Who we are

HQ : Nagaokakyo, Kyoto
Established : 1948
Employees : 280

We are an international pump manufacturer celebrating our 70th anniversary. We manufacture pump products that boast an overwhelming share of the market and are used in fields such as agriculture, civil engineering, and industry.

Since its founding in 1948, KOSHIN started out manufacturing general machinery, and as a manufacturer “dedicated to pumps”, we have accumulated trust, experience and achievements by providing a wide range of products and services.
As a specialist in pumps, which are indispensable for transporting liquids and gases, we have been supporting social infrastructure and everyday life of people.
Our history is defined by “innovation and challenge”. We have been contributing to the development of society and the improvement of the daily lives of people through our business, while staying close to the frontlines of people’s lives, with the unchanging desire to deliver products and services that are better for our customers. Now, we have grown into a global company with operations in approximately 160 countries and regions around the world.

Our vision

Everything we do is for our customers

KOSHIN has adhered to this philosophy since its founding.
We have always been committed to the development of products not only with the performance and quality, but with price that customers demand, based on feedback from users, rather than manufacturers’ self-satisfaction of developing superior products.
The first president, Jin’ichi Kohara, said, “The first thing I did in manufacturing was to go talk to machine wholesalers”. This attitude symbolizes the spirit of “everything we do is for the customer,” a philosophy that has been passed down since the company’s founding and will continue to be passed down in the future.

It is each and every one of our employees who carry out this philosophy.
“Only a company that takes good care of its employees can take good care of its customers”
As a company that has developed from a small factory, we at KOSHIN has been committed to respecting and nurturing our employees. That is the clear philosophy underlying our development from a small factory to what it is today.
“We’re working together to improve our own treatment by sharing our knowledge and making every effort to improve our efficiency.”
“Employees should not be sacrificed for the sake of the company’s profits.”
Such a feeling of caring for each and every employee has evolved into “a feeling of caring for each and every customer” over the long history of the company.
Our management policy expresses this spirit.
