The popular form of Koshin worship is now associated with the famous three monkeys and also with Sarutahiko. Statues of monkeys are therefore often found at Koshin sites.
At the Koshinsha in Nogata there were dozens and dozens of them, though my favorite must be the one in the first photo. A very happy monkey.
The eclectic collections of statues and dolls left by devotees at sacred sites popular in what is called "folk" religion around Japan intrigue me.
The figure below, a monkey carrying a gohei. a purification wand, is something I have seen a few times before.
