List of Artist-Hosted Festivals Nationwide [2026]

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.

There are music festivals all over Japan, but this time we’ve gathered artist-organized festivals from across the country.

Because these festivals are hosted by the artists themselves, you can feel the bonds and connections between artists, as well as their passion for the festivals.

You can enjoy a different atmosphere from ordinary festivals.
