A teacup with the "Obahai" mark. Shidoro ware is listed as one of the Enshu Seven Kilns, and it is the only kiln among the seven that is said to have been producing since the Muromachi period. A famous example is a tea caddy with the "Obahai" mark. I thought this piece might also be Shidoro ware from the Muromachi period based on its atmosphere, but there are other ceramics with the same "Obahai" mark, such as: * Toyama ware (Rakurakuen ware) of the Owari Domain's private kiln, from the mid-17th century, * Ofukei ware, also from the 17th century, * The Owari Domain's Toyama detached residence (Shinjuku-ku) from the first half of the 19th century, etc. It is unclear which of these this piece corresponds to. I believe this piece is a work from the late 16th century, belonging to the second period of Shidoro ware. Its characteristics are the iron-rich clay and its robustness. As the description suggests, this teacup is fired so hard that it sounds like porcelain. As shown in the image, there are gold repairs on the inside, the side of the foot, and the body's waist. The original box is, as usual, missing, so a storage box and wrapping cloth are included. This is a teacup with an old-fashioned style. Diameter: Approximately 12.3 cm Height: Approximately 6.5 cm The size is approximate. The actual item may differ slightly in color from the image. As it is an old item, there are scratches and stains commensurate with its age.
