Jamie Joseph’s men beat Scotland 28-21 in a thrilling encounter last weekend to secure their first-ever place in the last eight.
The fixture faced the threat of cancellation due to Typhoon Hagibis, which would have seen Japan qualify to the knockout stages regardless, but the green light was given on the morning of the match.
Whereas the hosts qualified top of Pool A, having won all four of their games, South Africa finished second in Pool B, one point behind rivals New Zealand.
Sunday’s quarter-final will be the first time the two sides have met at the World Cup since Japan’s famous win over the Springboks in 2015. They did, however, face off earlier this summer in a World Cup warm-up, with Rassie Erasmus’ men romping to a 41-7 victory.
