Made by Shigaraki-yaki ceramic artist KAWASE KOHAI

This exceptional Matcha bowl is a masterful expression of Japan’s ancient ceramic heritage, created using the revered technique of WARA HAIYU - a method rooted in nature, fire, and time itself.

The glaze, formulated from the ash of burned rice straw, produces a softly luminous, milky matte surface of remarkable depth and quiet elegance. Unlike industrial ceramics, whose perfection is controlled and repeatable, this bowl embraces the unpredictable poetry of the kiln. Subtle variations in flame, atmosphere, and mineral interaction give rise to YOHEN - natural kiln transformations that ensure no two pieces can ever exist in the same way.

HAIYU in Japan dates to the 5th century, when natural ash from wood-fired kilns accidentally settled upon Sue ware, creating an unintended glass-like surface. Over centuries, this serendipitous occurrence evolved into a refined aesthetic pursuit. WARA HAIYU remains one of the most organic and technically demanding expressions of this tradition.

Along the rim, iron has been applied over the glaze and fired in oxidation, producing a warm, amber-toned transformation that deepens the visual and tactile richness of the piece. This gentle contrast between the soft bluish white body and the caramel-hued edge creates a quiet yet powerful presence.

KODAI base reveals the artist’s devotion to both heritage and playful innovation. Four carved facets are cut into the base, allowing the form to be felt as much as seen - enhancing the intimate connection between hand and vessel. During firing, a seashell is placed beneath KODAI base, causing the clay to blush into a natural orange known as HIIRO scarlet. This spontaneous, flame-born coloration is never predictable, further affirming the bowl’s individuality. Inside KODAI base, a spiral carving called TOKIN - traditionally associated with RAKU YAKI - has been deliberately incorporated, a refined nod to Japan’s ceramic lineage.

In the tradition of the tea ceremony, one admires the bowl after finishing the Matcha, a practice known as HAIKEN. Only then does its full depth reveal itself: the quiet transitions of glaze, the traces of flame, and the subtle asymmetries shaped by hand. Ownership of such a piece is not simply acquisition - it is participation in a living continuum of culture.

This Matcha bowl offers something increasingly rare in the modern world: authenticity shaped by nature, guided by mastery, and destined to exist only once.
