Japan to reopen to mass tourism in October
https://edition.cnn.com/travel/article/japan-reopening-border-tourists/index.html
If you live in 68 countries which are nominated into visa-free nations by Japan, you will be able to visit Japan only with passport and 3 times vaccination after October 11, 2022. Even if you are not fully vaccinated, certificate of negative is usable instead of vaccination.
I think that restriction of vaccination or certificate of Covid test should be lifted soon.
