KATSEYE, scheduled to perform at SUMMER SONIC 2025 Tokyo on Sunday, August 17,
has decided to cancel the performance due to member Manon's poor health, and will perform with five members today.

The following is an announcement from the artist's management.

This is your KATSEYE community manager.

We are very sorry to share that Manon will not be able to perform at SUMMER SONIC TOKYO on Sunday, August 17, as her condition has declined upon landing in Tokyo. She has since made the decision after consulting her doctor to rest in order to recover as soon as possible. We know many EYEKONS were looking forward to seeing all KATSEYE members on stage at SUMMER SONIC TOKYO and we sincerely apologize for the unforeseen change.
Your health and safety, as well as that of KATSEYE members, is always our top priority, and we appreciate your understanding. We wish Manon a speedy recovery.
Thank you for your continued support for KATSEYE.
