This paper aims to examine publications, which were read by the Indonesian people during the Japanese occupation (1942–1945) mainly in Java, Indonesia in relation to Japanese ruling policies for Java.

First, the publications in Catalogue of Publications during the Japanese Occupation, which was compiled and published by the Indonesian National Library in 1983, were classified into 4 categories based on publishers, i.e. Japanese Military High Command in Java and its bureaus, Balai Pustaka established by the Dutch Colonial Government, newspaper companies, and private publishers. Second, the publications of each category were further analysed by writer, language and method of dissemination.

It was revealed that all the publications were under suverillance of the Japanese army, but the Japanese army also had to change their policies in response to the culturally divided society. Furthermore, some publications in the fields of humanities including literature remind us of the necessity to explore why those publication were possible to come out during the Japanese occupation from various perspectives in the future.
