Koyama Yasuhisa is a contemporary Japanese ceramic artist and a master of Shigaraki forms. He was born in 1936, and in his lifetime, he has been a forerunner of reviving the art of shigaraki, bringing it into the stage of contemporary craft. His pioneering spirit comes through in all stages of his craft. He was the first potter to construct a modern anagama (tunnel “cave” kiln) for his ash-glazed and unglazed surfaces, reviving medieval ceramic techniques imported from China to Japan during the Tang dynasty via maritime trade. Koyama has a great sense for surface texture and its relationship to form, as demonstrated in this vase; His talent has earned him widespread praise and an illustrious career spanning over 3 decades of solo exhibitions. His works are held in the permanent exhibitions of the Metropolitan Museum of Art, the Brooklyn Museum of Art, the Cleveland Museum of Art, the Stedelijk Museum, and more.
