Kotobuki Japanese yellow ceramic leaf plate Asian soap trinket dish saucer 6x5"

According to my research this yellow leaf plate was made by Kotobuki of Japan. Sometimes their pieces have been sold at Crate and Barrel. I think this may have originally come with a matching cup but I only have the plate. It would work as a soap dish or use it as a trinket dish or anything else. Measures about 6" x 5". No defects noted. Smoke- and pet-free home.
