YDS Company Profile

Background

For over 60 years, YDS has been manufacturing various products with sturdy spirit and cordial gratitude cultivated among so many relationships, since it was established in Yokohama in November 1940, as a manufacturer for telecommunications.

In 1974, a main plant was built in Omi, facing to the beautiful blue Japan Sea, where old stratum and new had met and a range of mountains lie magnificently, which are themselves severe environment, but at the same time they can give us splendid scenery all the year round since ancient time. With a good relationship within people and community, we hope we can devote to society seeking more earth friendly manufacturing methods. It is the greatest joy that we can serve progressing science technology through even our tiny products.

And we are very happy to have the flexibility for rapidly changing markets with a daily effort and high technology accumulated throughout a long history.

We are continuously trying to advance step by step in this field, supporting a more comfortable life in an ISO14001 certified operation and considering the environment from such a beautiful place.
