Lineage of Living National Treasure Kei Fujiwara, Bizen Ware Artist Mizutani Tosui (水谷陶酔): Unglazed Stoneware Hidasuki Deformed Guinomi with Dedicated Tomobako, Japanese Rocks Glass #348

Hand-kneaded deformed Bizen guinomi (sake cup) created by Tosui Mizutani (水谷陶酔, 1949–; real name: Kiyoshi Mizutani), a Bizen ware artist born in Akaiwa District, Okayama Prefecture in 1949 (Showa 24). In 1972 (Showa 47), Tosui Mizutani apprenticed under Seinosuke Ohira, a direct disciple of Kei Fujiwara—the very first Living National Treasure of Bizen ware—and under strict guidance mastered the traditional pottery techniques of Old Bizen and the art of drawing out the clay's natural character. Encouraged by Mizutani's master, the artist became independent in 1978 (Showa 53), building Mizutani's kiln in a scenic area on the outer grounds of the National Treasure Shizutani School and firing Mizutani's first kiln load. Subsequently, the artist was selected numerous times for the Okayama Prefecture Art Exhibition and held solo exhibitions in cities such as Himeji, Takarazuka, Nishinomiya, and Kurashiki, establishing a firm artistic style as a member of the Bizen Toyukai Association. Our shop presents this work, fired solely through the chemical reaction between wood-kiln flames and clay without applying any glaze, to the global market not only as a traditional sake vessel, but also as a vintage rocks glass (Japanese free cup) for quietly savoring the rich depth of amber-colored aged sake or matured whisky.

Observing the details of this work reveals a splendid harmony between the powerful sculptural sensibility praised in Tosui Mizutani's art and the yohen (kiln transformation) landscape unique to Bizen ware. Hand-sculpted while deliberately avoiding the linear geometry of the potter's wheel, a bold indentation as if forcefully pressed by fingers is applied around the center of the body, combining exceptional functionality that fits naturally in the fingertips when held. On the vessel's sides, vivid reddish-orange hidasuki (fire-cord markings) created by wrapping rice straw during firing emerge clearly in ring-like patterns, creating a dramatic contrast with the smoky dark brown and bluish-gray sangiri (ash-covered reduction marks) enveloping it, as well as the minute goma (natural ash glaze) from melted pine ash. From the organic rim broken from a true circle to the interior base, the texture of undulating clay and scorched landscapes spreads out; when sake is poured, the clay surface absorbs moisture and transforms into a moist, deeply resonant hue.

Regarding the period of production, taking clues from Mizutani's independent kiln founding in 1978 (Showa 53) recorded in the biography leaflet, repeated selections at the Okayama Prefecture Art Exhibition, Mizutani's vigorous solo exhibition activities in major cities, and the mature stage of Mizutani's original sculptural beauty and firing techniques evidenced by signing Mizutani's art name "Tosui" on the box inscription, it is identified as an authentic work created circa 1980 to 1999 (late Showa 50s to early Heisei period). The vessel itself has no cracks or chips, maintaining extremely good condition in both hidasuki coloration and raw clay texture. It arrives as a complete masterpiece accompanied by a dedicated Tomobako (wooden box) inscribed in ink on the lid "Bizen Guinomi" with the signature "Tosui" and red seal stamped below, along with a biography leaflet detailing the artist's history.
