LE SSERAFIM wraps Summer Sonic 2026 with 14-song live-band set, Japan tour 'PUREFLOW' continues

LE SSERAFIM took two Summer Sonic 2026 stages. Osaka Expo Commemoration Park on August 14. Chiba Zozo Marine Stadium on August 16. Both nights brought a 14-song set, roughly an hour long, backed by a live band.

They opened with CELEBRATION and Creatures from their second album, moved through HOT, Perfect Night, 1-800-hot-n-fun, Saki, Irony, and BOOMPALA. The closer was catalog heavy: CRAZY, SPAGHETTI, ANTIFRAGILE. Pentatonix's official account called them "an iconic group" after the shows.

Sakura posted on Instagram August 20—mic in hand, standing in front of an outdoor structure under summer sky. "Thank you Summer Sonic."

These dates sit inside the 2026 LE SSERAFIM TOUR 'PUREFLOW' IN JAPAN, which has already taken Kim Chaewon, Sakura, Huh Yunjin, Kazuha, and Hong Eunchae through Osaka, Kanagawa, and Shizuoka. Miyagi and Fukuoka still ahead.

Next stop: the US. A closing set at BlizzCon 2026 (roughly one hour) and a slot at the 2026 iHeartRadio Music Festival. They'll be the first K-pop girl group to perform on that stage.

(As of 5 PM KST on August 20, LE SSERAFIM sat at 17th place in the Best Group category of the August Netzien Awards with 17 votes.)
