Tokyo Nightlife Information
In Japan, there is no tipping culture so tipping at restaurants is not needed. However, in prostitutes, even Japanese customers tip the girls! Tipping the girls shows that you enjoyed their service, and makes the girls happy. Tips between 1000〜5000 yen are good pricing. Why not give some tips to the girl if you are happy with her service?
