This is an antique Japanese military sake cup, decorated with a pair of flags and the words "13th Infantry" and the soldier's name Nagata. The odd thing about this cup is that one of the flags is missing decoration - this might be a good example of how cups were painted - they would fill one of the flags with stuff when ordered. It's quite odd and unusual that this one is left blank for some reason.
