Japanese military yen
The territories controlled or occupied by Japan had many different currencies. Taiwan maintained its own banking system and bank notes after it came under Japanese sovereignty in 1895. The same is true for Korea post 1910. Between 1931 and 1945, large parts of China and South East Asia were occupied by Japan. Several types of currencies were put into circulation there during the occupation. In China, several puppet governments were created (e.g. Manchukuo), each issuing their own currency. In South East Asia, the Japanese military arranged for bank notes to be issued, denominated in the various currencies (rupees, pesos, dollars, etc.) that had been circulating there prior to the occupation. These latter are referred to as Japanese invasion money. In addition to these currencies, the Japanese military issued their own bank notes, denominated in yen - this is the Japanese military yen. The military yen became the official currency in some occupied areas, e.g. Hong Kong.
