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.)
