BABYMONSTER - SUMMER SONIC 2026 & WORLD TOUR [춤 (CHOOM)] BEHIND in JAPAN #2

Why Koreans care

BABYMONSTER is YG Entertainment's marquee new act since BLACKPINK, so landing three SUMMER SONIC invitations in a single year and moving up to the main stage reads in the Korean industry as a signal that YG is fast-tracking this group's status in the Japanese market specifically. Two of the members featured, ASA and RUKA, are Japanese, and building a Korean idol group with members from a key overseas market is a well-worn K-pop strategy for deepening that market's emotional investment — which is also why this Japan-focused footage leans harder into fan-facing warmth than a typical tour-stop video.

What the words mean

During rehearsal, one member waves off a difficult high note with "I give up... my voice will just figure itself out," which reads to an outsider like an unprepared performer shrugging off a hard part days before a major festival set. Inside Korean idol reality content this is a stock practice-room bit — a joking bet on stage adrenaline over rehearsal polish — and Korean viewers clock it as normal banter rather than a red flag about the show's quality.
