Description
A unique and expressive round Shohin-sized bonsai pot by Juko Koyo (Kuniaki Aiba), the second-generation head of the renowned Koyo Kiln. This piece features a dynamic blend of green and yellow glaze with a deep red splash across one side — a vivid accent that gives the pot an unmistakable character. Its rounded form and lively color contrast make it ideal for use with trees that need a strong visual balance or for creating focal points in Shohin compositions.
Kuniaki Aiba (b. 1973) continues the legacy of his father, Aiba Koyo (Koichiro Aiba), who founded the Koyo kiln in 1970 and became famous for his mastery of glazes. While deeply rooted in that tradition, Juko Koyo introduces his own contemporary energy through experimental glaze combinations and modern aesthetics.

About Juko Koyo and the Koyo Kiln:
Ceramic Name: Juko Koyo (樹晃 鴻陽) Real Name: Kuniaki Aiba
Kuniaki Aiba, working under the name Juko Koyo (樹晃 鴻陽), represents the second generation of the esteemed Koyo Kiln lineage. The kiln was founded in 1970 by his father, Aiba Koichiro (1944–2022), under the name Koyo Toen. Koichiro was celebrated for his wide range of forms and his exceptional glazing techniques, particularly his Oribe-inspired green glazes — rich in texture and depth, evoking the classical works of Tofukuji.
Since taking over the kiln, Juko Koyo has carried on this legacy while infusing the work with his own bold stylistic elements. His pieces often feature creative glaze combinations and modern silhouettes, pushing the boundaries of traditional bonsai pottery while maintaining functional excellence. The red splash seen on this pot is a signature example of his energetic and modern approach.
The Aiba family represents three generations of dedication to ceramic excellence. While his father’s works are under the signature 鴻陽, Kuniaki now signs his pots as 樹晃. A new kiln — Momiji-gama (Maple Kiln) — has recently been opened, ensuring the family’s legacy continues into the future.
