Are the characters' real names realistic/common in their cultures?

As title says. I feel for the most part, the english-speaking country characters have pretty realistic names (Jack Morris, Gabriel Reyes, etc), but I was wondering for characters of other nationalities.

Speaking as a Japanese person, nobody would realistically name their kid Genji-- akin to naming your child MacBeth. Hanzo is an old man name, better fitting if he was born in the 1930's. Shimada is a plausible name though. Kiriko is a believable but definitely unique name that you'd probably never meet two of.

(edit- I remembered reaper's name wrong💀)
