Ken Matsuzaki was born in Tokyo in 1950 and received a degree in Ceramic Art from Tamagawa University School of Fine Arts, Tokyo. In 1972, after graduating he moved to Mashiko to apprentice with Tatsuzo Shimaoka, who himself had moved to Mashiko to study with Shoji Hamada. After a five year apprenticeship, Matsuzaki established his own kiln, Yuushin Gama, down the road from Tatsuzo Shimaoka. Matsuzaki's works have a strong grounding in the Mingei philosophy though his approach is very contemporary, introducing a focus on the Oribe style with yohen, shino, and oribe glazing.
Matsuzaki is currently the president of the Mashiko Potters Association. His pottery is amontg the collections of multiple museums including, the Metropolitan Museum of Art, the Cleveland Museum of Art, the Worcester Museum of Art, and the Tikotin Museum in Israel.
