Did you mean discipline in the way Foucault uses it?
These economies were heavily planned after the second world war to prevent shortages. It is this sort of planning that lead to enough international cooperation so that it evolved into the EU.
At that time Sony got started with its long line of success with consumer goods by selling transistorized radios. In so far as the planning gave Japan a stable economy, it helped Sony. But central planning had nothing whatsoever to do with Sony's or Toyota's success. One thing that helped Toyota, by the way, was the export quotas to the US. Since they were one of the chosen companies, they enjoyed maximum profits on their US sales, which they could use to offset the intense competition they were getting in their domestic market. This is why Toyota survives as Toyota, but Mitsubishi (prevented from buying Chrysler when Iacocca ran it) is now part of Daimler-Chrysler.
