One is from Tokyo, say (8)
I believe the answer is:
japanese
'one is from tokyo say' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for japanese that I've seen before include "One from Tokyo, say" , "Native of Nagasaki" , "This nationality apes Jean" , "Asian people" , "This nationality uses a Nasa jeep incorrectly" .)
