1 Sen Japanese Military Occupation

The Japanese military scrip series issued from 1939 onward was designed explicitly for use in occupied territories, giving Japanese forces a parallel currency that could be kept separate from the domestic yen supply. The 1 Sen denomination is the lowest value in the military scrip sequence — practically worthless in purchasing power even at the time of issue, and largely a token instrument meant to facilitate small change transactions in occupied areas rather than serious commerce.

The Cabinet Printing Bureau produced this in Tokyo, well before Japan's wartime paper shortages began degrading print quality across later issues in the same series.
