One of the things I am on the lookout for while I wander the back roads of rural Japan are fertility shrines. Many of them, like this one in Tamatsukuri, Izumo, are not signed, not on maps, and not associated with priests.
The Izumo area has quite a lot of them, though of course tourists don't visit them like they do a couple of the famous ones up in the big cities.
This one had quite a few small, hand-carved Phallii, as well as a few stones representing the female......
This large one was enclosed in a small structure and seems to be the main object. There was also an altar put up by a gentleman in celebration of reaching 100 years of age.
