Another shrine called Matsuo-jinja, which is located along the Oi-gawa River, is believed to have had a relationship with the Tsukiyomi-jinja Shrine, a Sessha (auxiliary shrine (dedicated to a deity closely related to that of the main shrine)) of the Matsuo-taisha Shrine (in Kyoto City), which is located in the lower reach of the river.
大堰川沿いには他にも松尾神社があるので、下流の松尾大社の摂社月読神社(京都市)との関係が指摘されている。
