I have worked in several office environments in Japan where coworkers have frequently napped at their desks.

Right, but as the article points out, that's socially different. Working at your desk and succumbing to sleep is tolerated whereas stretching out on the couch with the intent to sleep is not.

I have also observed this behaviour, especially from higher ranking employees.

Saw this often at the chaebol I worked for -- I think Korean work / nap culture is similar.
