Dancing, she could entertain one visiting Ginza on vacation (6)

I believe the answer is:

geisha

I'm a little stuck... Click here to teach me more about this clue!

But I can't explain it at all! Could you help me understand?

(Other definitions for geisha that I've seen before include "Jap. hostess" , "Japanese serving girl" , "Japanese hostess who entertains men" , "Professional Japanese hostess and entertainer of men" , "One employed to look after men" .)

I've seen this clue in The Hindu.
