- MESSAGE FROM THE MANAGEMENT –
Reliable Technology Is Our Concept !
Toho Seiko Co., Ltd. was established in 1957 in Toyooka City, the central city of Tajima, Hyogo, where Japanese white storks are flying around in the rich and plentiful nature. As an expert on precision springs, we continuously receive good reviews for our technology and its quality from customers in various industries including optical equipment, information communication equipment, industrial equipment, automobiles, home appliances, and electronic parts.
Today, we have entered a new business field: the medical equipment industry. By utilizing the production equipment and rationalization equipment developed within our own company, we are able to expand into newer and more complex fields within multiple industries. We will continue to challenge new fields to meet your needs.
We established the factories in Shenzhen, China (1991) as well as Shanghai (2003). Starting from China and South-East Asia, we have developed the “TOHO SEIKO” network to provide precision springs to customers all over the world.
Our original company’s motto was “Integrity, Creativity, Action before words.” Our current motto, “Contribute to The World with Reliable Technology,” possesses the same spirit has the original. It inspires all operations within our company with the belief that through manufacturing, we will contribute to the development of local industry, the nation, and the world.
