List of Eastern Japan summer festivals held during the summer vacation [2026]: rock festivals and outdoor music festivals

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?

SWEET LOVE SHOWER is an outdoor festival organized by SPACE SHOWER TV. These days it’s held at Lake Yamanaka at the foot of Mount Fuji. With its location offering views of Mount Fuji and a lineup packed with popular artists, it’s an extremely popular event.

@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.
