According to a legend handed down in Kumata-jinja Shrine and so on in the area, Masamichi "lived in Hiranosho of Settsu Province, its kaihatsu ryoshu (a local notable who actually developed the land) being SAKANOUE no Hirono, where he succeeded to the property of the SAKANOUE clan after Hirono and established Gion-sha Shrine [present Kumata-jinja Shrine] enshrining Susanoo no mikoto."
同地の杭全神社などの伝承によれば、当道は「坂上広野を開発領主とする摂津国平野庄に住し広野の後の平野の坂上氏の家督を継ぎ、素盞嗚尊を勧請し祇園社（現在の杭全神社）を創建した」とされる。
