Imagine having permanent residency in a country, owning a home there and paying a mortgage on it, having a job and paying taxes, your kids were born in the country and go to school there and you’ve been paying health insurance and pension contributions. Yet, once you leave you are not allowed back into the country where you live. That is what Japan has been like for the last five months for any resident holding a non-Japanese passport. Meanwhile Japanese citizens where free to travel to Europe and come back to Japan. Also, Japanese citizens living in the EU, the US, Canada, Australia and New Zealand were able to travel to Japan and then return to their homes in the respective countries as long as they observed applicable quarantine rules.
Japan was the only G7 country treating permanent resident different from its citizens with regards to returning after a trip abroad. This policy led to criticism by the international community but also by Japanese businesses who understand how this discrimination hurts Japanese prospects as a country to invest in and do business with. Because of this discrimination, Germany suspended non-resident Japanese from being able to visit Germany until Japan grants the same travel rights to resident EU citizens as the EU grants to resident Japanese citizen.
The criticism and sanctions worked and Japan has finally announced a change in their policy. From September 1, foreign residents of Japan will be able to travel abroad and later return to Japan again, provided they follow some regulations. Before they depart they will have to agree to comply with enhanced quarantine regulations on return. Before they return they will have to take a PCR test and provide a negative test result. Besides the test result, they will need to provide a form filled in and signed or stamped by the hospital or doctor conducting the test (link, Microsft Word .docx format). They will be tested again on arrival. If the test is negative, they can go home to quarantine themselves for 14 days, provided they don’t use public transport (i.e. they must use a hire car or be picked up in a private vehicle).
