As you can see, this is how the ground wire is grounded in Japan, and I don't know if there's anything wrong with it

Pretty crazy. In the USA the ground prong is always included with the plug.

It would be simpler if it was just included with the plug. In Europe, plugs are always designed so that ground connects first and disconnects last. "Schuko" plugs also have two contacts for earth, so earth connection is very robust and you cannot touch live prongs when inserting it. And you can be sure that earth is always connected when earthed appliance is used.

Too many things are secret. Only open information can really preserve old technology.

I like fluorescent and other conventional lighting and old electronic equipment. Today's things are not made to last.

Exactly the same for Switzerland's plugs and sockets. Additionally here you can not interchange live and neutral wire because of the position of the ground connector...

Ok. Polarized plugs are not very important on ac circuits, but in Finland older Edison screw base ceiling fixtures usually have special polarized plugs.

Right, but for example: In an Edison lamp holder, depending on it's design, it would be an advantage to keep Neutral on the outer contact and live on center contact.
