Leaving Japan then returning

Hello


Asking for a friend (UK national currently living in Japan) who is looking to return to the UK for personal reasons.

He has a specialist in humanities visa (valid until early next year) and is looking to return to the Uk for a month or so. He has yet to be vaccinated and will most likely not be before travel. So obviously will need to quarantine on arrival in the UK.

But what I am asking here, is will he be-able to return to Japan?

I have had a quick look online but couldn�ft seem to work it all out with all the different visas etc.

From what I gather he might have to quarantine for 14 days if he is allowed back in? But on one website it stated something along the lines that if you stay in a country for over 14 days you might not be able to re enter. I�fm very confused!
Can someone please help! Obviously I assume this would all be a lot easier if he was vaccinated but alas he isn�ft yet.

Also what are the chances of the rules changing while he is out of the country?

Also I gather if he can return that he might have to rent a phone at the airport so he can be contacted. Currently he only uses a data SIM card so doesn�ft have an actual phone number. Does anyone know how much this will cost?

Any help will be much appreciated.

Thank you

Ben

Would it not be a better idea to contact the immigration ministry directly?

My understanding is that all residents of Japan can re-enter Japan, and that the vaccinated will have to quarantine for 10 days while the non-vaccinated will have to quarantine for 14 days. I believe that people from most countries can do their quarantine at home, but if you arrive from one of selected countries, you have to spend your first three days at a designated quarantine location, and that the UK is currently one among those selected countries.

Currently he only uses a data SIM card so doesn�ft have an actual phone number.
Cheapest would be to get an 050 number - say from Skype. I had those in different countries before and the one I had for Japan for a project cost me something like 2000 yen for a year (never used it, but it wasn't expensive).
Alternatively, get a cheap phone plan - my cell phone costs me 999 yen/month.
