Description / 商品説明

A fine vintage, artisan-made Japanese bonsai pot by Second Generation Hisada Keizan（二代 久田桂山）, Hisada Sadao 久田貞雄, from the Hisada Kiln（久田窯） of Tokoname 常滑市.

This 35.9cm rectangular unglazed pot（長方形無釉鉢） has a strong architectural character, distinguished by its subtly flared corners（隅張り）. Each corner is further articulated by a delicate raised vertical line, adding definition to the silhouette and emphasising the transition from the body toward the feet.

The upper opening is finished with a clean internal rim（内縁）, giving the planting area a crisp and controlled frame. The combination of the 内縁, straight body and strengthened corners produces a particularly convincing sense of 均衡 (kinko – balance), 安定感 (anteikan – stability) and 品格 (hinkaku – dignity).

The vessel is supported by neatly formed cut feet（切足）, positioned to complement the geometry of the rectangular body. Their restrained construction maintains a strong, grounded stance without distracting from the characteristic corner treatment.

The pot is made from excellent Tokoname clay（常滑土）, fired unglazed（無釉） to preserve the natural qualities of the material. Fine speckling across the warm earthy surface gives the clay an attractive 土味 (tsuchi-aji), while natural ageing has begun to establish subtle 経年変化 (kenen henka) and individual 景色 (keshiki).

The understated clay surface and disciplined construction give the pot a particularly appealing 渋み (shibumi). It has enough structural strength to complement a powerful bonsai while remaining visually restrained enough to allow the tree to remain the principal focus of the composition.

The base incorporates six functional drainage and wiring openings（排水穴・針金穴）, providing an efficient arrangement for drainage, root health and secure anchoring of the tree.

The underside is neatly finished and carries Keizan's centrally positioned impressed 桂山印. This is a Seal Only（印のみ） example.

The combination of 隅張り, raised corner detailing, 内縁, 切足 and naturally textured 常滑土 gives this pot a strong yet refined character — an excellent expression of 用の美 (yo no bi – beauty through function).

About the Potter / 作家について

Hisada Sadao 久田貞雄, born in 1930 in Tokoname, is the Second Generation Hisada Keizan（二代 久田桂山). He is the son of Hisada Shizuo 久田静夫, who established the Hisada workshop in Tokoname in 1929.

Sadao continued and developed the family's ceramic tradition, becoming particularly associated with traditional Tokoname bonsai containers and refined unglazed pottery（無釉盆栽鉢）. His work demonstrates a strong understanding of proportion, clay character and the practical requirements of cultivating mature bonsai.

The natural qualities of Tokoname clay（常滑土） are central to his unglazed work. Rather than relying upon decorative glaze, the character comes from the clay itself, its firing and the gradual development of 土味・経年変化・景色 through age and cultivation.

This restrained approach embodies 渋み (shibumi – understated refinement), 調和 (chowa – harmony), 品格 (hinkaku – dignity) and the traditional principle of 用の美 (yo no bi – beauty through function).

Collector's Note / コレクターズノート

Born in 1930, Hisada Sadao 久田貞雄 is now in his mid-nineties and remains a living representative of one of the senior generations associated with traditional Tokoname bonsai-pot craftsmanship. His exceptionally long connection with the pottery traditions of Tokoname places his work within an important period of post-war Japanese bonsai ceramics.

This 35.9cm 隅張長方形鉢 is particularly attractive for its architectural construction. The subtly flared 隅張り corners, delicate raised vertical corner lines, clean 内縁 and restrained 切足 give the pot considerably more character than a conventional plain rectangular form while preserving the understated qualities expected of a traditional unglazed bonsai container.

This particular example is Seal Only（印のみ）, carrying Keizan's centrally impressed 桂山印 as its identifying maker's mark. It should therefore be distinguished from Keizan examples carrying an additional hand-incised 銘.

At this stage in Keizan's exceptionally long life, vintage examples of his work offer a tangible connection to an increasingly senior generation of Tokoname craftsmanship. The combination of distinctive form, natural 常滑土, developing 土味・景色・渋み, and Keizan's impressed seal makes this an appealing example both for practical bonsai use and for a collection of traditional Japanese bonsai ceramics.
