Japanese government–issued dollar in Malaya and Borneo
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 to informally (and with contempt and derision) as banana money (Malay: duit pisang), named as such because of the motifs of banana trees on 10 dollar banknotes.
