This is an antique Japanese military sake cup, decorated with a picture of the Himeji Castle, with the words "Himeji Castle" "Leaving the service commemoration" and "39 Infantry Regiment". Himeji served as the regimental HQ, which is why the castle is in the cup.

Condition: Excellent - the cup's rim is a bit rough to the touch but it's not chips

Size: 2" across
