Japan's prime minister, Shinzo Abe, will consult with experts at a meeting on Monday to extend the national state of emergency until May 31, news agency Reuters reported quoting broadcaster NHK on Sunday.
The government will also discuss further action on how to prevent the spread of the novel coronavirus epidemic, the report added.
The virus has so far infected 15,589 people and killed 530 in the country.
The current state of emergency is set to expire on Wednesday, the last day of a week-long national holiday.
Japan's economy minister said earlier the country could also ease some of the current coronavirus-related curbs on economic activity by allowing places such as parks and museums to reopen, provided proper preventive measures were in place.
