5 Gulden Japanese Occupation

Issued under the Japanese Military Administration following the occupation of the Dutch East Indies in early 1942, this note was part of a broader currency program designed to displace Dutch colonial guilders and fund the occupation without drawing on Japan's own reserves. The series was nicknamed "Mickey Mouse money" by locals across occupied Southeast Asia — a term applied broadly to Japanese military scrip, reflecting the population's accurate assessment of its long-term value.

Redeemability was never guaranteed. After Japan's surrender in August 1945, the notes were declared worthless by the returning Dutch authorities, and enormous quantities were simply abandoned or destroyed. Surviving circulated examples from Indonesian archipelago use often show tropical humidity damage to the paper.
