The city has not allowed players to practice in public until now due to coronavirus fears. But officials gave the go-ahead on Tuesday, after confirming that sufficient anti-infection measures were in place.

Spectators, including journalists, were required to submit a written oath confirming their health condition and disinfect hands before entering the ballpark.

Australian players in yellow uniforms and masks then carried out some light exercise before continuing with batting practice.

Five practice games between the Australian squad and Japanese teams are scheduled over the coming week, with up to 500 spectators allowed in the stands.

Municipal official Osawa Hidetoshi pledged to continue taking steps to ensure that spectators can safely watch the Australian team in action.
