Typically, Japanese prostitutes are only allowed to pay in cash, but no worries! There is a way to withdraw cash!
If you own a credit card (VISA, Master Card, Union Pay, JCB, etc.), you will be able to withdraw cash from Japanese ATM!
Interests may vary depending on your card, but 7-Eleven ATMs (approx. 26,000 around Japan), Japan Post Bank ATMs, and Aeon ATMs usually allow the transaction!
Why not prepare some cash ready to have fun with Japanese girls!?
