Ember Grove Kyusu

The surface of this kyusu recalls weathered bark, with fine, irregular markings running across its broad, shallow body. Dark, earthy tones dominate, interrupted by soft reddish-brown patches that bring warmth to the textured clay. This variation in color is known as yōhen (窯変), referring to changes that occur in the kiln. During firing, parts of the teapot are covered with rice husks, causing the clay beneath to develop reddish tones while the uncovered areas remain dark. The interplay of color and relief gives the teapot a natural, quietly expressive character.

The gently domed lid is covered in delicate radial markings that spread outward from its elongated knob. Around the body, shorter, more irregular impressions create a contrasting texture. The long side handle widens towards its open end, balancing the teapot's generous proportions, while the short spout maintains its compact silhouette.

Inside, a multi-hole clay filter retains the leaves during pouring. The wide, shallow interior provides ample room for Japanese green tea leaves to unfold, combining practical brewing qualities with a distinctive handmade appearance.

About Gyokko

Founded in 1961, Gyokko is a family-run shokunin pottery workshop in Tokoname, one of Japan's Six Ancient Kilns. Now in its third generation, the studio produces handmade Japanese teaware, including kyusu teapots, shiboridashi and tea cups, combining traditional craftsmanship with precision, functionality and understated beauty.

The production of a Gyokko teapot involves around 40 steps, shared among experienced craftspeople. The body, lid, spout and handle are individually shaped and carefully assembled. Particular attention is paid to the fit of the lid, the angle of the spout for a clean pour, and the position of the handle for comfortable use. The result is teaware that combines the subtle character of handmade ceramics with the reliability and refinement of skilled craftsmanship.

Below is a video of our visit to the Gyokko workshop in Tokoname, where we commissioned the teaware pieces now available at the Nannuoshan shop.

Japanese teaware categories

Japanese teaware can broadly be distinguished into three categories: kikai, commercially produced teaware; shokunin, handmade pieces made by skilled craftspeople; and sakka, works by individual ceramic artists.

Gyokko belongs to the shokunin tradition, where a master develops original designs that skilled potters reproduce entirely by hand. The emphasis is on technical mastery, functionality, and ergonomics. Rather than creating one-of-a-kind art objects, the workshop produces carefully designed pieces that excel in handling and pouring, combining remarkable consistency with the craftsmanship of handmade teaware at an accessible price.
