List of Rock Festivals in the Kanto Region [2026]

The 1000-Person ROCK FES held in Gunma Prefecture is a participatory rock festival! It’s an event where they recruit people to perform together on the day and have a session with 1,000 participants. The sense of freedom of playing outdoors with such a large group must be truly special. It’s the kind of fun event that seems obvious but is surprisingly rare! Each year, set pieces are announced, and anyone who applies can join the performance, so if you’ve ever wanted to play music with a big crowd, be sure to sign up!

DEAD POP FESTiVAL, which has been held since 2010 under the slogan “Break the Wall,” has firmly established itself as an outdoor event and joined the ranks of summer open-air festivals. The festival is hosted by the hugely popular reggae-punk band SiM. Because SiM is always taking on new challenges, the event has featured initiatives unlike anything seen before. This year as well, their fresh ideas will no doubt make it an incredibly fun experience.
