The Indonesian-language version of a Japanese book depicting the little-known story of a Japanese man who fought for Indonesia's freedom will be published next month.

The book is "Zanryu Nihon-hei no Shinjitsu" ("The True Story of a Japanese Soldier Who Stayed Behind"), written by Eiichi Hayashi and published in 2007.

The book tells the true story of Sakari Ono, who fought alongside Indonesian independence troops against the Dutch colonial forces.
