For those who have messaged me, a few more points I forgot to point out.
How successful you are, are depended on how you present yourself at the bouncer and how much you have done your research (some establishments have website with how to play SYSTEM, on the page, make sure that you have properly read and understand them.
Most establishments refused foreigners because they do not follow their SYSTEM and due to language issues, when unpleasant things happened, it gets really unpleasant. Which is why most of them been refusing Mainlanders in Tokyo.
For those who are going to try their luck in Tokyo, good luck
just avoid that specific place I told you guys (whoever messaged me).
