By the imperial edict of August 20, 1919, military Sotoku system was abolished, which allowed a civil officer to assume the Sotoku post subject to the system, but this didn't realize in reality, and all the Sotoku other than Saito were Army Generals.
1919年8月20日勅令により総督武官制を廃止し、制度上は文官でも総督就任可能としたが、実際には実現せず、斎藤以外の総督はすべて陸軍大将だった。
