Company Information

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

“It’s all for our customers”

KOSHIN has kept this one principle since its founding.
What does the customer who uses the product want instead of the manufacturer’s selfish assumption that he or she has developed an excellent product?
We have collected the feedback from the people in the workplace and made a thorough effort to create a product not only with the performance and quality of the product but also with the price that the customer demands.
The company’s first president, Jin’ichi Ohara, said, “The first thing I did in manufacturing was go talk to a machine wholesaler.” This philosophy has been handed down since the company was founded, and will continue to be carried on.

And it is each employee who carries out that philosophy.
“How can a company that doesn’t care about its employees care about its customers? “
KOSHIN is a company that has developed from a small factory.
Behind the progress we have made to date is a clear philosophy of nurturing and caring for people.
“We all share our wisdom, get creative to improve efficiency, and improve our own treatment. “
“We don’t believe the company can’t make money at the expense of its employees. “
This sense of caring for each and every employee has evolved over the years into a feeling of caring for each and every customer.
Such a spirit of “inside” to “outside” is expressed in management policies.
