Editor-in-chief of RAG MUSIC and in charge of music festivals. When I attended my first music festival as a freshman in college, I was captivated by its charm—“I can’t believe there’s a place this free and this fun.” I share information about wonderful music festivals every day to help grow the community of festival fans.

From large-scale festivals to smaller ones, there are now countless exciting festivals being held.

Especially in summer, there are so many that it’s hard to keep up with all the information.

Here, we’ve compiled a list of summer music festivals taking place in eastern Japan.

SUMMER SONICAug 16 (Sat)–17 (Sun), Chiba Prefecture

A flagship Japanese festival that has been held since 2000. Not only top domestic acts but also many renowned international artists perform, making it an event that draws global attention. A defining feature of Summer Sonic is that it’s an urban, touring-style festival. In addition to being easily accessible, the Tokyo and Osaka lineups swap over the two days. So whichever venue you attend, if you go for both days, you can see all the headliners.
