Message from the President

Thank you for visiting the website of Koto Electric Co., Ltd.
We have been a manufacturer and distributor of various lamps and hermetic seals since our inception in 1947.

For lighting solutions, we supply not only lamps but also lighting systems and power supply devices. Our aim is to become a system supplier to the world market.
Hermetic seals division manufactures hermetic seals for quartz oscillator packages and develop products utilizing our glass to metal sealing technology.
In addition to Japan operation, in 2005, Koto Electric opened a manufacturing and sales facility in Tangshan City, Hebei Province, China. This was in order to reduce manufacturing costs and increase the sales in Chinese market. Now we are expanding our market share by improving our price competitiveness. Sales of studio lighting along with fishing lighting have continued to increase in the Chinese market.

As a result of focusing on advanced plating technology, we have received numerous inquiries from companies including device and glass manufacturers regarding our
i) Resin plating technology which uses ultraviolet (UV) for the first time in the world
ii) UV irradiation systems
iii) Direct copper plating on thin glass sheet
for application to printed circuit boards, communication components, communication antennas, optical sensors and touch panels.

With "Explore worldwide demand with brand new idea" as our basic principle, we will strive to expand our business aiming to become a company with annual sales of 10 billion yen.
