Care Guide

About Your Japanese Matcha Bowl

Cleaning Recommendations
Do not use your handcrafted matcha bowl in the oven, microwave, or dishwasher.

Where it's Made

A Family Kiln, a Living Tradition

Within this quiet setting, every bowl is formed, glazed, and fired by hand, guided by experience passed through generations.

Here, quiet luxury is not defined by perfection but by presence, the subtle beauty that emerges when time, fire, and the maker’s spirit come together.

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.

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.
