Today’s Word is: Chack (チャック)
In Japan, zippers are called “jippā,” “fasunā,” or “chack.”
Jippā (zipper) and fasunā (fastener) are obviously derived from English, but what’s chack (チャック)?
Chack is actually a made-up word coined by a zipper manufacturing company in Omichi as a trademark. It’s derived from Japanese word kinchaku (巾着), meaning drawstring bag. The trademark was registered in 1927, and zippers sold under the trademark “chack” were received very well by public.
Today, zipper, fastener, and chack are used interchangeably in Japanese.
