Sorry for posting this slightly off-Decware question.
I've lived in Japan for decades. The mains power is 100V (and oddly, 50Hz from Tokyo north, the other half of the country is 60Hz).
I've never seen residential wiring that is grounded, even in new buildings. They just don't do it here. If you want grounded outlets you have to have someone come in and run a huge wire out the wall of your house and into the ground. While they're installing it, they'll ask you what in the world you need it for -- are you going to mine bitcoin or something?
In fact, my wife's father (unfortunately no longer around) was an electrician. I asked him about this once and his reply was more or less, "Sure, if you think you need it. Do you really?"
I could my landlord to put something in, I guess, but my equipment isn't in a convenient location to run a wire outside. I googled "portable electrical ground," hoping I could equipment-buy my way out, but got nothing.
I have surge protectors on all my equipment. Do I really need everything grounded or is this something non-Japanese manufacturers say to cover themselves? For example, I just bought a big refrigerator -- it came with a regular old 2-prong plug. Makes me wonder. Maybe the voltage is too low to make it necessary?
