Company founded in June 1946 in Suwa by the brothers Masahico and Rokuichi Yamada.

"Sankyo Seiki Mfg Co Ltd was incorporated in June 1946 as a music box manufacturer. Initially, craftsmen had made music boxes by hand, but in 1950, four years after incorporation, Sankyo Seiki established the world's first mass production system of music boxes by mechanization. It has produced a variety of music boxes, from high end products to products for popular use, and soon climbed to become the largest music box manufacturer in the world. In the latter half of the 1950's, when Japan entered the age of high economic growth, the Company started production of industrial equipment on the basis of precision technology, developed as a result of its music box production. In 1957, it started production of 8mm movie cameras and projectors and, in 1959, it started production of driving parts, including micro motors and time switches, which were embedded in home electric appliances. As a result, the Company accomplished a great transformation to a precision equipment manufacturer from a music box manufacturer. Thereafter, along with the advancement of electronics technologies, it has expanded its product line-up to home electric appliances and housing equipment, information device peripherals and industrial equipment. In response to rapidly advancing digital technologies, it has also developed new equipment materials and products as core elements of optical and magnetic basic technology, which is the basic element of digital technologies."
