This is an antique Japanese military sake cup, decorated with a naval insignia in the center and the word "Award" on top. The words on the back are "Showa 10th Year Maizuru Defense Unit" "Carrier Pigeon Skills Competition". Anything related to pigeon carriers are extremely rare - as they were small units with highly specialized uses. The Japanese navy maintained carrier pigeons for ship based use, which was apparently fairly reliable.
