AKB48’s Mayu Watanabe (20) was absent from Team B’s theater performance on October 27th due to poor health and Ayano Umeta (15) substituted in for her. An apology was issued to fans on the group’s official website, “We are deeply sorry for having to inform you all of this on the day of the performance.”

Watanabe’s condition is not deemed serious. Her agency commented, “She has been working continuously and it appears that she has suffered from fatigue. We will see how her condition is after tomorrow and decide how to act from there.”
