A Master Devoted to a Lifetime of Craft — The Art of Icchin Kōchi
In the world of Kyo-ware and Kiyomizu-ware, each artist brings their own unique expression. Among the most technically demanding techniques is Icchin Kōchi.
This traditional Kyoto pottery technique involves delicately applying raised slip lines to the bisque-fired surface, then glazing the piece with a vibrant, glass-like overglaze known as kōchi-yu.

Kōchi glazes are known for being highly fluid before firing, requiring expert control of kiln temperature. When done well, the results are breathtaking—vivid colors and lustrous surfaces that catch the eye and the heart.
A Potter Who Dedicated His Life to Icchin Kōchi

Ichinyo Yamamoto is a ceramic artist who has devoted his entire life to mastering this intricate and brilliant technique.
Born in Osaka in 1949, he trained under the renowned master Suiran Nakamura and later established his own kiln, gaining recognition from many prestigious ceramic institutions in Japan.

While he has received numerous awards in national competitions, Yamamoto remains humble and continues to quietly pursue excellence in his handmade ceramic works.
Still Creating, One Piece at a Time

Now working from a studio attached to his home, Yamamoto carefully creates each piece in small batches, paying close attention to his health and process.
“I want more people to see my work. I want to leave behind something truly good.”
His quiet words reflect a deep and enduring passion for traditional Japanese craftsmanship.
The vivid and intricate beauty of his Icchin Kōchi pottery continues to leave a lasting impression and adds another chapter to the rich legacy of Kyoto ceramics.
