American of Japanese descent (5)
I believe the answer is:
nisei
'american of japanese descent' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for nisei that I've seen before include "One born in the USA of parents who emigrated from Japan" , "American born of Japanese immigrant parents" , "Japanese Canadian/American" , "Second-generation American" , "that's evil? The reverse" .)
