Mashiko square plate

This Mashiko "plate" is 8" square x 1.25" high and weighs about 1 lb 13 ounces. It is not marked. This "cherry blossom" design is typically identified as Mashiko. Similar shape and sized pieces are fairly common Mashiko ware and usually described as "plates". Not sure if they have a use aside from "decorative".

Plates like this typically come with a tomobako but if there was one with this plate it has been lost. The seller said it had a box with it and receipt dated 1976, but no further information. I bought this as part of my bathroom Japanese pottery decoration but I did not expect this plate to be so large and heavy. Not sure that I can find a hanger that will hold it. It was super cheap on E of the Bay, no dimensions or weight in the description, so I expected it would be small and thin, perhaps a sauce dipping bowl. So a really good deal but not sure what I will do with it now. I will probably still experiment with hanging it.
