This is an antique Japanese military sake cup, decorated with an anchor, a flag, and a shell in the center, with a crane on top. Usually the object in the cup has something to do with the sailor's job on the ship - a propeller means someone who worked in the engine room, and in this case a shell is probably someone who worked with the guns. The words are "Navy Term Fulfillment Commemoration". The sailor's name Furuyama is on the back.

Condition: Excellent - slight fading around the rim
