FYI, anti-vaxxers are generally not well-received around here, or anywhere, as it should be. And the point of requiring visiting foreigners to be vaccinated was never about preventing them from getting infected or even spreading it, but reducing the chances that said foreign traveler--should he or she get infected while in Japan--will not become seriously ill and burden the healthcare system. But let me tell you, homeboy, I am so, SO glad I will have the ability to come back and visit before unrestricted tourism resumes all the classless assholes like you are allowed back in (and I hope it's not until 2025). There's a reason the majority of Japanese citizens (and even resident expats, ask around TAG) don't want you in the country and I certainly don't blame them.
