This is from when I ran a teahouse on the banks of the Kamogawa River in Kyoto. It's from my great-grandfather's collection, who collected Onmyodo-related items. The era is from the Taisho period to around the early Showa era (early 1900s). It's used for warming sake, but it's like, "Wow, such a magnificent piece!" The craftsmanship is impressive, especially the way the details are hammered out. It's a very rare item, but I have no use for it, so I'm putting it up for sale.
