Item Description This exquisite chawan (tea bowl) is a work of Tobeyaki pottery — a traditional ceramic art from Tobe Town, Ehime Prefecture, designated as a Japanese National Traditional Craft. This is a signed, artist-made piece from the Teizangama kiln (Iwata Seitousho), one of the established workshops of the Tobeyaki Cooperative Association. The bowl is covered in a rich, deep iron-black glaze (tenmoku-style) that shimmers with scattered yellow-green speckles reminiscent of a star-filled night sky — an effect known as "yuteki" (oil-spot), where mineral crystals rise to the surface during high-temperature firing, creating an otherworldly, luminous appearance. The rim is adorned with a warm iron-red band that transitions seamlessly into the dark body glaze, lending the piece elegant warmth and depth. The interior is equally mesmerizing: the same dark tenmoku glaze coats the full inner surface, alive with golden-green speckled crystals that catch and reflect light beautifully — ideal for appreciating the color and foam of whisked matcha. The foot ring (kodai) is left unglazed, revealing the pale cream-white stoneware body beneath. The piece is accompanied by its original signed wooden box (tomobako), inscribed with "Tobeyaki Chawan" and bearing the artist's signature with a red seal. The underside of the bowl bears the impressed "Teizansou" seal mark. Size Height: 7 cm Width: 12.5 cm Depth: 12.5 cm Weight 261 g Condition The bowl is in excellent condition with no chips, cracks, or repairs; the glaze is vivid and intact throughout, and the wooden storage box is clean and undamaged.
