More Information

Uniquely Handcrafted
Each Koo matcha bowl is shaped entirely by hand by Japanese artisan Taro Kojima, whose pieces are made one at a time.
While this artwork can be recreated on demand, no two bowls are ever identical.
Subtle differences in rim, tone, and pottery glaze pattern give each piece a personal and unrepeatable presence.
A Living Landscape in Layers of Hand Decoration
The hand-made decorations evoke blooming sakura branches reflected over calm water.
Soft hues of azure, beige, and pink blend through the glaze, revealing shifting reflections under natural light.
The gentle imperfections of this artisan matcha bowl, born from fire and clay, embody the wabi-sabi spirit of Japanese aesthetics.
The Unboxing Experience
The Koo matcha bowl arrives in a traditional Tomobako (共箱) made of paulownia wood, a presentation box long used in Japan for valuable handcrafted pieces.
The box is finished with handwritten calligraphy and the artisan’s seal from Nunobiki Kiln, marking the bowl as an authentic work of Japanese craftsmanship.
More than protective packaging, the Tomobako serves as a sign of origin, care, and artistic legitimacy, strengthening the connection between the piece and its maker.

Care Guide

About your Koo Matcha Bowl
An artisanal work designed to be used and enjoyed, not just kept in a museum. However, like all fine things, it appreciates gentle handling.

Maintenance

No Harsh Appliances: Avoid the oven, microwave, and dishwasher to protect the handmade finish and delicate decoration.
Gentle Cleaning: Rinse with warm water and a mild soap, using a soft sponge. Dry thoroughly with a soft cloth to prevent water spots.
Preservation Over Time: Do not leave liquids inside for long periods, as natural glazes can absorb moisture.
With regular use and care, the bowl will develop a deeper tone and quiet character.

The Artist

Taro Kojima

Location: Higashiomi, Shiga Prefecture, Japan
Technique: Nanasai Tenmoku
Tradition: Kyoto ware / Shigaraki ware

Born in 1940 in Miyagi Prefecture, Taro Kojima spent his formative years training across Kyoto and Shigaraki, absorbing two of Japan's most distinct ceramic traditions before establishing Nunobiki Kiln in Higashiomi City, Shiga Prefecture.

Nestled near the shores of Lake Biwa, the kiln is a family endeavor where monozukuri is not a philosophy but a daily rhythm. Working with Shigaraki clay, prized for its coarse grain and its deep affinity with fire, Kojima-san approaches each piece as a singular event.

His signature Nanasai Tenmoku glaze is applied entirely by hand. Through firing, it transforms into deep transparency and varied color, capable of rendering natural imagery directly onto the clay, making every piece genuinely unrepeatable.

Cultural Notes

The Spirit Within the Matcha Bowl

In tea culture, a traditional Japanese matcha bowl (抹茶碗, chawan) is far more than just a vessel; it represents harmony, respect, and purity — the core values of the tea ceremony.

Each bowl is chosen not for perfection, but for the emotion it evokes; its weight in the hands, its texture under the fingers, its quiet balance in the moment of use.

During the chanoyu (茶の湯), a matcha bowl for tea ceremony, becomes a bridge between host and guest, embodying wabi-sabi (侘寂) , the appreciation of imperfection, impermanence, and the beauty of restraint.

The Koo matcha bowl carries this spirit into the present, inviting calm reflection and mindful enjoyment with every use, a dialogue between the maker, the clay, and you.

Each Koo matcha bowl is shaped and painted by hand at the Nunobiki kiln, where craftsmanship meets quiet beauty.
No two are the same; every bowl captures a fleeting moment between clay, glaze, and fire.

Featured Focus

Koo: Sakura Reflected on the Lake

The name Koo (湖櫻) joins two kanji:

湖 (ko,lake) honors Lake Biwa, in Shiga Prefecture, Japan’s largest lake and home to the Nunobiki kiln, where calm waters mirror the sky and mountains.
櫻 (ō, cherry blossom) evokes the brief, luminous beauty of cherry blossoms, a reminder that beauty lives in each passing moment.

Together, they form a vision of petals drifting across still water.

The Koo matcha bowl captures that quiet scene in glaze: pink like blossoms, azure like the lake, and beige like the earth that anchors them.
Koo invites you to hold a moment of Japan’s serenity in your hands.
