Charan-Po-Rantan's Koharu has announced the birth of her second son! Named Teo birth to her second son on March 17, announcing that his name is Teo.

Koharu previously welcomed her first son Mito in January of 2025. In September, she revealed that Mito was born with severe cerebral palsy due to complications during delivery, which inspired her to release the song "Mito" in his honor.

Regarding her second child, Koharu shared, "When I heard his first cry, all the emotions from everything we’ve been through came flooding over us, and we cried together." She gave birth via planned C-section with her husband, Italy-based artist Kensuke Koike, by her side. She added, "Honestly, I’ve never really raised a newborn properly, so everything from milk amounts to routines, is new. I never imagined I’d have two children, but we’re grateful for all the support. We’re doing well." Her post also includes heart-warming photos of her holding Teo and Mito watching over his baby brother.

Koharu will resume her live activities on April 25 and 26 at the '18th Koenji Bikkuri Street Performance 2026' near JR Koenji Station in Tokyo. Her first comeback live with Charan-Po-Rantan will be on June 14 at Billboard Live Tokyo, titled 'Charan-Po-Rantan Sisters Theater 2026.'

Congratulations!
