This is an antique Japanese military sake cup, decorated with a star, a chrysanthemum, and the words "Glory of the Nation". The smaller words on top are "Korea National Territory Defense Unit" and underneath "Discharge Commemoration". The soldier's name Nakahayashi is on the back. This is probably pre-annexation Korea as later cups tend to just mention Korea defense with a regimental number, instead of this "National Territory Defense Unit".
