Oh nooooo! I got something wrong!
When I wrote about Japanese Yokai, I really did a lot of research. But the thing is, sometimes something slips by. And so it happened! When I wrote about Nabebozu, I noted that it looked a lot like Kamagami. But as it turns out, although my bottle cap figure is Nabebozu, the one standing on an oven is in fact a third spirit, Narikama! I have corrected the text in the article (go take a look), but if you feel really lazy, you can just read below:
Narikama, pictured in the figure above, is a living kettle. He is similar to Nabebozu, who is a living pot, and Kamagami, who is a living rice pot, but entirely distinct. Narikama is “The Ringing Kettle,” a Tsukumogami whose ringing sound signals good fortune.
