Why zippers have YKK on them

The YKK stands for Yoshida Kogyo Kabushikikaisha (say that five times fast).  In 1934 Tadao Yoshida founded Yoshida Kogyo Kabushikikaisha (translated Yoshida Industries Limited).  This company is now the worlds foremost zipper manufacturer, making about 90% of all zippers in over 206 facilities in 52 countries.  In fact, they not only make the zippers, they also make the machines that make the zippers; no word on if they make the machines that make the parts that make up the machines that make the zippers. Their largest factory in Georgia makes over 7 million zippers per day.

In any event, Mr. Yoshida’s company zipped to number one by practicing the “Cycle of Goodness”, as he called it.  Namely, “No one prospers unless he renders benefit to others.”  Using this principle, he endeavored to create the best zippers out there that would hold up over long periods of time in the end product.  This in turn would benefit both the manufacturers who used his zippers and the end customer and because of these things benefit his company with higher repeat and referral sales, thus completing the “Cycle of Goodness”
