This is a Nambu Tekki (cast iron) teapot from the Nambu region. It seems the company is already out of business, making this a valuable item. I purchased it a long time ago, around 15,000 yen, though I don't quite remember when. I've disposed of the box, but it has been stored unused. It's in beautiful condition with no rust or scratches. #NambuTekki #Sangendo #Teapot #IronTeapot #TeaCeremonyUtensils
