HISTORY

founded the original spring factory in Edogawa-ku, Tokyo Japan in 1930. The company incorporated under the name KATO SPRING WORKS CO., LTD. in 1946. At that time, the main products of KATO SPRING were springs for weighing scales and the domestic market share of Kato in this application reached approximately 90%.

In 1952, an automatic coiling machine was acquired and this greatly reduced production costs for mass production orders. From this point in time, KATO SPRING started to be known for and specialized in the production of precision wire springs for optical instrument, electric equipment and many other high volume markets.

Mr. Kiyoshi Kato, who is a son of Inokichi Kato, became the president of the company in 1962. The building of a headquarters factory having four floors (located in Tokyo) was completed in 1963 and KATO SPRING was officially listed on the 2nd Section Tokyo Stock Exchange in 1964.

In 1966, a new challenge arose to produce precision flat spring in addition to the traditional wire springs so this new ability was added. Our success in flat springs engineering was instrumental in our growth during that time period.

In 1966, KATO SPRING established the first oversea sales subsidiary KATO SPRING USA in
Long Beach, California, which was a long time dream of Kiyoshi Kato. In 1985 KATO SPRING USA began a US production concern in Huntington Beach, California and the name changed to KATO SPRING OF CALIFORNIA.

During the 1970’s and 80’s, Yuichi Kato, who is a son of Kiyoshi Kato, joined KATO SPRING and took an active part in the globalization of the company, including launching the factory in Singapore in 1978, which remains today as our Global technical center.

As globalization continued, a large production factory having 183 members in Kashiwazaki was founded in 1976. The variety of products was expanded. In 1986, an additional factory located in Fukushima was opened for the fast growing computer industry producing components for floppy disks. In 1988, a production factory was established in UK, giving Kato European reach.
