on Sonic 2027, which is scheduled to take place on January 9 and 10, 2027, at SGC Hall Ariake in Tokyo.

Producer Yoichiro Yamazaki stated that the festival is moving from a 20,000-capacity venue to a 5,000-capacity hall to “ensure financial sustainability following previous losses.” The selected venue, SGC Hall Ariake, utilizes permanent immersive audio technology. 

The announced lineup for January 9 includes Bloc Party, Dinosaur Jr., Kim Gordon, and Violet Grohl, while the January 10 lineup features Suede, Pale Waves, Kula Shaker, and Dove Ellis. General ticket sales are scheduled to begin on October 10, 2026.
