Summer Music Festival Held in Eastern Japan [2026]

@JAM EXPO, which began in 2014, is an event that has continued to be held even as the idol scene undergoes various changes. With the goal of widely introducing Japanese culture and further energizing the idol scene, it is carried out with passionate dedication. Aiming to be the best idol festival in Japan, it’s a must-see event for idol fans.

As a new festival organized by Ibaraki Broadcasting, the LuckyFM Green Festival has been held since 2022. Following the relocation of the ROCK IN JAPAN FESTIVAL, the event has adopted the motto “Don’t let the flame of Ibaraki’s festival culture go out,” and has been reimagined with a new concept as a celebration of music, food, and art at its venue, Hitachi Seaside Park. Featuring local ingredients and a wide range of art and music genres, it’s also recommended as a family-friendly event. It’s sure to become one of your favorite summer memories!

Started in 1999 as Japan’s first full-fledged all-night outdoor rock festival, RSR is a large-scale open-air rock event that makes the most of Hokkaido’s vast landscape. A major feature is that you can pitch a tent and camp—chat with friends around your campsite, stay up all night catching live shows, or choose freely among the nearly simultaneous performances across multiple stages. How about crafting your own two days of freedom, in your own way?

Held since 2009 under the name KESEN ROCK, this event wasn’t started by band members or event promoters, but by ordinary people. It’s described as an event “made entirely by hand without even knowing what a rock festival is,” making it a celebration of true DIY spirit.
