Japanese entertainer (6)
I believe the answer is:
geisha
'japanese entertainer' is the definition.
(geishas traditionally hosted or entertained men)
This is the entire clue.
(Other definitions for geisha that I've seen before include "Trained Japanese hostess - his age (anag)" , "Japanese paid companion" , "He's a GI (anag.)" , "Hostess in a kimono" , "Jap. entertainer" .)
