There have been several conflicts between Indonesia and Japan throughout history, but the most significant one is the period of Japanese occupation of Indonesia during World War II.

In 1942, Japan launched a surprise attack on Indonesia, which was then a Dutch colony, and quickly overran the country. The Japanese occupation of Indonesia was brutal and oppressive, and it lasted for three and a half years.

During this time, the Japanese military forced the Indonesian people to work as laborers and soldiers, and they committed numerous atrocities against the civilian population. They also banned the use of the Dutch language and culture, and they imposed their own language and customs on the Indonesian people.

The Japanese occupation of Indonesia came to an end in 1945, when the Japanese surrendered to the Allied forces.
