Tamiko is introduced as Hajime Masuda's daughter, and it's said she's the same age as Adam Noshimuri, so she's about forty years old at that point, give or take a couple of years. The problem is that while she does look her age, her father looks like somebody in his late forties, maybe early fifties, but certainly not anywhere between sixty and eighty, as would be expected, which makes the whole father-daughter relationship very unbelievable.
