He wrote many columns and short articles criticizing the Indonesian government. He wrote a book "Perawan Remaja dalam Cengkeraman Militer" ("Young Virgins in the Military's Grip"), a documentary written showcasing the plight of Javanese women who were forced to become comfort women during the Japanese occupation and were subsequently subject to oppression by their own Indonesian society. The Japanese military took these women Buru island. They were raped and sexually abused by the Japanese. Many stayed there instead of returning to Java. Other political prisoners on Buru with Pramoedya were able to meet some of these women. They told the women's stories to Pramoedya. He wrote them down in narrative form in the 1970s. This was the start of the book published in 2001.
