My Japanese wife is in her 60’s but has been hit on ( when I wasn’t around ) by much younger Americans stationed here in Okinawa . No plastic surgery and no makeup !
The Japanese, in general, have good bone structure which causes them to look much younger than they are. I have to laugh at “50” which is just before you go off of an aging “cliff” right around 52. Particularly for women with meno setting in. I’m stb 66 F but my parents always looked MUCH younger than they actually were—genetics always plays a part. I think the next aging “cliff” is late 60s/early 70s.
