'capital' is the definition.
(I have seen 'Old capital' mean 'kyoto' so perhaps 'capital' could also mean 'kyoto')

Can you help me to learn more?

(Other definitions for kyoto that I've seen before include "Former Japanese capital city - Tokyo (anag)" , "Japanese city of treaty on climate change" , "City of agreement on global warming" , "Japanese capital before 1868" , "Old Japanese capital" .)

I've seen this clue in the Irish Times.
