This is an antique Japanese army sake cup, decorated with a helmet with two flags, one of which is the flag of Manchukuo. The words on the cup are "Victorious Return Commemoration" and "Manchuria Aoki Unit". Unfortunately when units are named by their commander (instead of using the unit number) it's almost impossible to know for sure what unit it is, but it's fairly uncommon to find units named with commander on cups as they normally use numbers. The soldier's name Morimoto is on the back.

Condition: Excellent - slight fading of the gold
