Acclimatise in Japan maybe (6)
I believe the answer is:
orient
I believe this is a double definition.
'acclimatise' is the first definition.
(I've seen this in another clue)
'in japan maybe' is the second definition.
(Japan is part of East Asia ie the Orient)
(Other definitions for orient that I've seen before include "Align (in a particular direction)" , "Establish one's position" , "Align (relative to a specific direction)" , "Adjust to surroundings" , "Acquaint with position" .)
