[2025–2026] Complete Kanto Summer Festival Guide: Music and Outdoor Festival Information

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.

The outdoor festival season that colors the Kanto summer has arrived.

Under a wide-open blue sky, a special space woven by music and nature sets the stage for moving live performances.

From venues you can enjoy on a day trip from the city center to camp-in festivals where you can stay overnight, a wide variety of events are lined up to meet music fans’ expectations.

Powerful performances by top-tier artists from Japan and abroad, together with encounters with fresh new talent, will make your summer memories shine.
