According to the writing ''Soban-ki'' by the monk Gyokusyu of Daitoku-ji Temple, a Shomen-kongo statue was found under ashes when Sadamasa's father Sadataka KATAGIRI burned the household furniture, and this statue went on to become the principal object of worship of the temple.
大徳寺玉舟和尚の筆による縁起「宗鐇記」によると、貞昌の父片桐貞隆が家蔵の什器を焼き捨てたとき灰の中から青面金剛像一体が発見され、この像が後に本尊になったという。
