Kibataro Oki died in 1906, aged 58. After establishing Meikosha in 1881, Kiabataro dedicated his entire life to the manufacture of telegraph and telephone devices. He had no particular hobbies, nor did he indulge in any luxuries. His simple interest was the growth of OKI and Co., and he witnessed the company's success before passing away.
OKI and Co Ltd was established and all of OKI and Co.'s assets were transferred there. The articles of incorporation of the new company listed its capital at 600,000 yen. The company had six members with unlimited responsibility - Kibataro Oki Jnr, Take Oki, Umakichi Oki, Eitaro Kinoshita, Kiyoshi Itoh and Totaro Katoh. These were either members of the family or long time employees from the Meikosha days.
A new production facility in the Tamachi section of Tokyo was constructed. The existing factory in Kyobashi section then came to specialize in wire manufacture, and began processing ebonite and manufacturing rubber-covered wire.
