Tokio's Yamaguchi Tatsuya has become a father for the second time to a second son on the 17th of this month. He even worked his schedule so he could be present for the birth.
His first son was born about two years ago shortly after his marriage to his wife.
I have to say that it was rather sweet of him to make sure he could be there for the delivery. And his sons probably have some of the best 'uncles'.
