Ōeyama (Japanese: 大枝山), also known as Ooe-yama and Mount Ooe, is a mountain in Kyoto Prefecture, Japan.
Oinosaka-toge Pass (老ノ坂峠) is located on the north-side slope of this mountain.
People using the San'indō Road from Heian-kyō, passed through Oeno-seki (the Oe gate station) placed on Oeno-saka Slope, located in the boundary between Yamashiro Province and Tanba Province, in order to bid farewell to the capital; therefore, it was known as a place of utamakura.
Due to its strategic location from a transportation and military perspective, it was recorded that, in Jowa Incident and in Hōgen rebellion, many were stationed to prevent suspicious persons from entering or exiting the capital.
A kubizuka where the head of Shuten-dōji is supposed to lay is said to exist on the south side of Oino-saka-toge Pass.
