Nagoya was the original center for cloisonne cloisonne [sic] enamel production in Japan. Ando Junbei (1876-1956) established one of five workshops-studios in the city. His workshop remains in operation today, the longest lasting of all the Japanese cloisonne companies. Ando Company artists specialize in a wireless technique that requires laborious layering of many coats of enamel to achieve the required thickness and color.
