I had a talk with my former Japanese boss at his son's wedding. They were also celebrating his apprenticeship offer at Toyota. In Japan getting a job at Toyota as a college graduate is very prestigious. Younger Japanese people today view career progression and workplace atmosphere much more than the older generation (who value job security and seniority more). Compared to other Zaibatsu, Toyota is run more like a western company with better career progression and flatter management structure. And although the working pace is very fast, people feel more motivated when they are actually productive (unlike traditional Japanese overtime culture where people are just twiddling their thumbs) That's why now 50% of Japan's engineering MS and PhDs choose TMC as their primary job choice. TMC attracts Japan's best talents. The job is hard but rewarding.
The opposite is happening at Nissan and to a lesser degree Honda. Under foreign management Nissan lost a lot of their talents who don't want oversight from someone from another culture. Both companies have to rely on the older generation engineers (those who developed the best Bubble Era cars) to develop high complexity products like GT-R and Civic Type-R. But these people have now retired and both companies could not develop any in-house technology for luxury or performance cars. When is the last time either Infiniti or Acura had a product that's up to date with competition? That's why Infiniti had to borrow engine from Mercedes and Acura had to shift all R&D to USA. To their credit HPD did all they could to salvage the NSX and TLX Type-S, they are after all just a small scale workshop not intended to build production cars. And if Honda just let Acura USA do their thing they would be in a better place. Another positive for Toyota is their hands-off approach to just let regional branch decide what products to make. That's how Americans get the great TRD trucks and IS500 FSP, we get LWB sedans and ultra-luxury minivans in China for example.
