The matchday 23 is the same as the side that defeated host Japan 7-41 at Kumagaya Rugby Stadium in the warm-up game earlier this month while Siya Kolisi's return is the only change from the starting line-up that went on to draw 16-16 against All Blacks.
Prop Trevor Nyakane has found a place on the bench despite having concern over his fitness while Kwagga Smith Sbu Nkosi miss out.
"We've found some consistency and some momentum in a number of ways this season and one of them is in selection," Erasmus said.
"We have 31 players in the squad, any of whom I would be happy to select. but this is a line-up that has worked well as a starting combination and one with real momentum to come from the bench.
"We're continuing to develop and new players are always pushing a claim but we've prepared well and we're looking forward to what will be another extremely close match."
