Kousai Kiln is owned by Mr. Hirohiko Umeno, a potter engaged in pottery making in Hasami-cho, Nagasaki Prefecture. He trained at a Kiyomizu ware kiln in Kyoto City and opened his own kiln in Mt. Nakao in 1991. He produces unique pottery based on handmade and hand-painted techniques.
Combining Shigaraki style "Yakishime(high-fired unglazed ceramics)" and traditional "Some-nishiki", his unique style is popular for its fusion of stoneware, which is relatively rare for Hasami ware, and the elegance of Kyo ware style. The unique motifs of the pottery, such as depictions of plants like flowers and grapes, and animals like cats and rabbits, make it fun to choose from a wide variety of pieces.
