5 pesos Philippine peso

Japanese Occupation currency for the Philippines, Series issued 1942–1945 during World War II following the Japanese invasion and occupation of the Philippine Islands. These invasion notes, often called 'Mickey Mouse money' by Filipinos due to their rapid devaluation and poor quality, were printed by the Japanese Military Administration to replace the Commonwealth peso. The bilingual inscription 'THE JAPANESE GOVERNMENT' (English) and Japanese characters reflected Japanese military authority. These notes became nearly worthless by 1944 due to hyperinflation caused by massive overprinting to fund the occupation. All Japanese occupation currency was demonetized when the Philippines was liberated by Allied forces in 1945. The note's condition and heavy circulation wear are typical of these wartime emergency issues. The reversal of denominations (front shows '1 PESO' while back shows 'FIVE PESOS') suggests this may be a mismatched pair, though some sources document multi-denomination overprints during the chaotic final months of occupation.
