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 a list of music festivals in Okayama Prefecture, including summer festivals, rock festivals, and outdoor festivals.

This year as well, we look forward to welcoming you to captivating events such as “Hana Fes,” “Hoshioto,” and “Kurashiki Jazz Street!”

HOTARU Fes is a music festival held in Hokubo, Maniwa City—home to the world’s most fireflies. Organized by local music and event enthusiasts, it takes place every June when the fireflies dance. Musicians from a variety of genres, as well as food vendors, workshops, and art from in and outside Okayama Prefecture, gather with Maniwa at the center, creating a festival that people of all ages—from small children to adults—can enjoy all day. You can let loose to live music, enjoy delicious meals and sweets, and take part in workshops or get a portrait drawn. After enjoying HOTARU Fes, be moved by the breathtaking display of Hokubo’s world-leading firefly swarms.
