Here is a great documentary on the art of “Nanpa”. Nanpa is seen most often in young heterosexual men ranging from their late teens to mid-twenties. Groups of “Nanpa boys” will gather around places with busy, predominantly female foot traffic (bridges, subway stations, shopping malls, etc.) and approach women in search of a date. The Nanpa groups generally wear high fashion with nice suits, expensive shoes, and extravagant hair styles. Because of their style of dress, Nanpa boys are occasionally misinterpreted by foreigners as employees of host clubs, who also roam such areas speaking with various women. If you are in Osaka near Shinsaibashi you will see this in droves.
