Vintage / Antique 8 piece Japan white floral child's tea cup set 1940s / 1950s

Vintage 8 piece Japan floral child's tea cup set 4 teacups and plates or saucers - white with yellow and blue flowers the plates are super thin, so I'd say these are probably a bone china or porcelain, rather than a ceramic, no guarantees most likely from the 1940s or 1950s plate is about 2 1/2 inches wide, the tea pot is about 1 3/8 tall Marked Japan Preowned Estate Find. See photos for condition, two of the plates have dark spots, and one cup has had the handle repaired and a crack, but you have to look closely to see it. I think that they are handpainted but they are not marked. All in all these a very pretty set set.
