A warrior of the Hizen Nabeshima clan, he went by the name Nisshin. He came to Matsuura in Hizen Province (Matsuura City, Nagasaki Prefecture) during the Keicho and Genna periods (1596-1624) and became a pupil of Goroshichi Takahara under the guidance of a fellow countryman named Zenbei, and together they moved to Ariwatani Kawanai (Arita Town, Nishimatsuura County, Saga Prefecture) where they engaged in celadon firing. He died on October 5, 1654. During this period, the Soeda family had nine generations of descendants, and from the end of the Genna period (1615-1244) to the beginning of the Meiji era (1868-1912), they perfected the unique Okawachi ware, which could be called the Nabeshima style, over a period of more than 240 years. According to the genealogy, Kizaemon Kiyosada II died in September 1667, Tojiro Kiyonaga III died in March 1678, Kizaemon Masanobu IV died in November 1724, Magosaburo Masaharu V died in August 1768, Gontaro Masaaki VI died in May 1770, Magosaburo Masayoshi VII died in May 1771, and Magosaburo Masayoshi VII died in September 1772. The generations up to Magosaburo Masayoshi VII all worked as potters, but when Masayoshi VII took over the pottery business, the Sarayama government office was newly established and the Okawachi Kiln came under the jurisdiction of the government office, and he was recalled to the Saga domain. The Okawachi Kiln was under the jurisdiction of the new Sarayama government office established under Masayoshi. (Shinichi Terauchi, “Soeda Family Genealogy”)
