Antique Japanese MIlitary China Incident Ogawara Unit Army Sake Cup
This is an antique Japanese military sake cup, decorated with a star on the front. The words on the back are "China Incident Participation Commemoration" and "Ogawara Regiment Matsumaru Unit". Ogawara would've been the regimental commander, and Matsumaru was a subordinate - company captain, perhaps.
