AFAIK, Japanese receptacles are NEMA 1-15,
but an earth is available. I don't know what
is in the walls or service panels.
They use 100V, 50 or 60Hz, depending on location.
Other than minor differences, Canada and
the USA use the same wiring.
For instance, all along, Canada has used
4 prong fittings for range/dryer connections
(the USA has adopted that in the last 5 years). The NM cable here has no paper inside it (at least new stuff). Kitchen
receptacles are to by wired on shared neutral
15A circuits, in the USA 20A single pole circuits, with GFCI on islands or near sinks.
FPE Stab-Lock panels and accessories are
still sold and used, and I guess approved.
