First, the people checking the toilets are not the same people checking the engines. You were not in an un-safe situation in that respect,
Second, you should be very thankful that those 10 f/a's decided to stay on and work. They all go illegal at the same time, so the 4 that walked can't really be blamed but the 10 that worked allowed you to get to Shang Hai, otherwise you'd have most likely spent a fair amount of time in Tokyo waiting for a crew to be rounded up or being transferred to another airline.
