The Tokyo offices had enormous rooms, with long rows of desks, arranged by section/department. The section manager's desk was at the end of each row. VPs, with billion-dollar budgets, had small, schoolteacher-style desks, in the corner of the room.
These enormous rooms, with hundreds of engineers, were quiet as a library. They had carpeting, people wore "office slippers," and there was very little chit-chat.
American open-plan offices, on the other hand, resemble flea markets. Loud, somewhat chaotic, and distracting as hell.
But the Japanese also have a culture that is attuned to open-plan offices. When we would bring them to the US, they would be uncomfortable with cubicles and offices.
I have found that "one-size-fits-all" solutions, don't really work, across cultural boundaries.
