Japanese teapot themed cast iron trivet by Oitomi

This teapot themed trivet is 5.5" in diameter and sits a bit over .25" high. It has a very small "MADE I N JAPAN" label but no maker's mark. I have seen this same style of teapot pictured on several Iwachu trivets and the quality of the workmanship on this trivet is comparable to Iwachu. I eventually found this driver for sale on Kick I'd web site. Possibly made for domestic use in Japan, but export too. A nice find for $4.

I did also find a nearly identical trivet on ebay Japan, with a foundry mark, described as "[New] Nanbu Tekki bottle sill Daitokuji iron kettle type pot sill 45".
