You can never be too prepared.
Here are the five most important tips you should keep in mind before going out for a night club.
(1) ID

Do not forget your ID with face photo (Passport is fine). You are always asked to show your ID to enter a nightclub at the security entrance.
(2) Not wear shorts and sandals

Do not wear short pants and sandals. You are required to wear long shorts and you would be stopped at the entrance if you put on shorts and sandals.
(3) Not get drunk too much until you get inside

Avoid getteing you drunk too much before getting inside of a night club. If security could recognize you drunk too bad, you will be ousted.
(4) Wear collar shirt

Always much better than wearing T shirt. This is not mandatory but wearing shirt make you nicer.
(5) Bring Cash

Do not forget to bring cash of around 10,000 yen (if you drink inside and treat some girls).
Usually you need 3,000 – 3,500 yen for entry and some clubs only accept cash for payment inside.
