There is a huge faction of people in this country that have no interest in talking to foreigners which are known as gaijin. If you are a tourist passing through or an expat you will notice that many places are not foreigner friendly.
As a gaijin you will literally not even be allowed inside. Asian culture can be a bit strange at times, so to keep their customer base happy, smiling, and spending they just exclude foreign men. Its alright though, this is a massive city and there are many slutty and sexy Tokyo girls who are interested in dating or hooking up with foreign men, and there are a ton of nightlife options.
This is where you can find much of the best nightlife in Tokyo, and where most gaijin go to party. The slutty and sexy Tokyo girls interested in foreign men will follow. Additionally, this just means that you know any girl in a gaijin friendly bar is there because she likes foreign men. Not saying it is better this way, but it helps you avoid walking up to some girl that speaks no English and has no interest in you.
There are so many options for places to go in the Roppongi nightlife to meet single ladies that it seems almost silly to mention any specific places. That said some gaijin friendly pick up bars in Roppongi are Jumanji , Color , and Greenland. When trying to pick up these hot Tokyo girls at singles bars or nightclubs be aggressive and try to strike up a conversation with any sexy girl that catches your eye.
She will make it clear whether she is interested or not pretty quickly. If you want some bigger clubs in the Roppongi nightlife with loud music and lots of dancing you can head to V2 , Muse , or Ivy. It should be noted there is very high turnover with these pick up bars and nightclubs in Roppongi. They change names often, but there is so much nightlife in the area you can always find something to do.
