Koishiwara ware (小石原焼, Koishiwara-yaki) is a traditional Japanese stoneware produced in the village of Toho, Asakura District, Fukuoka Prefecture. It is renowned for its rustic charm, everyday utility, and distinctive decorative techniques that emphasize rhythm and texture.

History

Koishiwara ware traces its origins back to the early Edo period, around the 17th century. Potters from Karatsu, under the guidance of Kuroda domain officials, established kilns in the Koishiwara area to produce durable, practical wares for daily use. Over time, Koishiwara developed its own aesthetic identity, influenced by Korean potting traditions and local innovation.

In the 20th century, the style gained national attention when it was featured in the Japanese folk craft (mingei) movement led by Yanagi Sōetsu and Bernard Leach, who praised its beauty in simplicity and its connection to rural craftsmanship.

Characteristics

Koishiwara ware is primarily stoneware, fired at high temperatures. Its characteristic decorations include:

• Tobikanna (飛鉋) – a “chattering” pattern created by a vibrating metal tool while the pot spins on the wheel.
• Hakeme (刷毛目) – brush stroke designs made with white slip.
• Nagashi (流し) – pouring or dripping glazes to create flowing, organic patterns.

The colors typically range from earthy browns to warm creams and greens, often with natural ash or iron glazes. The emphasis lies on function and tactile beauty, making Koishiwara ware suitable for daily tableware such as bowls, cups, and plates.

Present Day

Today Koishiwara ware continues to be produced by numerous family-run kilns in Toho Village. The community remains active in preserving traditional methods while encouraging modern interpretations. In 1975, Koishiwara ware was officially designated as a Traditional Craft of Japan by the Ministry of Economy, Trade and Industry (METI).

Annual pottery festivals and exhibitions attract visitors from across Japan, ensuring the continuation of this long-standing craft tradition.
