I believe this is Arita-yaki or Imari-yaki. It features vibrant red painting and decorative artwork. Smaller than a typical teacup, this is a "sencha yunomi" (small size), perfect for enjoying sencha or gyokuro tea in small portions for guests. Size: Diameter 7.8cm Height 5cm No chips or scratches. It has been stored at home for a long time without being used, so your understanding is appreciated.
