In the 1940s, the company worked with Nihon Kogaku (now known as Nikon). In 1951 the company incorporated as a joint stock company and became known as Nittoh Kogaku K.K.. In 1996, the company launched an Indonesian production facility as a joint venture with Mitsui & Co., Ltd. and Astra Group, known as Pt. Adiwira Presisi Industri. In 2007 the company acquired Shoujoh Seiki Co., Ltd. and reorganized it into a subsidiary to boost production capabilities. In 2008, the company acquired full shares of the Indonesian factory, making it a wholly owned subsidiary.[1]

In 1950, it started to manufacture "Kominar" (コミナー) lenses used in a variety of cameras, as well as enlarging lenses. In 1961 the company began to manufacture complete cameras.[1]
