This appears to be a set of individual plates (meimeizara) from the Ume Shonzui (plum and auspicious design) series by Seto Sometsuke-yaki Kinzan Kiln. It seems there was originally a plate in the center as well. This item was found while organizing the home of a friend who moved. I don't know the details, such as when or where it was purchased. I have washed it before listing. I am an amateur, so I may have missed some dirt. Please refer to the images for the size. (There may be some slight errors) I am also listing many other items. (Please note that I may not be able to combine shipping due to shipping and packaging constraints.)
