Noritake Co., Limited, commonly known as "Noritake," is a tableware and technology company headquartered in Nagoya, Aichi Prefecture, Japan. In 1904, key members of the company created the Nippon Toki Kaisha, Ltd. in Japan. Nippon Toki wares were mostly aimed at the European Market. This forerunner of the modern Noritake Company was founded in the village of Noritake, a small suburb near Nagoya, Japan. Most of the company’s early wares carried one of the various “Nippon” back stamps to indicate its country of origin when exported to Western markets.
