Female Idol And Male Idol Announce The Birth Of Their First Child

An idol-idol couple is welcoming a new member into their family a year after saying, “I do.”

On March 12 of 2024, AAA‘s Uno Misako married Koyama Keiichiro, a member of NEWS. AAA (Attack All Around) is a co-ed Japanese group that debuted in 2005 under Avex Trax, while NEWS (North East West South) is a J-Pop boy group that debuted two years earlier under Johnny’s Entertainment.

On June 6, Misako announced the birth of her and Keiichiro’s child in a heartwarming post on X (formerly Twitter).

The other day, I safely welcomed our first child into the world. I can’t thank my family, friends, staff, doctors, and nurses enough for their unwavering support—and to our fans for the lovely messages that truly lifted my spirits.
The instant I held our little one, I felt an overwhelming surge of love. In that moment, I realized there’s now someone more precious than my own life. Moving forward as a mother, I want to pour every ounce of love into keeping this tiny miracle safe, healthy, and happy—every single day, every single second.
Once I’m properly recovered—both in mind and body—I’m determined to return to the stage and give my all to my music. I hope you’ll keep cheering me on as I balance motherhood with my passion for singing.
