Wales fly-half Dan Biggar looks set to be available to face Fiji as he returns to training with five days to go.
Warren Gatland’s side travel to Oita on Sunday as they look to consolidate their place at the top of Pool D against a dangerous Fiji side.
There had been concerns over Biggar after he failed a head injury assessment during the rip-roaring 29-25 victory over Australia last Sunday.
He was taken from the field after a thunderous collision with the bulldozing Samu Kerevi around the half hour mark and never returned.
The Northampton Saint has been going through the return-to-play protocols ever since, while the squad have had a few days off to recover in Otsu.
However, they were back in training on Friday morning, with Biggar taking part.
"He’s back in training", defence coach Shaun Edwards said.
"Dan’s tough as old boots, isn’t he?
"He’s an incredibly tough player and it would have to be a pretty serious injury to keep him off the training pitch."
When asked if he would be available to face Fiji, Edwards said: "We’re hoping so, yeah."
During that victory over Fiji, Rhys Patchell’s tackle technique was criticised by Wallabies skipper Michael Hooper.
Centre Kerevi was penalised for raising his forearm while carrying the ball down Patchell’s channel, leaving Hooper incredulous.
"Should we not run into the tackle there?" Hooper said to referee Romain Poite during the game.
"That’s just terrible tackle technique and you can’t carry the ball if that’s going to be the ruling."
But Edwards has little time for Hooper’s comments.
"Rhys did what we asked of him", the coach explained. "We asked him to tackle a little bit higher than he has been and to go in and create the collision.
"Michael Hooper is entitled to his opinion, as is everyone else."
The victory over Australia earned them control of their group and put Wales in a very promising position.
It’s a positive start that has led to a surge in optimism back home in Wales, and Edwards has now insisted that anything less than a semi-final would be unsatisfactory.
"As a coaching group, we have been in the semi-final once. I think the two games we’ve just won... if we don’t win our next three I will be unbelievably disappointed."
Edwards also hinted that we should expect a strong side to be named against Fiji to hopefully go out and get a third consecutive win.
Then there would be changes for the final game of the group stage against Uruguay in Kumamoto.
When asked how they manage the morale of players who are facing a third game in the stands, he said: "Tell them they are playing in the fourth game! Which is what Gats did this morning."
