I think I agree with you. The key thing to note is the speed at which new technologies are adopted, rather than the question of adopting as private vs public. I suspect someone with the right connections and resources could invest in the Yen, then strategize to put Japan as a frontrunner for electric car technologies (thus revitalizing its economy) and make a lot of money.

That sounds like a multi billion dollar investment, and Japanese companies do a great job of building electric cars for the export market already.
