Against the backdrop of the dissemination of “Donabe”casserole pots that do not crack when heated due to the use of heat-resistant raw materials, the Sumikannyu series gained popularity. Meanwhile, Tetsuzo Kumamoto, the second president, developed the Hanamishima line with the Mishima Technique at a time when white “Donabe” with paintings were common. This series become so popular that the supply could not meet the demand and came to be dubbed “the standard for “Donabe”casserole pots.”

The third president Tetsuya Kumamoto, who took over the Hanamishima series, established a production line with a well-balanced arrangement of machinery and workers. The company established a system which specified the craftsmen’s techniques, rather than relying on the intuition of experienced craftsmen, and acquired an ISO 9001 certification. While protecting its long-selling products and listening to the voices of its customers, the company developed original “Donabe”casserole pots as new cooking utensils that matched the flow of the times.
