The Masters Behind Edo Kiriko: Japan's Certified Traditional Craftsmen
Summary: Japan's certified Traditional Craftsmen (伝統工芸士) represent the highest level of mastery in Edo Kiriko. As of 2025, only 23 artisans hold this designation — each one tested, recognized, and carrying forward a craft tradition that began in 1834.
Every Edo Kiriko glass is made by hand — but not every hand is equal. Behind the finest pieces in this tradition stands a small group of artisans who have earned Japan's highest recognition in their craft: the title of Traditional Craftsman (Dento Kogei-shi, 伝統工芸士).
As of March 2025, only 23 people in Japan hold this certification in the field of Edo Kiriko. This is the story of three of them — their paths, their philosophy, and the work that defines them.
What Is a Traditional Craftsman Certification?
Traditional crafts in Japan — including Edo Kiriko — are defined by two requirements: the main production processes must be done by hand, and the techniques involved must be of a high traditional order. Mastering these techniques takes years. Proving that mastery takes more.
The Traditional Craftsman certification (Dento Kogei-shi) is awarded by Japan's Ministry of Economy, Trade and Industry to artisans who demonstrate an exceptional command of the traditional techniques of their designated craft. Candidates must have at least 12 years of professional experience and pass a rigorous technical examination.
In numbers: As of March 2025, only 23 artisans hold the Traditional Craftsman certification in Edo Kiriko — out of a field that spans hundreds of active practitioners across Tokyo.
The certification is not a lifetime achievement award. It is a mark of current, active mastery — a recognition that the holder's hands are, right now, producing work at the highest level of the tradition.
細小路 圭
Kei HosokojiBorn 1982, Okayama Prefecture · Certified Traditional Craftsman 2019
"I think about the value and possibility of Edo Kiriko in the modern era. Sometimes I seek new expressions and techniques that go beyond the framework of traditional crafts — because I want to create a contemporary Edo Kiriko that is loved by many people."
Kei Hosokoji brings a restless creative energy to a tradition that prizes exactness and control. His work is technically precise — award-winning at the highest level — but it never feels static. Hosokoji is consistently pushing at the edges of what Edo Kiriko can be, without losing sight of what it is.
His pieces range from delicate whisky cups to large-scale decorative works, each revealing a mastery of the grinding wheel matched with a clear personal vision. He was certified as a Traditional Craftsman in 2019, the same year he won his third major award at the Edo Kiriko New Works Exhibition.

山田 のゆり
Noyuri YamadaBorn 1984, Kanagawa Prefecture · Certified Traditional Craftsman 2020
"I believe Edo Kiriko has the power to draw people in — to give hope to those who see it. I think that power is what makes it beautiful. I want to learn and grow every day, starting from zero."
Noyuri Yamada approaches her craft with both humility and quiet conviction. Her statement — that Edo Kiriko gives hope to those who see it — is visible in her work. Each piece carries a warmth and presence that extends beyond its technical execution.
Certified in 2020, Yamada has received recognition at the very highest level of the craft, including the Minister of Economy, Trade and Industry Award — one of Japan's most prestigious honors in traditional craft. Her work spans delicate sake cups, sculptural bowls, and whisky glasses that reward close attention.

Taro KikkawaBorn 1988, Tokyo · Certified Traditional Craftsman 2023
"I want to become as skilled as my seniors as quickly as possible, and support this industry even a little. For that, I want to work hard — humbly and stubbornly."
Taro Kikkawa is the youngest of the three craftsmen, certified in 2023, and his stated ambition reveals someone who understands exactly where he stands in a long tradition. The words "humbly and stubbornly" say everything: this is a craftsman who knows the work is never finished.
Despite his relative youth, Kikkawa's award record is already remarkable — back-to-back recognition at the 32nd and 33rd Edo Kiriko New Works Exhibitions. Born in Tokyo, he is a craftsman of the city where the tradition was born, and his work reflects that inheritance.
