In 1881, Kibataro Oki, a former engineer of the Telegraph Bureau, founded Meikosha, the predecessor to OKI. The company developed a series of new products including a "microsound" device that worked on the same principle as the Edison telephone when Japanese people had little interest in electricity, let alone telephony. In other words, Meikosha, true to its enterprising spirit, contributed to the expansion of the telephone business in its early days.

Since then, the OKI Group has developed and offered technologies, products and services resolving various social challenges in many aspects through its over 130-year history. In recent years, the group has also promoted the improvement and enhancement of its management systems for the whole process from product development to distribution in order to respond appropriately to changes in the business environment such as the increasingly globalized economy and rapid progress toward an information society.

This section features four key challenges for the OKI Group in which our stakeholders as well as the public show an intense interest.
