On June 29, BIGMAMA's Mao Higashide announced that she married 9mm Parabellum Bullet's Yoshimitsu Taki last year and recently welcomed their first child.

In a statement, Higashide explained that she chose not to disclose her pregnancy when announcing her hiatus in September 2025 due to the risks associated with giving birth at age 43. She said she and her baby are both healthy and thanked her bandmates, staff, and fans for their support.

Higashide added that she hopes to return to activities once her health has recovered and after discussing the timing with her bandmates.

BIGMAMA said they will continue performing with guest and support members while preparing for the band's upcoming 20th anniversary.
