1000 Roepiah Japanese Occupation

The Japanese military currency issued for the Dutch East Indies during the occupation ran through several series, but by 1945 the infrastructure supporting meaningful monetary policy had largely collapsed. This 1000 Roepiah note was printed in Tokyo as the war situation deteriorated, and it was never intended to function as a stable store of value — Japanese occupation currency in the Indies suffered hyperinflationary pressure almost from the moment of issue, compounded by deliberate overprinting to fund military operations without drawing on home reserves.

After the August 1945 surrender, the Dutch attempted to suppress continued use of Japanese occupation issues, but Sukarno's republican forces actively circulated them during the independence struggle, briefly giving these notes a second political life they were never designed for.
