One of the most interesting things about Japanese business, is how much was built by New Dealers who came over in the occupation. Americans rebuilt the giant conglomerates, we reinforced the idea of life time employment (salarymen were very consciously modeled on American professionals of the 1950s and 1960s, then made Japanese), we insisted on tight government-corporation intervention in the economy to encourage growth and stability. People often try to make it sound like this ancient relic of Japanese culture, and it's really not. It's a weird fusion of Japanese thought and new Dealer technocratism, left to develop on it's own for decades.
