After the end of the war , Daigo was arrested by SCAP authorities at the request of the Netherlands government , and was extradited to Batavia in the Dutch East Indies , where he was charged with war crimes in connection with the kidnapping , torture and massacre of 21,000 people ( including women and children ) by Japanese troops in Pontianak during the Pontianak incidents . After being held for several months under severe conditions , he was found guilty in a closed military tribunal at Pontianak after only three hours of testimony , during which time he was not allowed to speak in his own defense , and was executed with a rifle shot to the stomach on 6 December 1947 . As Daigo was commander of submarine forces , ( although from 8 November 1943 the 22nd Special Guard Division based at Balikpapan , Borneo fell nominally under his command ) , his connection ( if any ) with the events in Pontianak from 23 April 1943 – 28 June 1944 remain very unclear . Whereas other " Class B " war criminals found guilty of professional negligence for atrocities committed by junior staff under their nominal command were sentenced to several years in prison , the speed and secrecy surrounding his trial , and the severity and brutality of his punishment , have created questions which remain unanswered
