Complete Guide to Spring Festivals in the Kanto Region! Introducing Featured Artists and Venue Information [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.

Music festivals held across the Kanto region with the arrival of spring.

Enjoying live performances under the blue sky is a special experience that lets you truly feel the comfort of the season.

From large venues in the heart of the city to nature-rich locations in the suburbs, a variety of distinctive spring festivals captivate music fans.

Powerful stages by top artists from Japan and abroad, encounters with local gourmet food, and the liberating feeling of being wrapped in a pleasant breeze.

This spring, why not discover a music experience that’s uniquely yours?
