What does the R stand for at the end of 14-50R

The R in 14-50R stands for receptacle.

Can these be used in japan tokyo 50hz 200v 50a?

No, These items are rated for the North American market and rated at 125/250 VAC. Using these devices at a different voltage can shorten the life of the device and be unsafe. Best Regards, TopGreener Inc.

I'd planned to run 6-gauge wire to this (for 50 amps), but the receptacle has stamped on it "wire size awg #8". is it still ok to run #6 to it?

Hello, For this outlet, it accepts 8, 6, and 4 gauge Copper Wires (AWG), Neutral wire is required and can be applicable to 125V or 250V applications and up to 50 Amps. Best, Top Greener Inc.

Looks like people use this for electric range (240 volts) too. Is this receptacle safe for electric ranges? or this is for electric cars and RVs?

Most 14-50 sockets are used for ranges and stoves, but they are not designed for repeated plugging and unplugging. This one is a popular choice for EV charging, since the manufacturer claims it is designed for that use.
