    The Cycle of Goodness

    When pursuing his business, YKK's founder, Tadao Yoshida, was most concerned finding a path leading to mutual prosperity. He believed that using ingenuity and inventiveness in business activities and constantly creating new value would lead to the prosperity of clients and business partners and make it possible to contribute to society. This type of thinking is referred to as the "Cycle of Goodness," and has always served as the foundation of our business activities.
