The Japanese government will request that all arrivals submit negative coronavirus test results that were certified in the 72 hours leading up to their departure.
The measure will take effect on Wednesday next week, Japan time. It will likely remain in place until the government lifts the state of emergency that is currently in effect for Tokyo and its three neighboring prefectures.
Additionally, entrants will be asked to undergo tests upon arrival at airports in Japan.
Authorities will ask people who can't submit certifications to self-quarantine at designated accommodation facilities and take tests on their third day in Japan.
Even if the tests confirm arrivals are not infected, authorities will ask them to pledge to download a contact-tracing app and keep records of their location information. The entrants will also be asked to self-quarantine at home or elsewhere for 14 days after arriving in Japan.
In a related development, NHK has learned that the Japanese government is considering revising the quarantine law.
A possible revision would grant legal authority to officials to ask arrivals in Japan to self-quarantine at home or elsewhere for 14 days after entry, and to isolate those who refuse at designated facilities. People who decline to be isolated would face criminal punishments, such as imprisonment and fines.
Currently, some arrivals are not complying with self-quarantine requests, which lack the force of law.
