Vintage Japanese-Inspired Snack Bowl and Personal Platters (Set of 6)

These cream based porcelaneous glazed pieces have blue rings around the rims, a floral pattern in the bowls, and beautiful rings of brown, blue and green on the exteriors. They appear to be a set, so we are guessing they are a snack bowl and personal footed platters. They also could be Japanese tea cups and saucers, with cups missing, of course.
 
We do not know the origin or date of these treasures. We presume they would have been acquired in the 1970s or 1980s as we have had them around the house for decades.
 
They are in excellent condition, one platter showing a kiln mark on the bottom and two pieces showing what might be called a glaze stain in the floral pattern. 
 
The set includes one snack bowl and five platters.
 
Snack Bowl: H 2 3/8” x 4 7/8”
Platters: H 1” x D 4 3/8”
 
Note: We do not know if these are dishwasher or microwave safe.
