Music Festival Master / Editor-in-ChiefHane Keisuke
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.

Among the music festivals held in May, we’ve gathered events featuring rock bands.

From major annual rock festivals to rock fests where you can enjoy camping, and with the perfect weather there are plenty of circuit-style festivals as well.

Find the rock festival that suits you perfectly.
