Inari Shrine at Yakuoin Temple on Mt. Takao
The grounds for this Inari Shrine are part of the Buddhist temple on Mount Takao formally known as Takao-san Yakuo-in Yuki-ji, and most commonly known as just Takaosan Yakuoin (高尾山薬王院). This place was supposedly established in 744 on the orders of Emperor Shomu as a base for Buddhism in eastern Japan. I have no way of knowing how long these torii and structures have been around, but I think it is safe to say that they are much more recent creations. This shrine has more Shinto characteristics than Buddhist ones.
