Meet the maker: Ishihara Shōji

Ishihara Shōji (石原祥嗣) is a Japanese ceramic artist born in 1943 in Naogata, Fukuoka Prefecture. He trained as a sculptor before building his own kiln in 1981 and working in ash-glazed stoneware until 1989, when he introduced the coloured Oborodeisai (朧泥彩) technique he is now best known for. His work is held in the Fukuoka Prefectural Museum of Art and is represented by galleries in Japan and New York.

Who is Ishihara Shōji?

Ishihara Shōji (石原祥嗣) was born in 1943 in Naogata, Fukuoka Prefecture, and originally trained as a sculptor, graduating from the sculpture department of Kanazawa College of Art in 1968. He returned to his hometown in 1977 to dedicate himself to ceramics, and four years later, in 1981, built his own kiln, Ishihara Shō-gama, marking the start of his full engagement with the craft. His early work, through the 1970s and into the early 1980s, was rooted in high-fired, largely unglazed stoneware with natural ash-glaze (vidro, ビードロ釉) pooling and carved-slip decoration, a sculptural approach that traces back to his training. From 1989 onward, he introduced the coloured technique he named Oborodeisai (朧泥彩), which became the style he is most widely recognised for today.

He became a member of the Japan Craft Association (日本工芸会) in 1984, and has been recognised repeatedly since: an encouragement award at the Nishi-Nihon Ceramic Art Exhibition in 1982, prizes at the Saibu Craft Exhibition and Japan Traditional Art Crafts Exhibition in 1983, a purchase by Japan's Ministry of Foreign Affairs the same year, and a purchase by the Japan Foundation in 1987. His work is held in the permanent collection of the Fukuoka Prefectural Museum of Art, a 1991 Oborodeisai-period vase acquired in 1997. In 2000 he donated a work to the Kagura-den of Ise Jingū's outer shrine, one of Japan's most significant Shinto sites. In 2009 his work was included in a special exhibition at the Kyushu National Museum. He continues to exhibit new work as recently as 2026, and is represented internationally by Dai Ichi Arts in New York and, in Japan, by Gallery Japan.

His son, Yoshimitsu Ishihara (born 1971, Osaka), also trained under him from 2002 before establishing his own wood-fired ceramic practice in Fukuoka in 2006, also with a background in sculpture.


What sets his work apart

Early work: high-fired stoneware, evenly glazed with a fine crackle, in jade to grey-green vidro-type tones, sometimes with carved or incised decoration, sculptural in feel. Later work (1989 onward): the Oborodeisai style, characterised by soft, layered colour and distinctive form, very different in appearance from the earlier pieces.


How to recognise a genuine piece

  • Tomobako typically signed with the characters 石原祥嗣, accompanied by a red seal 祥 (Sho).

  • Not all early pieces carry a signature on the object itself; the tomobako is often the primary point of attribution for this period of his work.
