This is a handcrafted Bizen ware (備前焼) flower vase created by Japanese ceramic artist Kenji Takenaka (竹中健次). Bizen-yaki is one of Japan’s oldest ceramic traditions, dating back over a thousand years, and is highly valued for its natural, unglazed finish that emerges from long, high-temperature wood-firing. The natural ash deposits and reddish-brown hues—achieved without any applied glaze—are the hallmark of this technique. This particular piece features a bold, minimalist silhouette with a tall, narrow neck and robust cylindrical body. Its surface bears natural kiln changes (yōhen) and subtle gradients of earthy tones ranging from warm reds to sandy browns. The texture is richly varied, with fine speckling and areas of smooth sheen contrasting with rougher patches, creating a tactile and visual depth unique to Bizen ware. The vase comes housed in its original wooden storage box (tomobako), signed and sealed by the artist, along with the protective cloth and accompanying certificate. This set ensures the authenticity and collectible value of the piece, making it a fine addition to any collection of Japanese ceramics or wabi-sabi-inspired interior display. About Bizen ware (備前焼) Bizen ware is a traditional Japanese pottery with over a thousand years of history, originating around the end of the Heian period (12th century) in the Bizen area of Okayama Prefecture. It is one of Japan’s oldest and most respected types of ceramics, part of the group known as the Six Ancient Kilns of Japan. What distinguishes Bizen ware is that it is made without any glaze, using a natural clay mixture that is fired at high temperatures (about 1200–1300°C) for more than ten days in wood-fired climbing kilns. This firing process creates unique natural patterns and textures on the surface of each piece, making each item distinct with variations like "goma" (ash deposits), "hidasuki" (red scorch marks), and other kiln effects. The unglazed, hardened ceramic body results in a rustic, warm appearance prized for its earthy beauty and durability—Bizen ware is reputed to be sturdy enough to withstand being dropped without breaking. Its porous texture enhances the flavor and aroma of sake or tea when used as vessels, and it can preserve water freshness when used as vases. Historically, Bizen ware saw royal patronage in the Momoyama and Edo periods and experienced a revival in modern times thanks to national treasure artists. Today, it remains a highly valued craft, blending ancient tradition with natural aesthetics. About Kenji Takenaka (竹中健次) Kenji Takenaka is a contemporary Bizen ware artist who began his career as a jewelry designer before turning to ceramics. After completing his training at the Bizen Ceramic Center and serving as an instructor there, he studied under the Living National Treasure Jun Isezaki in 1988, acquiring the traditional techniques of Bizen pottery. In 1993 he built his own semi-underground anagama kiln, and since establishing his independent studio the following year, he has been actively exhibiting his work in solo and group shows throughout Japan. His creations are known for the natural kiln effects and ash deposits produced by wood firing, as well as the deep, expressive black surfaces of his “Kuro-Bizen” pieces made with specially applied clay. Blending a strong material presence with refined, modern forms, his work has earned high regard among collectors. Pieces accompanied by the artist’s signature or original wooden box (tomobako) are especially valued, as they embody both functional usability and the aesthetic presence of fine art.
