This is a rare antique Japanese military sake cup, decorated with a field gun, a pair of cherry blossoms, and the words "Great East Asian War Commemoration". The soldier's name Kaneko is on the back, with an embossed decoration on the outside. Great East Asian War was named after Pearl Harbor, meaning this cup is definitely from 1941 or later. Those cups are overwhelmingly non-unit specific - so seeing an artillery themed one is quite rare.
