Antique Morimura Bros. / Noritake / Nippon Platter
In 1876, Ichizaemon Morimura VI and his brother Toyo founded Morimura Gumi with the intent of establishing overseas trading by a Japanese company. By 1878, Toyo had established a business in New York selling Japanese antiques and other goods, including pottery. The company was renamed Morimura Brothers in 1881. By the 1890s, the company had shifted from retail to wholesale operations and started working on design improvements for the pottery and porcelain ware, which had become one third of its business. By 1899, all of the pottery and porcelain decorating factories in Tokyo and Kyoto had been consolidated in Nagoya, and the company started research on creating European style hard white porcelain in Japan.
A new factory was built in Noritake, near Nagoya. In 1914 the company succeeded in creating their first Western style dinner set, called “Sedan”, to compete with European porcelain companies.
Today, many collectors agree that the best examples of “Nippon-era” (1891–1921) hand painted porcelain carry a back stamp used by “Noritake” during the Nippon era. (I copied this information from Wikipedia.)
