啱啱上左厚生勞動省睇
佢英文version係咁樣講
Those who are entering Japan on or after May 8, 2023, will not be required to present a valid vaccination certificate or pre-departure inspection certificate, as the category of COVID-19 will be changed to a Class V Infectious Disease under the Infectious Disease Control Law. However, please note that quarantine measures upon entry into Japan may be strengthened as necessary, if a new infectious disease outbreak occurs overseas.
咁係咪姐係可以唔使做 不過遲啲可能再有疫情爆發就會揸返緊
