During the Muromachi period, according to the Diary of Emperor Gonara for example, the emperor was initiated in saninsanmyo (namely, three mudra gestures and three mantra chants), performed the first mudra before reaching the Takamikura, and then did the second and third mudra chants after sitting on the Takamikura.
室町時代は、例えば後奈良天皇の宸記によれば、三印三明（つまり三つの印相と三つの真言）の伝授を受け、高御座へ進むまでに第一の印相を結び、着座後に第二、第三の印相を結ぶ方式をとっている。
