What Happened — The Full Story

On March 26, JYP Entertainment released a statement explaining that while preparing to depart with the other TWICE members, Chaeyoung suddenly experienced discomfort in her lower back. As she requires prompt medical attention, her departure was postponed and she remained in Korea to undergo medical examination and receive necessary treatment.

JYP added that her departure schedule will be decided based on the examination results and her recovery progress, and that they will aim for her to depart as soon as possible. They also cautioned that even if Chaeyoung does participate in the upcoming performances, her stage performance may be partially limited.

It’s the kind of sudden health update that hits fans hard — especially because it came with no warning and right before a departure day.

A Tough Time for TWICE’s Tour

This news comes on the heels of fellow member Dahyun’s ongoing ankle injury absence from the same THIS IS FOR world tour. TWICE — one of the most decorated and enduring K-pop girl groups of all time — is currently in the middle of Part 2 of their global tour, and having two members dealing with health issues simultaneously is genuinely difficult for both the group and their devoted ONCE fanbase.

That said, the members and JYP have consistently prioritised health over performance — and that’s exactly the right call. Stage performances put enormous physical strain on artists, and lower back injuries in particular can escalate quickly if not treated with care.
