At the core of YKK AP's business activities are the "YKK Philosophy," the "Management Principle," and the "Purpose." These ideals form the basis of employees' conduct and management decisions.
Taking these to heart, YKK AP will continue to take on the challenges presented by this new era, and aim to be a company that builds a better society.

As an important member of society, a company survives through coexistence. When the benefits are shared, the value of the company's existence will be recognized by society. When pursuing his business, YKK's founder, Tadao Yoshida was most concerned with that aspect, and would find 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, making it possible to contribute to society. This way of thinking is referred to as the CYCLE OF GOODNESS^®, and has always served as the foundation of our business activities. We have inherited this way of thinking and have established this as the YKK Philosophy.

The YKK Group's Management Principle, based on the spirit of the CYCLE OF GOODNESS^®, is "YKK seeks corporate value of higher significance." We aspire to become a company that is appreciated by our customers, valued by society, and where all employees are able to work with pride and pleasure. As a means to achieve this, we will enhance the quality of our products, technology, and management. In putting these into practice, we always place Fairness at the foundation of all our business activities. This Management Principle was formulated in 1994 by Tadahiro Yoshida, then President of YKK and YKK AP.

YKK AP's Purpose expresses our desire to be a company that contributes to society through our products and services. That is, to continue to meet the desires of our customers and business partners with the Architectural Products that form the structural elements of houses and buildings. In doing so, we continue to be a company that contributes to customers, business partners, and society at large.
While carrying on the ideals embodied in the company name "YKK AP," we aspire to remain an integral and essential part of this ever-changing society.

Through "Architectural Products," that is, industrial products for architecture such as windows, doors, curtain walls, and exterior products, we will continue to pursue technology and beauty in architecture. To use our products to contribute to energy conservation and CO₂ reduction, to contribute to comfortable living, and to build a better society as a whole by accumulating each small happiness one by one. YKK AP's Purpose is the embodiment of these ideas.
Our hope is that, by connecting people, the planet, and the future, we can work to create a better society.

In order to support sustainable business growth, YKK AP is working to create an environment in which employees are conscious of the YKK Philosophy, Management Principle, and Purpose in their daily work. One example of this is the "Talking Sessions," where employees at each location and division share their own practices and ideas. These meetings are held annually to create opportunities for every employee to think about the connection between their work and the YKK Philosophy, Management Principle, and Purpose, and to help these ideals become widely understood and embraced. Through communication based on exchange and dialogue, we aim to foster a sense of unity in each division and the company as a whole, as well as to develop the people and culture that will support sustainable growth. In FY2024, talking sessions were held at all of the approximately 2,000 divisions in Japan (Sales, Development, Technology, Manufacturing, and Administrative).

Ever since YKK's founding, the spiritual pillar of all YKK Group business activities has been the CYCLE OF GOODNESS^® YKK Philosophy, which embodies our belief that no one prospers without rendering benefit to others.
An enterprise is an important member of society, and as such it must coexist with other elements of society. The value of its existence will be recognized by the benefits it shares with society. In pursuing our business, YKK has devoted great attention to the way in which we can realize such mutual prosperity–that this can be best achieved by the continual creation of new value through innovative ideas and inventions. This would result in business expansion for the YKK Group, which in turn would bring prosperity to consumers and trading partners, and thus benefit all society.
Every YKK company based in approximately 70 countries and regions around the world shares the CYCLE OF GOODNESS^® Philosophy and the Management Principle "YKK seeks corporate value of higher significance." "Fairness" is the standard on which we base our conduct.

We do not take lightly our responsibilities as a good corporate citizen, not only toward society but also in the execution of fair business management. Significant changes are taking place in the environments that surround the YKK Group. Whether in Japan or abroad, it is our duty to respect diversity—of cultures, customs, and viewpoints—and play a role in the development of society through our business operations. The YKK Group is committed to helping build a more sustainable society through its main businesses.
The YKK Group promotes initiatives aimed at realization of a sustainable society through its core businesses by implementation of the YKK Philosophy ― CYCLE OF GOODNESS^® and its Management Principle "YKK seeks corporate value of higher significance."

To drive YKK APʼs sustained growth, we have conducted a review of our Materiality (Priority Issues) in FY2024 based on our Purpose. We have established a system for promoting Materiality and are further advancing specific initiatives by setting KPIs.

In line with the start of our 7th Mid-Term Management Plan (FY2025-2028), we reviewed our Materiality (Priority Issues). To promote these initiatives, we have established promotion departments for each Materiality Issue, and are working to achieve our goals through the implementation of our 7th Mid-Term Management Plan.

Furthermore, in the 6th Mid-Term Management Plan (FY2021–FY2024), we advanced each initiative through practical implementation.
