City that's an anagram of "Tokyo" (5)
I believe the answer is:
kyoto
'city that's an anagram of tokyo' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for kyoto that I've seen before include "Japan's old capital" , "Japanese city of treaty on climate change" , "City of agreement on global warming" , "nearby city" , "Tokyo (anag) - former capital of Japan" .)
