The Japanese government-issued dollar was a form of currency issued for use within the Imperial Japan-occupied territories of Singapore, Malaya, North Borneo, Sarawak and Brunei between 1942 and 1945. The currency was also referred informally (and with more than a trace of contempt) as banana money (Malay: duit pisang), named as such because of the motifs of banana trees on 10 dollar banknotes. The Japanese dollar was in widespread use within the occupied territories where the previous currency became a scarcity. The currency were referred to as "dollars" and "cents" like its predecessors, the Straits dollar, Malayan dollar, Sarawak dollar and British North Borneo dollar.
