100 Rupiah Djepang (Japanese Rupiah)

This note belongs to a chaotic and poorly documented category of Indonesian revolutionary-era issues — local emergency currency printed by regional government bodies during the struggle for independence. Palembang, the main city of South Sumatra, operated with considerable administrative autonomy during this period, and the Kas Negara Daerah functioned as a regional treasury rather than a central banking authority.

The "Djepang" designation is the telling detail. It identifies the denomination in terms of the Japanese occupation currency still in common use as a reference point, even two years after Japan's surrender — a measure of how thoroughly wartime money had displaced Dutch colonial guilders in everyday trade.
