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.

At 37.8cm, this medium-sized rectangular unglazed pot （長方形無釉鉢） has a particularly architectural character, distinguished by its pronounced flared corners（隅張り）. These strengthened corners create a continuous visual line running from the feet through the body and toward the upper rim, giving the pot a powerful yet highly refined silhouette.

The upper perimeter is finished with a defined raised border（縁立て・fuchidate）, accompanied by a subtle internal rim（内縁）. Together, these elements provide a crisp frame around the planting area and give additional visual strength to the mouth of the pot.

The lower body is anchored by a defined basal band（腰帯）, creating a strong horizontal counterpoint to the vertical emphasis of the flared corners. The relationship between 内縁・縁立て・隅張り・腰帯 gives the vessel a particularly convincing sense of 均衡 (kinko – balance), 調和 (chowa – harmony) and 品格 (hinkaku – dignity).

The pot is supported by carefully formed stepped feet（段足）, incorporating subtle incised definition. Their construction continues naturally into the strengthened corners above, visually connecting 足 (ashi – feet), 鉢身 (hachi-mi – body) and 口縁 (koen – rim) into one coherent design. This continuity is one of the most attractive aspects of the pot and gives the form a strong sense of deliberate 造形美 (zokeibi – beauty of form).

The pot is formed from warm natural Tokoname clay（常滑土） and fired unglazed（無釉）, allowing the inherent texture and character of the material to remain visible. The surface has already begun to develop attractive 経年変化 (kenen henka) and a mature 景色 (keshiki), producing the understated character described in Japanese aesthetics as 渋い (shibui).

With continued bonsai cultivation, this natural surface character should continue to deepen, further enhancing the 土味 (tsuchi-aji) and quiet visual richness of the clay.

The underside carries Keizan's impressed personal seal（桂山印） as the identifying maker's mark. This is specifically a Seal Only（印のみ） example.

The combination of 隅張り, 内縁, raised 縁立て, 腰帯 and 段足 gives this pot a stately but understated presence, making it particularly well suited to mature pines, junipers or deciduous bonsai where the container must provide visual strength without competing with the tree.

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 Hisada 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 sophisticated understanding of proportion, clay character and the functional requirements of bonsai cultivation.

Keizan's unglazed pots allow the inherent qualities of Tokoname clay（常滑土） to remain central to their appearance. Through firing, age and continued cultivation, the clay gradually acquires individual 土味, 経年変化 and 景色, qualities especially valued in traditional Japanese bonsai ceramics.

His restrained approach combines 調和 (chowa – harmony), 渋み (shibumi – understated refinement) and 品格 (hinkaku – dignity) with the practical 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 Tokoname ceramics places his work within an important period of post-war Japanese bonsai-pot history.

This 37.8cm 隅張長方形鉢 is a particularly attractive example of Keizan's more architectural unglazed work. The continuous relationship between the stepped feet（段足）, strengthened flared corners（隅張り）, basal band（腰帯）, subtle internal rim（内縁） and raised 縁立て demonstrates careful control of both vertical and horizontal structure.

This particular pot is a Seal Only（印のみ） example, carrying Keizan's impressed 桂山印 as its identifying maker's mark.

Its collector appeal lies not simply in attribution, but in the quality of its construction and the way its unglazed 常滑土 continues to mature. The developing 土味・経年変化・景色・渋み, combined with the distinctive 隅張 form and disciplined proportions, give the pot considerable character without sacrificing its primary purpose as a bonsai container.

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, making this a highly usable pot as well as a compelling piece for a serious collection of traditional Japanese bonsai ceramics.
