Fly-half Sacha Feinberg-Mngomezulu and winger Kurt-Lee Arendse scored two tries each as South Africa cruised to a 61-7 victory over Japan at a sodden Wembley Stadium in London on Saturday.
The Springboks scored nine tries as there was no repeat of the "Miracle of Brighton" when Japan stunned South Africa with a 34-32 victory at the 2015 Rugby World Cup, considered one of the great upsets in rugby history.
Flankers Siya Kolisi and Andre Esterhuizen, the latter moved from his usual centre position, prop Wilco Louw and centre Jesse Kriel also crossed the line as Springbok forward dominance laid the platform for a comfortable win.
Japan's lone try came via full-back Yoshitaka Yazaki in a rare entry into the Springbok 22, but they could not cope with the physicality of their opponents in difficult conditions.
"I thought we did what we wanted to do, we made a couple of mistakes but credit to Japan, they played with pace and moved the ball quickly," Springboks captain Kolisi said.
"We tried to slow it down at the breakdown and make our hits. We had to work for everything we got today."
South Africa will face a step up in opposition against France in Paris next week, with further games in the Autumn International series against Italy, Ireland on 22 November and Wales.
South Africa will, however, be sweating on the fitness of prop Ox Nche, who limped off after 19 minutes with an ankle injury.
The Springboks led 26-0 at halftime and were never under any concerted pressure, with both sides struggling in the wet conditions that made the ball difficult to handle.
Japan were not helped by yellow cards for prop Shuhei Takeuchi and flanker Ben Gunter that meant 20 minutes with 14 players.
Elsewhere, Darcy Graham and Jamie Dobie claimed hat-tricks as Scotland ran in 13 unanswered tries to romp to an 85-0 victory over the US in Saturday's Test at Murrayfield.
Duhan van der Merwe added two more and Dylan Richardson, Kyle Rowe, captain Stafford McDowall, George Horne and Ollie Smith also crossed in a one-sided win for the hosts.
Flanker Richardson began the rout after five minutes and the home side quickly scored two more as Van der Merwe and Graham continued their duel for the mantle of Scotland’s record try scorer.
Graham started the game one behind Van der Merwe (below), who was earning his 50th cap, but they now have 34 tries each for Scotland.
The Scots had scored seven tries by half-time, prompting coach Gregor Townsend to make a raft of changes, but they kept up the tempo after the break with six more, highlighted by Dobie completing his hat-trick after he moving from scrum-half to the wing.
They fell seven points shy, however, of matching their record 100-8 win over Japan in Perth in 2004.
Scotland face a much more daunting challenge next weekend when they take on New Zealand at Murrayfield, when they will be able to pick from their players with English and French clubs.
