Japanese food (5)
I believe the answer is:
sushi
'japanese food' is the definition.
(sushi is a type of Japanese food)
This is all the clue.
(Other definitions for sushi that I've seen before include "Exotic food" , "Japanese cold rice dish" , "fare from Japan" , "'Dish of rice, vegetables and raw fish (5)'" , "Cold rice balls with raw fish" .)
