Novelbright guitarist Sojiro Oki has announced the birth of his first child, a baby girl.

Oki shared the news on social media on August 15, several months after announcing his marriage to freelance announcer Kayo Matsumoto and revealing that the couple was expecting their first child.

Sharing a glimpse into his first day as a father, Oki joked, "I was so bad at changing her diaper for the first time that she burst into tears. I'll do my best as a first-year dad!"
