Dear Japan: This man is not being rude. He's having a work induced nervous breakdown. He requires medical and psychological help. Telling him that he just needs to keep it all bottled up inside and maintain appearances is not a healthy course of action. Thanks, and have a nice day.

The Japanese approach to everything is so crazy that I just assumed this was sincere. As I watched it, it never once occurred to me that it was a joke.
It's from the series "How to infuriate people".
You may remember the other one somewhere on here where after receiving someone's business card, the other businessman rips it up disdainfully in front of their face.
So yeah, it's meant to be satirical, as in the complete opposite of an etiquette video.
