Our View of Sustainability: The Cycle of Goodness®

YKK is constantly pursuing the creation of a sustainable society through all our business undertakings. At the core of all our corporate activities is the philosophy of YKK founder Tadao Yoshida, the Cycle of Goodness®. The idea of the Cycle of Goodness® that ‘no one prospers without rendering benefit to others’ clearly expresses the YKK Group’s corporate spirit of continuing to prosper together with society, customers, related industries, and employees, and we consider it to be a concept that fosters sustainability. Under the Cycle of Goodness®, YKK will address the essence of sustainability through our business practices and products and will continue to tackle environmental challenges in order to remain a socially upstanding company.

YKK is constantly contributing to a sustainable society. The foundation of our corporate activities is the Cycle of Goodness® philosophy of YKK founder Tadao Yoshida. This philosophy clearly expresses YKK’s desire to prosper together with society, customers, related industries, and employees, and is a concept that is highly compatible with sustainability. The founder repeatedly conveyed the essence of this corporate philosophy to employees, speaking of it in various ways. It even continues to remain at the center of company activities to this day, more than 80 years later.

YKK sustainability vision 2050

In October 2020, we formulated the YKK Sustainability Vision 2050, which sets numerical targets for the Fastening Business from the 2019 YKK Group Environmental Vision 2050. As part of this, we have categorized our objectives under five themes: climate change, material resources, water resources, chemical management, and respect people, and are carrying out activities that will contribute to achievement of the 2030 SDGs as well as carbon neutrality by 2050.

Business is like building a bridge

I don’t think that a business will prosper unless it is both profitable and also contributes to the world and is useful to human society. Nothing brings more happiness than when we can contribute to the local industry and the local economy, thereby enriching the lives of local people. YKK’s “bridges” that bring abundant civilization to developing countries and new affluence to developed countries will continue in the future.

Manufacturing like clear spring water

Like a wonderful fountain, it bubbles forth, rich and authentic. This is true abundance. The important thing is not to waste valuable resources. Then it will be a great product.

If we make use of our ingenuity, even our waste can be a great resource

The first thing we should do is think about how to better deal with waste from our own neighborhoods and implement those ideas together. If we continue digging for underground resources, cutting down trees, catching fish, and increasing oceans where fish can’t live as we are doing now, it will mean the destruction of humanity.

The strength of the forest is greater than the trees

Some trees are thick with experience and age, others are young and thin. There are tall trees and short trees. We work well together, not under the control of anyone, using our strengths and abilities according to our individuality.
