Relation moving from Japan? (8)
I believe the answer is:
oriental
'from japan?' is the definition.
(the Orient is the east)
'relation moving' is the wordplay.
'moving' is an anagram indicator.
'relation' is an anagram of 'ORIENTAL'.
(Other definitions for oriental that I've seen before include "Relation? (anagram)" , "Genghis Khan, say" , "from the East End?" , "Non-European" , "could be Chinese" .)
