Sanzar has officially completed the expansion of the Super Rugby competition to 18 teams in 2016.
Tokyo and Buenos Aires-based franchises can now start contracting players and staff ahead of their historic entry to Super Rugby in a little over 12 months from now.
They will join the South African side the Kings in the expanded competition that year.

The Japanese franchise will play three of their matches each year in Singapore, the city that missed out on hosting the asian team.
Both the Japanese and Argentinean teams will play in the South African Group and will be positioned in opposing conferences.
The final composition of these conferences are subject to approval by South African Rugby Union's General Council.
