The Japanese government says coronavirus vaccine certificates that the country issues will be valid in five nations, including Italy and Austria.

It said people with the proof of vaccination will be exempt from self-quarantine rules, or face relaxed requirements, when entering Italy, Austria, Turkey, Bulgaria or Poland.

The government says South Korea recognizes Japanese certificates as one of the documents required to get exemptions from the country's isolation measures.

Those who have valid Japanese passports will be able to apply for the certificates through municipality offices, starting from Monday.

Chief Cabinet Secretary Kato Katsunobu told reporters that Japan will negotiate with other governments in order to make the certificates valid in more countries.
