Japan plans to lift a state of emergency in Tokyo on June 20, a month before the Olympics begin.
The capital city and various other regions have been under a virus emergency since April 25.
Japan is considering allowing spectators at the Olympics, though there is no official confirmation yet.
Relaxation of restrictions could allow 10,000 people, or 50% of the venue capacity at sporting events.
An announcement is expected later Thursday after top officials discuss the matter with medical advisers.
