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.

We’ve put together an overview of fall festivals taking place across eastern Japan, from Hokkaido to the Hokuriku and Koshinetsu regions.

If summer festivals didn’t satisfy your appetite for fun, you’re not alone.

Check this out and keep enjoying the festival season!
