I'm organizing dishes and vases I received as gifts that I haven't used at home because I haven't had the opportunity. The image shows a ceramic piece with the mark "Kozan" on the bottom. "Kozan" is a common art name used by Japanese ceramic artists. To identify which artist created this particular piece, it's necessary to examine the style, kiln characteristics, and other details. Works featured on the Kozan kiln website were priced in the hundreds of thousands of yen. Please note that the wooden base is not included in the sale.
