I dont know about the skin colour thing. White is obsessed over but I dont think its that big of a deal for men. Okinawans are just as brown as Bimarus and a lot of men even like to get tanned. There's a lot of niggers around Shibuya and Kabukicho (they're pimps, drug dealers or Yakuza). Most people are afraid of niggers in general and don't go near them, they have the hardest time getting girls. I've noticed in a lot of Hentai black guys are talked about like wild animals and getting fucked by them is compared to bestiality.
