God, PUAs are so fucking cringy. He probably thinks he's "peacocking". It's bad enough people fell for this shit in the 2000s, but doing this shit in 2018 makes you a legit retard.
No surprise he's getting rejected. He's a manlet with a receding hairline that dresses like he's trying to win a cringe contest.
On top of that, Japanese women are extremely picky. You think western women are picky? You ain't seen nothin. There's numerous studies that show the insanely high percent of men who are virgins and never had a girlfriend and how insanely high the standards of most Japanese women are. Not to mention, a lot of the women are completely disinterested in men altogether. A lot of Japanese men have completely given up on finding a girlfriend/wife and just spend their free time playing MMOs, watching anime, and cope with their dakimakuras and anime figures. There's a reason all that stuff comes from Japan. All of these problems are well documented and acknowledged by the Japanese government as they have led to an extremely low birth rate. The government has tried to provide financial incentives for people to get married and have children but so far it hasn't really worked.
Point being, obviously a sub5 foreigner is not going to have any luck with women in Japan.
That said, a decent looking blond haired blue eyed guy like @Weed or a pretty boy like @knajjd could probably get a girlfriend there.
