Kiyoko Koyama (神山清子), Japanese, (1936-2023)

A Natural-Ash Glazed Faceted Tokkuri (自然釉面取徳利)

Showa Era (1926-1989), Heisei Era (1989-2019) or Reiwa Era (2019 – present)

About the work

A beautifully faceted tokkuri by renowned ceramic artist Kiyoko Koyama, finished in a natural ash glaze. This piece exemplifies the earthy elegance and material integrity of her wood-fired works. While traditionally used as a sake vessel, the piece’s graceful proportions and tapered mouth also allow it to function as a small flower vase.

The body is hand-faceted in vertical planes that catch the kiln’s ash in varying densities. The surface transitions from smoky grays to charcoal blacks, with warm reddish tones near the base—hallmarks of prolonged, directional wood firing. A subtle gloss overlays the textured surface, enhancing the depth and movement of color.

Footnote

Kiyoko Koyama (1936-2023) was born in Sasebo, Nagasaki, and later moved to Shigaraki after World War II. Initially working in ceramic decoration, she shifted to pottery at 30, pursuing the dream of recreating Shigaraki natural ash glazes using an anagama kiln. Over years of dedication and struggle, including building her own kiln, she perfected her craft, earning nationwide acclaim. Koyama held numerous solo exhibitions and became a celebrated figure in Japanese pottery.
