About YKK AP

We Build a Better Society Through Architectural Products.



"No one prospers without rendering benefit to others."
YKK's Founder, Tadao Yoshida named this philosophy the "Cycle of Goodness" and made it central to all
business activities as he built the YKK Group into what it is today.
Our mission at YKK AP is to carry on this philosophy and provide our customers with windows
and other architectural products to lead healthy and comfortable lifestyles.
Going forward, we will continue refining the technical skills we have accumulated over the years to
offer products that will bring happiness to people around the world.

YKK Group Management Structure

In FY 2021, the YKK Group merged the YKK Machinery & Engineering Group, which had been responsible for manufacturing dedicated machines and developing equipment for the YKK Group, into the fastening business and AP business, respectively. Furthermore, YKK AP will switch from a six-region global management structure for the entire YKK Group to a consolidated management system in which Japan's YKK AP manages YKK AP Group companies around the world to sustainably enhance business competitiveness. In line with such reorganization, YKK AP's capital has changed from 10 billion yen to 14 billion yen. The YKK Group will strive for further growth as a corporate group that shares the YKK Philosophy and Management Principle.
