Ryoji Koie (鯉江良二), Japanese, 1938–2020

A Shigaraki Guinomi (信楽 ぐい呑) 

Showa Era (1926–1989) or Heisei Era (1989-2019)

About the work

This Shigaraki guinomi by Ryoji Koie exemplifies the artist’s radical yet deeply material-driven approach to Japanese ceramics. Compact and resolute in form, the cup is hand-built with subtly irregular walls and a gently uneven rim, emphasizing tactility and the presence of the maker’s hand.

The surface displays the warm, earthy orange tones characteristic of Shigaraki clay, punctuated by natural feldspar inclusions and faint firing marks. Incised lines and surface abrasions remain visible beneath the ash-softened texture, reflecting Koie’s interest in raw process and intentional imperfection. The interior retains a granular, dry feel, enhancing the sensory experience when used.

The piece is accompanied by its original signed wooden box (tomobako), confirming authenticity.
