tokyo

I'm a little stuck... Click here to teach me more about this clue!

'capital' is the definition.
(capital of Japan)

I don't understand the rest of the clue.

(Other definitions for tokyo that I've seen before include "City once called Edo" , "Far Eastern capital" , "Large Japanese city" , "Asian capital" , "This covers an Asian city" .)

I've seen this clue in The Guardian.
