Antique Japanese Military Battleship Column Profile Navy Sake Cup
This is an antique Japanese military sake cup, decorated with a picture of a battleship steaming and, I just noticed this, there's another ship in the smoke (you can see the top of the bridge of the 2nd ship). There's also a flag and anchor. The words are "Navy Term Fulfillment Commemoration" and the sailor's name Shitaakutsu.
