Music Festival Master / Editor-in-ChiefKeisuke Hane
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.

During the summer vacation from July to August, we’ve compiled a list of music festivals—such as summer festivals and rock festivals—held in western Japan (Tokai, Kansai, Chugoku, Shikoku, Kyushu, and Okinawa).

Check out the summer festivals that catch your eye and make this year’s summer vacation 100 times more fun!
