The issue in Japan that hydrogen seems to have an advantage is the storing of that energy and the time/space required to to transfer that stored energy (be it hydrogen or electrical energy) into a vehicle.

Things like "most homes in Japan don't have a convenient place to put a DC charger or external electrical outlets" and "the larger scale Tesla charging places don't fit in existing infrastructure."

This sort of home parking places (https://www.google.com/maps/@35.6772271,139.70988,66626m/dat... ) don't match the American style "room enough for a car and space on the side with power for lights and a garage door opener.

On the flip side, a h2 station in Japan has about the same footprint as a regular gas station ( https://youtu.be/UHft5Lbf2Ho ). That doesn't present a "it takes 40 minutes to get an 80% charge at a dedicated super charger station" but rather something closer to the "fill up the tank" of ICE cars.

If this switches to the US, the H2 infrastructure compared to electrical infrastructure (Note: Japan is kind of weird there too - https://en.wikipedia.org/wiki/Electricity_sector_in_Japan#Tr... - "Electricity transmission in Japan is unusual because the country is divided for historical reasons into two regions each running at a different mains frequency. Eastern Japan has 50 Hz networks while western Japan has 60 Hz networks."), population density, and the ability to charge at home makes the idea of a H2 based vehicle throughly impractical.
