This item has been sleeping in my parents' china cabinet for a long time. I'm not an expert on ceramics, but Google Lens identified it as Arita-yaki. Although there's no mention of Arita-yaki on the product itself, the wooden box is marked "Touka Saku" (陶華作), and the teacups are marked "Matsutakara" (松宝) on the bottom. I opened it for the photos, but it's unused. A beautiful set of ceramic teapot and teacups with a blue floral and leaf design. The box has some damage. Please check the photos. Although it's unused, please consider that it has been stored at home. - Set includes: Teapot and teacups - Design: Blue floral and leaf pattern - Bottom markings: Artist's signature - Material: Ceramic - Box: Comes with a wooden storage box Thank you for looking.
