This is an antique Japanese military sake cup, decorated with the big character "Imperial Award" in the center. The words on the back are "Taisho 8th Year May 7th Crown Prince Hirohito Adult Ceremony Commemoration" and the words in the base "Air Corps". Japanese have a "becoming adult" ceremony that now usually takes place when someone gets to 20. Hirohito became an adult when he was 18. This would've been given to someone who participated in the actual ceremony, thus the imperially gifted cup.
