Varnish from the Far East (5)
I believe the answer is:
japan

(thesaurus)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for japan that I've seen before include "Land of the Rising Sun" , "Nippon" , "East Asian island nation" , "Glossy, black varnish; country" , "East Asian country" .)
