This is a pretty interesting Japanese military sake cup, decorated with two branches of cherry blossoms and the words "War Commemoration". On the exterior are the words "Meiji 37/38th Years War Commemoration", which refers to the Russo Japanese War, and "Ro Ship Docks Headquarters". After doing some research it seems to be a name for a group of ship dockings near present-day Incheon, which was a major port already at the time. Some Japanese warships, for example, sailed to Incheon during the war for refit and supply after the Battle of Yellow Sea. The cup comes with original wooden box and under the lid of the box is a stamp from a lacquerware shop based in Hiroshima, which would suggest a navy connection - Hiroshima is next to Kure, the main naval base for the Japanese navy.
