I stumbled across this unusual shrine while biking from Ikebukuro to Nerima. I’ve never seen a shrine built into a house (and a somewhat modern house at that). After researching the name Anamori Inari Shrine, I found that there is a quite large and famous Anamori Inari Shrine in Ota ward, and that this house serves as a local branch office with an extremely small shrine attached to the front.
This has got to be the strangest shrine I have encountered to date. Has anyone else ever seen a shrine like this?
