What is Japanese Invasion Money?

Japanese Invasion Money (JIM) is the currency that was issued by Japan to replace local currencies of areas they had occupied, defeated or had plans to, in World War II. JIM was officially known as Southern Development Bank Notes. 

The main purpose of introducing the new currencies was to cripple the economies of these areas as with the introduction of JIM their own currency was rendered worthless. Japanese troops strongly enforced the use of their new ‘mickey mouse’ or ‘banana’ money and harsh penalties, including death, were applied for people caught using non-JIM currency.

Japan’s prime minister of the time, Matsuoka Yosuke and the Government had a vision of a united Asian power lead by Japan. This was to be known as the Greater East Asia Co-Prosperity Sphere. This concept, similar in theory to today’s European Union, would be independent of the West and be a force lead by Japan for the greater prosperity of Asians. Although Japan was promoting prosperity for all Asians, they still had a distinct ‘pecking order’ with the nation’s allies.

By the end of World War II, invasion monies were issued for: Philippines; Burma (Myanmar); Malaya (Malaysia, Singapore); the Dutch East Indies/Netherland Indies (Indonesia) and Oceania (British New Guinea, the Solomon Islands , the Gilbert Islands and Australia).

Throughout WWII, JIM notes became souvenirs of returning soldiers who brought back captured notes to Australia and used these as proof of the intended invasion of Australia by Japanese forces.

For the avid collector, JIM notes are an ideal item to make into a collection. You may start with just collecting the notes that relate to your chosen country or you can complete a standard set collection with a note to represent each denomination and region. For the more-serious collector, you can add to this examples of prefixes, variations, propaganda notes, flyers and coins.
