The architect then figured out a way to get into the Office of Construction as what we would today call a "construction site director," thereby gaining the opportunity to draft the renovation plan. However, it is rumored that he brought his blueprint back to Tokyo to be revised by others, so that it remains a mystery exactly who participated in the design.
於是他設法進入營繕課當現在所謂的「工地主任」，藉以獲得修改設計的機會；不過據傳他還曾拿設計圖回東京請人修改，因此究竟有多少人參與總督府的設計，至今還是個謎。
