They should include more countries for this to be a fair comparison.

Here in Japan you have to wait zero days to see the equivalent of a GP (a doctor of internal medicine is what would be considered the closest) unless it is a weekend or holiday. But even then, there are some clinics open on those days (they share the responsibility on a rotating basis).

You simply rock up and wait to be seen. Generally you won’t be waiting too long. Maybe 30 to 60 minutes. With pharmacies conveniently located next door, you’ll be in and out in no time when you’re feeling crook.
