Look at the zipper on the pants you're wearing right now.

It should have "YKK" engraved on it in small letters.

Approximately 95% of zippers sold in Japan are YKK products.

Globally, 40% to 50% are YKK products.

The second-largest manufacturer has about 7%.

It's a product that anyone could make if they wanted to.

There are hundreds of manufacturers worldwide.

So why doesn't this gap close?

There's a secret that other companies can't imitate.

The "gap" that appears when the zipper is closed is intentionally left there.
The precision required for the mold is less than 1/100th of a millimeter. Finer than a human hair.
The zippers that close the pressurized suits of spacesuits are also made in Kurobe, Toyama Prefecture.
1.08 million counterfeit zipper heads were seized in China. The reason why they can still be detected.
A company started by three people after their previous employer went bankrupt and they took over the remaining inventory.

A company that makes parts costing a few tens of yen has sales of approximately 1 trillion yen. Tanaka, with 20 years of experience in overseas sales for a manufacturer, will share the impressive achievements of Japanese companies and the stories of their predecessors, as seen from around the world.
Please read to the end.
