This is an antique Japanese military sake cup, decorated with a hand painted picture of a fortress heavy cannon. The words are "Yura fortress artillery soldier" "Victorious Return Commemoration". The soldier's name Ishida is on the back. It's not clear what war this was for, since the Yura fortress was in existence from the 1880s all the way to WW2.
