I believe this is Mino ware from the Meiji era, a Yellow Seto platform dish. Details are unknown. It has a traditional yet modern feel with its angled shape and height. The stains from use add to its character. There are three spots of green glaze on the top surface as accents. There are no markings, and the kiln is unknown. Upon inspection, there are small chips on the edges in several places (as shown by the stickers). I have tried my best to check, but there may be oversights. Please understand. This price is for a set of four. Size: Approximately W22.5-D16.5cm H3cm *There are slight variations in size due to being handmade. Similar items with damage are also available at a lower price. I am also selling other antiques. Thank you for your interest.
