So I'm curious. I live in Japan and have a Japanese number. I have a USA number via Google Fi. I get several spam calls on the USA number but zero on the Japan number. Any idea why? It it just luck? It is scammers don't target Japan? Is it some technical difference that makes it harder/impossible/costly in Japan? Is it an enforcement issue? Also what happened / is happening with https://en.wikipedia.org/wiki/STIR/SHAKEN https://en.wikipedia.org/wiki/STIR/SHAKEN ? Will it solve the issue?

A quick look at my voip carrier says calls to us are 1 cent, and calls to Japan land lines are about 2.5 cents, and Japan mobile is 10 cents. They've generally got pretty good pricing; with volume you can get better, but this is a good place to start. So call cost is going to be a lot more. Then you've got to find voice talent. You can find English voice talent all over the globe, Japanese voice talent is harder to find and probably costs more. STIR/SHAKEN will likely help somewhat. It should make it easier to track down accounts of callers, but we'll have to see if enforcement becomes effective, or if actionable complaints make enough of a difference. I don't think telephone companies regular record enough metadata for effective enforcement at the moment, and there isn't a reasonable way to report abuse, so most people just shrug and pick up less calls; we really need a useful reporting mechanism (dial * something after you get a spam call should work IMHO; but that's not me doing the work to correlate reports and what not)
