The Japanese occupation of Malaysia during the Second World War has occupied a significant space in national history textbooks in Malaysia. The period has been associated with nationalist movements and independence from colonial rule. However, narratives of the Japanese occupation in school history textbooks have changed in terms of the importance given to the experiences of the three major ethnic groups in Malaysia (the Malay, Chinese, and Indian ethnic groups). This article presents an analysis of the Japanese occupation as portrayed in Malaysian national history textbooks from 1978 to 2020. It demonstrates a link between ideology and the state curriculum in Malaysia, which shows how cultural and ideological factors (namely, the political ideology of Malay dominance, or ketuanan Melayu) explain the changes made to the narratives in history textbooks.
