Planar Magnetic headphones. Can't go back.

Not as far as I'm aware.

There is the GFCI in the switch box, but yeah, both gfci+grounded would be preferable.

Yup. Japan also has grounded outlets, though, although they are comparatively rarer.

Japan also accepts bank transfer for online payments. So you don't even need to leave your house.

No thanks. It's not for me.

What are the alternatives to Visa/Mastercard?

Absolutely. I'd switch to other payment methods that aren't those, if you can.

Good job, EU. I hope the rest of the world takes note.

Rules for thee...
