早く日本も、何とかして！
Dear Yoichi
We are pleased to share the latest international travel news announced by the UK government last night. From 4 am on 11 February, fully vaccinated travellers arriving into the UK will only need to provide a new and simplified version of a Passenger Locator Form (PLF). Testing will not be required.
With the combination of the UK’s successful vaccine and booster programme roll-out and previous Plan B measures, the UK government feels confident to now reduce the restrictions and go one step further to reopen the travel sector.
