Leveraging state-of-the-art technologies, our original production systems support advanced manufacturing that responds to the demands of the times.

The history of our company started in 1918 with the manufacturing of terminals in the Shimo-Osaki district of Tokyo.
Since then, we have pursued manufacturing that fits with the times in response to customer demands.
We have explored part-manufacturing technologies by means of our original production system, in which our in-house stamping die, molding die, and automatic assembly machines are combined.
Now we are manufacturing various electronic parts including switches and connectors that are to be incorporated in electronic devices such as cellular phones, digital home appliances, and PCs.

While preserving inherited technologies, we will keep taking on the challenges of new manufacturing and offer advanced and high-quality products and services that only UGM can produce.
