Description
This large rectangle bonsai pot by Yamaaki measures 45,0 × 35,5 × 12,0 cm (outer). Crafted from rich dark brown clay, it reflects the kiln’s refined sense of proportion and balance. The bold rectangular form, slightly flared rim, and sturdy feet give it both strength and elegance, making it ideal for powerful conifer bonsai.
The unglazed surface allows a natural patina to develop with use, enhancing its character over time. Yamaaki pots are highly regarded by collectors and practitioners for their consistent quality, refined details, and timeless aesthetics. This piece is not only practical for growing but also suitable for exhibition display.

About Yamaaki Kiln – Sadamitsu Kataoka
Yamaaki Pottery is the largest producer of high-quality bonsai pots in Tokoname. As a handmade bonsai pot studio, it has passed from the previous master, Jūōdō Shōsen, to the current generation, Shōsen (formerly known as Koshōsen).
About the current Shōsen:
His real name is Sadamitsu Kataoka, the second-generation head of Yamaaki Pottery. He began using the artist name Koshōsen around 1985, and after the passing of his father, Jūōdō Shōsen, he inherited the name Shōsen.
Yamaaki Pottery is known for having one of the largest bell-shaped gas kilns in Tokoname, which allows for highly stable and consistent firing. Most pots are made using molded forms with hand-finishing.
While they also produce glazed ware and small pots, the core of their production lies in unglazed medium and large bonsai pots in natural clay colors. Yamaaki’s signature blend of Tokoname clay and imported Chinese purple clay—known as Tokoname udei (a dark-toned clay body that hardens at lower firing temperatures)—has been highly influential, inspiring many imitators.
