Will research this more, maybe I read BS  :).

Japan has 220V mains, just like the US has 220V mains. Two lots of 110V, with a 180 degree phase shift.

US is 240V, 120V x2, and Japan is 200V, 100V x2.

DavidAlfa:
Yeah, I swear I found this very recently searching for something related.
But it seems I mixed 3 different memories and made an entirely new thing after a bad sleeping night :-DD
Ground_Loop:
Yea, but can your outlets do this?

I say that worldwide everyone should switch to 30 volts DC.  Best and safest current for all purposes.

That would work well with the infamous 3 kW British tea kettles.
100 A requires, perhaps, AWG 0 = 8.25 mm diam = 53.5 mm2 wire.
