Tokyo's country (5)
I believe the answer is:
japan
'tokyo's country' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for japan that I've seen before include "Far Eastern island country" , "Country and decorated black lacquerware" , "black gloss" , "East Asian island nation" , "It's a string of more than 3,000 islands" .)
