What are the requirements for getting into Japan now?

   I guess you have to be vaccinated with three shots: That's two vaccinations of the initial round and also a booster shot. So if you don't have that proof of vaccination, then you need to submit a pre-departure or pre-arrival PCR testing, that you need to take within 72 hours before you fly into Japan. Also, you still need to download the MySOS app, which basically smooths this process a bit for entry.
