Japan shock the world – again
Hosts Japan rocked the globe for the second time in four years by stunning Ireland 19-12 in their Pool A clash in Shizuoka.
The Brave Blossoms tore through Ireland time and time again, triumphing through superior tenacity and supreme intensity.
The world's 10th-ranked team beat the second-best outfit, who entered this tournament ranked number one in the standings.
Wing Kenki Fukuoka ran in the second-half try which sealed Japan's famous victory – invoking memories of their breathless 34-32 win over South Africa in Brighton at the 2015 World Cup.
Springboks bounce back
Japan's win over Ireland will see them move to an all-time high of eighth in the world rankings – which their opponents had topped coming into the tournament.
Coming up
Can Wales bounce the Wallabies?
Wales have been left in no doubt of just what their showdown with Australia at Tokyo Stadium means.
Victory for either side on Sunday would see them become favourites to finish top of Pool D – and potentially open up a more straightforward route in the knockout phase.
England and New Zealand, though, are set to loom large for the losers.
"Let's be honest, we have been preparing for this since the draw was made," said Wales assistant coach Shaun Edwards.
"I said to the players, this is a game they will remember for the rest of their lives and we want to be successful in it."
