This is an antique Japanese military sake cup, decorated with a big regimental color and cherry blossoms. The words on the back in the center are "18th Infantry Regiment 3rd Company". There are seven full names on the back of the cup as well, which is quite unusual. A Japanese army company had five officers plus a sergeant major and a number of corporals. I'm guessing this is probably a cup for one of the officers - and the seven names are probably most of the officers/NCOs who gave the cup.
