Why does Yagami look older than his actor?

Yagami and Ichiban would've been fine replacements for Kiryu if Yagami didn't look like he sells meth to teenagers and Ichiban wasn't literally in the same age range as Kiryu.

I know one of the unique qualities of these games is the older than average protagonists but damn, isn't this just way too old for a series that's trying its hardest to move on to a new generation of characters?
