Reported infections in Japan have trended down in recent days but the government has signalled it would remain cautious.
Japan last month imposed a one-month state of emergency for 11 areas, including Tokyo, neighbouring prefectures and the western city of Osaka.
It had decided to extend the emergency in 10 of the 11 prefectures until March 7, as the medical system remained under pressure despite a decline in the number of cases.
The country has had more than 390,000 cases of the coronavirus and 5,832 deaths, and is desperate to stamp out flare-ups of infection as it prepares for the summer Games, due to begin on July 23.
