Company information

We support everyone's "lifestyle" with pioneering technology and cultivated know-how!

Founded in 1950, Oi Electric has realized many developments, including the pocket bell (1963) and desktop calculators (1963). The challenge spirit of the engineers at that time has been passed down to the current engineers, and we will continue to contribute to the development of social and communication infrastructure. If you are thinking, "I need something more than a generic product," "developing this will be costly," or "is there a product like this?" we would appreciate your contact. After listening to your needs, we will propose products that match your requirements. Our strength lies in developing high-quality products that can only be made through domestic production.
