Oil sector is lobbying for inefficient hydrogen cars to delay electrification

The Japanese electric grid is even worse than the one in the US.

Their grid is a mix of 60Hz and 50Hz networks because of weird historical reasons. It's also single-phase, which isn't the best for mass EV charging.

Compare that to, say, Finland where every single apartment and house has three-phase power. 3x16A or 3x32A usually. It's completely trivial to install a 11kW home charger for example, it's just running some cables and maybe adding a load balancer - all 100yo tech.

Most Japanese houses do not have parking garages or private parking spaces, so the ability to charge from home is irrelevant.

But in any case, single phase is fine for home charging and it's the default in many parts of the world. Three phase charging is a nice luxury, but far from a necessity.

In many Japanese cities you won't get a permit to buy a car unless you can prove you have a place to park it. Curbside parking isn't a thing.

So in those cases it really is irrelevant whether you can charge or not =)

Indeed. And it's not so difficult to make a rule that wherever car parks and parking spaces are built, chargers must also be provided.
