Ishiguro died on 8 January 1950.
His son, Takuro, was an Army captain who was killed in action. This may be partially incorrect as there is a 1st Lieutenant Takuro Ishiguro of the 34th Sentai who was killed in action during the bombing of Wewak on 20 August 1943. He could have been posthumously promoted to the rank of Captain as this was not unusual in the Japanese military.
