Japanese screw up too - they are human after all .
I read an story recently about a train line that allowed one of its trains to leave something like 30 *seconds* before it was scheduled to leave. The company issued a specific apology for such a grievous error. I kid you not!
Also,years ago there was a horrible accident in which a Japan Airlines 747 crashed killing something like 500 people. Not long after that at least one airline official (and I think it was more than one) committed suicide. IIRC the final report said that it was Boeing's fault for having improperly repaired damage that had happened to the plane years earlier.
