Cooperation with the Japanese

Sukarno was willing to support the Japanese, in exchange for a platform for himself to spread nationalist ideas to the mass population. The Japanese, on the other hand, needed Indonesia's workforce and natural resources to help its war effort. The Japanese recruited millions of people, mainly from Java, to be forced labour called romusha in Japanese. They were forced to build railways, airfields, and other facilities for the Japanese within Indonesia and as far away as Burma. Additionally, the Japanese requisitioned rice and other food produced by Indonesian peasants to supply their troops, while forcing the peasantry to cultivate castor oil plants to be used as aviation fuel and lubricants.
