Likely from the Muromachi period. There is a hole-like scratch on the inside. There is a catch on the rim. It seems like it could be used as a rice bowl or a small bowl. This is a very old item. I have included images of any areas of concern as much as possible, but there may be oversights. If you understand this, please consider purchasing. My family loves old tableware and has collected items from antique shops, items passed down through generations, and items purchased locally. I am gradually letting go of them to declutter. If you like, please take a look at my other items as well, and I can offer a discount if you purchase multiple items and have them shipped together.
