50 Sen Japan Military Currency

Japanese military currency (gunpyo) issued from 1940 onward was designed to extract local resources and labor in occupied territories without drawing on Japan's domestic money supply. This 50 Sen note belongs to the series circulated across the expanding Co-Prosperity Sphere — accepted as legal tender in occupied areas but backed by nothing, deliberately severing the cost of occupation from the home economy.

After Japan's defeat in 1945, Allied authorities declared all military yen worthless, leaving enormous quantities unredeemed. Holders — many of them civilians in occupied territories paid in this currency — received nothing.
