oh yes they really reallly really value their personal space / privacy. It was even discussed how far are we going to protect the personal space of each person. There was a case in the news last year, an old man living alone, was found dead cause he slip in his room and he was unconscious , no one bother to check on him when he did not go out because they thought he needed some privacy.. after a couple of days, the kanrinin finally decided to check on him and found him dead.
Then we they were hit by the spyware winny, there was a big issue on protection of personal information. All personal information must not be disclosed, somehow it was blown out of proportion that somehow I find it really amusing
