Mr. Kato was born in Tajimi, Gifu Prefecture in 1902. He studied ceramics in Kyoto and received a bronze prize at the Kyoto Ceramic Craft Encouragement Association in 1936. In 1953, he was honored as a ceramic artist for creating tableware for Their Majesties the Emperor and Empress. His works are characterized by dark blue overglaze and a sense of weight in the sometsuke (blue and white porcelain). The kiln was continued by the first and second generations, but it has been discontinued due to the lack of a successor. However, his meticulously crafted works are still highly popular today. Thank you for viewing. There are many works by Mr. Kato, but I believe that those sets with sashimi bowls and small tamari bowls are not often seen on the market. I have checked each piece, and there are no noticeable scratches. I believe these items are now quite valuable.
