Actor Seto Koji (34) and actress/model Yamamoto Mizuki (31) have welcomed their first child.

On Instagram, Yamamoto wrote, "This is a personal matter, but I gave birth to my first child the other day. Both myself and baby are healthy and doing well. I am so grateful for the support from many people." She added, "Meeting someone so incredibly precious, I am spending every day full of bliss. Please watch over us warmly so that we can continue to have peaceful days."

Similarly, Seto commented, "My first child was born the other day. I was so moved that I cried. With this child, everyday is much more fun, and my life has become more abundant. No matter what happens from now on, we will support each other as family."

Seto and Yamamoto married in 2020, and they announced their pregnancy earlier this year. Congratulations to the new parents!
