This speaks a lot about the quality of Japanese products and their quality
standards:

They're still laughing about this at IBM. Apparently the computer giant
decided to have some parts manufactured in Japan as a trial project. In the
specifications, they set out that they will only accept three defective
parts per 10,000.

When the delivery came in there was an accompanying letter. "We, Japanese
people, had a hard time understanding North American business practices. But
the three defective parts per 10,000 have been separately manufactured and
have been included in the consignment. Hope this pleases you."
