Tamadare Five-Sided Matcha Bowl Chawan

The Tamadare Five-Sided Matcha Bowl embodies the quiet sophistication and raw elegance of Bizen ware, where natural forces and human dedication converge under the mastery of Mori Toshiaki. Its gently flowing five-paneled structure stretches organically from a pentagonal foot, creating balance between structure and spontaneity. The surface is adorned with the goma pattern, delicate sesame-like specks formed by the melting ash of Japanese red pine during firing. Trails of tamadare glaze—where molten ash pools and drips—grace the rim with a fluid, unrepeatable beauty.

Achieving this unique yet balanced pairing of form and glaze demanded extraordinary patience and precision. The bowl underwent multiple firings in a noborigama climbing kiln, carefully positioned to allow ash to accumulate and flow naturally. Only when placed on the topmost, front-facing shelf—where flame and ash move most freely—did the cascading trails of tamadare emerge. Such a technique carries inherent risks, as the unpredictable behavior of flame and ash can yield unanticipated outcomes. Yet, it is precisely this interplay of control and serendipity that defines Mori’s work, transforming each piece into a refined expression of nature's dynamism.

Mori blends reverence for tradition with a spirit of innovation. The bowl’s softly contoured panels and sculptural foot reflect his philosophy of harmonizing deliberate design with organic spontaneity. Completely unglazed, its surface relies entirely on the transformative power of fire, guided by Mori’s practiced hand and the elemental alchemy of the kiln.

This chawan invites a meditative connection with its user. The unglazed Bizen clay enhances the flavors of the tea, while the bowl’s flowing contours and grounding presence foster a moment of calm reflection. The Tamadare Petaled Matcha Bowl embodies the timeless artistry and elemental spirit of Mori Toshiaki, honoring both function and beauty in its quiet refinement.

Mori Toshiaki

Among the esteemed lineages known as the Bizen Rokusei, or Six Ancient Kilns of Bizen ware, Hozan Kiln stands out as a venerable institution. Mori Toshiaki, the 19th-generation successor, masterfully upholds this rich tradition while pioneering new possibilities. Balancing his responsibilities at the kiln with his personal artistic pursuits, Mori conducts extensive research and explores innovative approaches in both shaping and firing techniques, pushing the boundaries of Bizen ware.

Bizen Ware is a traditional stoneware produced in the Imbe area of Okayama Prefecture. It is one of the oldest ceramics in Japan, and is made using the “Yakishime" technique, in which pieces are fired at high temperatures without glaze to make them durable and water-resistant.
Bizen Ware is called "the art of clay and fire" for the exquisite colors and patterns produced by the kiln's flames, and is characterized by its minimalist, "wabi-sabi" design.
