Best part of Japanese literature (5)
I believe the answer is:
elite
'best part' is the definition.
(I've seen this in another clue)
'of japanese literature' is the wordplay.
'of' indicates the answer is hidden within the clue.
'ELITE' is hidden within 'japanese literature'.
(Other definitions for elite that I've seen before include "Group considered to have superior status" , "Creme de la creme" , "Top group f" , "top drawer?" , "Upper crust" .)
