Japan is on the Uk Amber list.
What does it mean if a country is on the amber list? ... For amber countries, that means one pre-departure test, plus quarantine at home for 10 days upon return in England or Wales (for details on what the rules may be in Scotland it's best to look at the government website as they may differ).7 May 2021.
As I write this the Japanese government have not yet decided if crowds will be allowed to attend the Olympic games due to be held In just 50 days time. Japan is now in its 4th wave of the virus but still insist it is 100% committed to holding the games, though 70% of the Japanese people think it should be cancelled. I absolutely love watching the games but sadly it looks like a super spreader event to me.
