Description / 商品説明

A refined 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 34.7cm rectangular unglazed pot（長方形無釉鉢） demonstrates the restrained proportions and functional character associated with traditional Tokoname bonsai ceramics. The strong rectangular geometry is softened by gently outward-flaring walls （外開き）, producing an elegant transition from the lower body toward the upper rim.

The upper perimeter is finished with a clean, subtly projecting rim（外縁）, providing definition around the planting area while maintaining the pot's understated character. The restrained projection gives the vessel visual strength without adding unnecessary heaviness.

The lower structure is particularly well defined by a double basal band（二重下帯）, creating two horizontal lines above the feet. This architectural treatment visually anchors the vessel and gives the lower body additional depth and definition, contributing to a strong sense of 均衡 (kinko – balance), 調和 (chowa – harmony) and 安定感 (anteikan – stability).

The pot is supported by four neatly formed straight-cut feet（直切足）, positioned toward the corners and angled subtly outward （外向き）. Their clean geometry complements the rectangular body while giving the vessel a stable, slightly elevated stance.

The fine-grained Tokoname clay（常滑土） has an attractive soft grey-brown coloration with delicate natural speckling throughout the body. Fired unglazed（無釉）, the surface retains the inherent character of the clay, producing an understated 土味 (tsuchi-aji).

Age and cultivation have established a subtle natural surface sheen and gentle 経年変化 (kenen henka), creating an increasingly mature 景色 (keshiki) across the clay. The combination of the subdued colour, fine texture and restrained form gives the pot a particularly appealing 渋み (shibumi).

The interior is neatly finished, with crisp internal corner treatment and a practical arrangement of drainage and wiring holes（排水穴・針金穴） for secure bonsai cultivation.

The underside carries Keizan's impressed 桂山印, confirming this as a Seal Only（印のみ） example from the Hisada workshop.

The combination of 外開き, refined 外縁, 二重下帯, straight-cut feet and mature unglazed Tokoname clay creates a quietly powerful container in which function and aesthetic restraint work together — 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 the family's ceramic tradition and became particularly associated with traditional Tokoname bonsai containers, especially refined unglazed pots（無釉盆栽鉢） in which the natural character of the clay remains an important part of the composition.

His work demonstrates a careful understanding of proportion, horticultural functionality and the relationship between pot and tree. Rather than dominating a bonsai composition, the restrained geometry and natural Tokoname clay（常滑土） provide a complementary foundation from which the tree can remain the principal visual focus.

With continued cultivation, his unglazed pots develop increasingly individual 土味, 経年変化 and 景色, expressing the qualities of 渋み (shibumi – understated refinement), 品格 (hinkaku – dignity) and 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 Tokoname ceramics places his work within an important period of post-war Japanese bonsai-pot history.

This 34.7cm 長方形鉢 is an excellent example of Keizan's restrained unglazed work. Its gently opening walls （外開き）, projecting 外縁, distinctive double basal band（二重下帯）, clean 直切足, and subdued grey-brown 常滑土 combine to produce a pot of considerable 均衡・渋み・品格.

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

At this stage in Keizan's exceptionally long life, vintage examples of his work provide a tangible connection to an increasingly senior generation of Tokoname craftsmanship. The developing 土味・経年変化・景色, together with the disciplined proportions and functional 用の美, make this pot both an accomplished bonsai container and an appealing example for a serious collection of traditional Japanese bonsai ceramics.
