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.

There are all kinds of spring music festivals, and haven’t you ever regretted finding out about them only after they’ve ended?

1000-person ROCK FES. GUNMASaturday, 5/30, Gunma Prefecture

1000-rock.com

The 1000-Person ROCK FES held in Gunma Prefecture is a participatory rock festival! It’s an event where they recruit people to perform together on the day and have a session with 1,000 participants. The sense of freedom of playing outdoors with such a large group must be truly special. It’s the kind of fun event that seems obvious but is surprisingly rare! Each year, set pieces are announced, and anyone who applies can join the performance, so if you’ve ever wanted to play music with a big crowd, be sure to sign up!
