Here is a good looking older cast iron Japanese tea pot. It was brought to this country.In the late 1940's by a local Nebraska couple. Named Tanuki with a leaf hat.
On the opposite side is a string of 6 Japanese characters - a signature? I have attached the message from a very helpful fellow eBayer explaining this. It measures about 10" high by 8" wide.
