Now the fact that this man passed away while at work isn't the problem:

Tokyo - A Toyota employee in Japan died of overwork after logging more than 106 hours of overtime in a month, a judge ruled on Friday, reversing a
ministry's earlier decision not to pay compensation to his widow.
The Toyota Labour Standards Inspection office, a local branch of Japan's labour ministry,
refused to pay the widow the usual compensation for a
spouse's work-related death, saying the man had only logged 45 hours of overtime in the month before he died, Japanese media reported.

The problem, for me, is that he died on the job and Toyota don't want to compensate his wife because he didn't work as many hours according to them.
BUT, the fact is, he died on the job. Come on Toyota, do the right thing. He didn't die in his sleep, he died at work on Toyota premises.
Perhaps their argument is "tough, he died, there is someone in the Japanese population of 127,433,494 that can take over."
