Fiji and Japan will join the Six Nations sides in an eight team tournament that is set to replace this year's Autumn Tests.
The BBC reports that it will begin on 14th November - two weeks after the final round of the 2020 Six Nations is completed.
Fiji will face England, Wales and Ireland in one group while in the other pool, Scotland will host Japan and France at Murrayfield and face Italy in Rome.
The tournament will be staged on four consecutive weekends until 5th December, with each team facing their equivalent in the other pool on the final weekend, with the venue to be decided.
Official confirmation of the schedule and the venues is expected in August.
