The business of YKK AP

Residential AP Business

Comfortable living starts with good windows and doors.

We provide solutions for comfortable living in the form of our APW brand windows (Japan's first window brand), entrance doors, and window-related products. We're improving the safety and insulation performance of windows and doors, aimed at building a society that is good for both homes and people.
*We call our business "AP Business."
This means that we deal in finished architectural products, as opposed to "building material business," which would also deal with raw materials.
