August Music Festivals [2026]: A roundup of summer festivals, outdoor rock fests, and other music events

A flagship Japanese music festival that has been held since 2000. It features many renowned artists from both Japan and overseas and is an event that draws attention from around the world. A distinctive feature of Summer Sonic is that it’s an urban, touring-style festival. In addition to easy access, the lineups for the Tokyo and Osaka venues swap over the two days. So whichever venue you attend, if you go both days, you can see all the headliners.

WILD BUNCH FEST. began in 2013 as the successor to SET STOCK, a music festival held in Hiroshima for ten years starting in 1999. One especially striking feature of WILD BUNCH is the small stage called “On the Sea,” which floats on the water in a small cove-like area within the venue and is used only for the closing act. Since it’s the closing act, the surroundings are fully dark by then, making the live performance on the tiny stage floating on the sea a must-see. Also, last year a campsite was set up inside the venue, allowing attendees to stay overnight from day one to day two, which is another highlight.

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.

RUSH BALL is a summer tradition of Osaka’s rock scene that has been held since 1999. The venue, Izumiotsu Phoenix, faces the sea, where you can feel the ocean breeze, and its sprawling lawns make for an incredibly comfortable festival experience. The lineup never disappoints—expect everything from staple festival veterans to promising young newcomers!
