Tokyo Idol Festival 2026: rain‑forced cancellation prompts surprise live, while major groups perform

On August 1, the outdoor SKY STAGE at Tokyo Idol Festival 2026 was shut down after a thunderstorm. The idol group 衛星とカラテア (Eisei to Karate) had been scheduled to close the stage, but the organizers moved the act to the indoor venue EBiS303, where the group performed the full setlist for fans who had waited in the rain.

The festival’s final day, August 2, featured a series of headline performances. IS:SUE made its debut on the main stage, delivering a 30‑minute set of seven songs from their album QUARTET, including a brand‑new track “Chemistry.” NMB48 energized the crowd with a summer‑themed setlist and celebrated member 新澤菜央’s birthday. HKT48 marked its 15‑year anniversary with a 30‑minute medley of classic and recent songs. Other groups such as 超ときめき♡宣伝部 also performed on the opening day, highlighting the festival’s diverse idol lineup.
