High quality, constant precision and
lasting security

Value-based corporate philosophy

The YKK Group is shaped by the Cycle of Goodness and the monozukuri philosophy. Monozukuri describes the art and craft of making things, guided by the pursuit of the continuous improvement both of the manufactured product and of the production processes and systems.

The Cycle of Goodness

Initiated by YKK company founder Tadao Yoshida, the “Cycle of Goodness” describes the corporate philosophy of shared benefits. It is based on the conviction that no one can be successful without allowing others to share in their success. In this spirit, YKK STOCKO contributes to the growth of its customers with its high-quality products and services.

In accordance with the Cycle of Goodness, YKK President Tadahiro Yoshida coined the management principle that YKK is seeking corporate value of higher significance. This is based on the claim that we only produce perfect and high-quality products from which the end product can benefit.

Fair and equitable cooperation

Behind these management principles is the vision of a fair and equitable cooperation. This applies to all the business activities within the YKK GROUP, which are focused on a single objective: to provide all our customers with the highest level of quality and service.

The basic management principles of all the companies in the YKK GROUP also include contributing to the growth of a sustainable society.
