Thank you for viewing. This is an Issho Tokkuri (a one-shou sake bottle). It was found in the back of the storage room at my parents' house, and I don't know the details. It says "vinegar" on it, so it may have been used to sell vinegar, or it may have belonged to a vinegar maker. I'm not sure. At least when I was a child, vinegar was purchased in one-shou bottles, so I think it's an old item. Would you like it for your collection?
