For the most part, guys hitting on girls isn’t really a part of Japanese culture. Thankfully, there are a number of social institutions that take its place, such as frequent student mixers, company drinking parties, and singles’ dinners organized by groups of friends with an exactly equal number of unattached men and women present.
All of this largely circumvents the need for a guy to go up to a girl that catches his eye in a book store or coffee shop with nothing more than a smile and a hello. It also means that if a man is out and about and spots an attractive woman, if there’s no one to give him a formal introduction, a glance at her pretty face, and maybe a moment where her eyes meet his, is about all that he can ever hope to take away from the encounter.
For some guys, though, that’s enough, and for them, there’s a new website featuring nothing but short videos of cute girls walking past you.
