Gloss over the country (5)

I believe the answer is:

japan

I believe this clue is a double definition.

'gloss' is the first definition.
(I have seen 'black gloss' mean 'japan' so perhaps 'gloss' could also mean 'japan')

'the country' is the second definition.
(Japan is an example)

'over' acts as a link.

(Other definitions for japan that I've seen before include "black gloss" , "Country in East Asia" , "Glossy black lacquer" , "East Asian country" , "Glossy coating" .)

I've seen this clue in The Globe and Mail.
