Nice! I hope you review some of these someday, especially the BJ ones. I've only been to one pink salon in Osaka and it was pretty great. It was also a bit unusual because you had to get almost totally nude but the girl was quite young and went right down to the base with her mouth which was very impressive.
I will once my vacation is over. Right now I'm too busy sucking young Japanese titties every night lmaao.
For anyone wondering why I said being Asian from those countries helps is because all of the girls I've talked to said that the most common foreigners they had ever served was from those countries and those guys spoke little to no English (just like me apparently). Also, I've once spent 100k yen in a single club trying out all of their girls' titties (10-15 girls I think) and not one mentioned they have had US or EU customers. That's where I draw my conclusions.
My first words to them when entering their club or bars is always "English ok?" and wait for their reaction. If they goes like hmm/umm/erhh or" Japanese only", I'd reply "Google translator" follow by the following words translated to Japanese: "I've been to these type of clubs before and I understand the rules". Some establishments will asks what club, so just show them your "access pass". If your "access pass" is from a club advertised in one of those "information centres", your chances is very high. Also, the more cards you have from a single club the better, it shows you're a big spender and this will definitely ease things up.
As for identifying club managers owning a shop, your eyes needs to be sharp and have a high intuition. I saw a man wearing blazers making trips to a sheesha place and I call it. Went it, ordered sheesha, chill, talk to the staffs and confirmed that the owner indeed runs a titty bar. Young guys today likes Japanese rap and reggae, pretend you're into that shit and want to explore the genre. Build your friendship bonds and slowly creep into the topic of girls. Hehehe good luck.
Though your experience may be different from mine because I used a lot of mind games and psychological deceptions. Even managed to make 1 girl I met from a titty bar to frequent my hotel for the entire duration of my stay back in Tokyo
