When the company was founded in 1966, our main business was so-called "wage work," in which we received parts supplied by our customers, assembled TV units, stereo circuit boards, etc., and were paid for our labor in crafting and processing them. .

Then we began to produce and sell various pins including wrapping pins which are used in the PCB. It was the turning point to change our business from sub-contractor to manufacturer by ourselves.

Pins are the basic components of connectors, and through the development and accumulation of pin technology, we have established ourselves as one of the leading manufacturers of pins and pin headers in Japan, and finally started manufacturing and selling connectors, including sockets for power transistors. Today, our connectors are used in consumer and industrial equipment, mainly for automotive applications, all over the world..
