Still, if there's one thing Japanese firms have distinguished themselves by, ever since the 1950s, at least, it's planning with a 25-year time horizon, whereas the average Western manufacturer seems to think 5 years is a lifetime (and so it is for senior executives, who are looking to make good numbers and get out ahead of the consequences, with a fat bonus).
