Remember that China briefly embargoed Japan for rare earth metals in 2010, and Toyota launched the Mirai in 2014. My theory was that it was developed as a national fallback for Japan in case that embargo continued or got worse. Think 1930s Volkswagen. Anyone can comment on that?

Japan went heavy into hydrogen for a couple of decades ago. The only reason we are even talking about hydrogen passenger vehicles now is because Japan thought it was the future, they made a mistake.

I'm pointing out that the timeline of continuing funding it, to the point of a major model design and launch, and nationwide network of hydrogen stations, might well be linked to China's emergent REE dominance and that Japan doesn't have those raw materials.

(In some future decade/century, people might conclude that car dependency on fossil fuels, after electric from renewable became viable, was a mistake.)
