The most valuable asset for the company is its people.
In 1940, at the place called “Saginomiya” in Nakano, Tokyo, the founding president of our company, Shigeru Nishimi, established "Bellows Research Institute". This is the beginning of Saginomiya's history. In 1948, SAGINOMIYA SEISAKUSHO, INC. was founded and started development and production of automatic controls on a full scale.
As a former educator, Shigeru Nishimi became a business person who advocated that the most valuable treasures of a company are its employees working together. With this idea, he built a company culture that nurtures and treasures its people. Since his inauguration, our company has maintained the corporate philosophy of “Creation of happiness for all employees and all people” along with our business motto “When alone, care for yourself. When with others, care for others. Always act for somebody else”. We still continue unstinted efforts in order to accustom employees to these philosophies.
Creating new values and offering them to others.
We started from bellows application products and have developed as a leading company in the automatic controls business. We have been expanding widely across many industrial fields, such as cooling, refrigeration, air conditioning, hot water supply heating, power plants, automobiles, trains, ships, medical equipment, semiconductors, and etc. In our test systems business, which began in 1964, the driving simulator DiM, an indispensable tool for Model-Based Design (MBD), has been highly acclaimed by both domestic and international manufacturers. Furthermore, we are creating new value through research and development of MEMS technology, which supports the IoT network society.
Fulfilling our responsibilities as a manufacturer towards a sustainable society.
Our basic management policy is to "Offer environment-friendly products and contribute to global society."
Offering products and technologies adaptable to the ever-changing needs of the times, markets, and customers, we thereby support "safety, security, comfort in your lives," "environmental conservation," and "sustainable society." We are committed to compliance, risk management, and environmental initiatives as a corporation. Additionally, as part of our social contribution efforts, we focus on human resource development and community activities.
