According to Stuart Hogg, Scotland must be ready to play its biggest game of his life to reach the final eight games of the World Cup.

Gregor Townsend's team will face Japan in Yokohama on Sunday and reach the quarter-finals with a win of at least eight points.

The typhoon Hagibis could still throw a tug and banish the Dark Blues from the tournament, if World Rugby believes that the match is not safe and triggers a draw.

But Hogg prepares as if the game will start as planned at the 70,000-capacity International Stadium, and wants his team to gauge the magnitude of the event.

"I think it would definitely be the best thing I've done so far," said Scotland's star-back.

"We've been working incredibly hard to get where we want to go since the beginning of June, and on Sunday we have a chance to relax and reach a quarter-final."

"For me and many of the guys, this could be the biggest game of our career and we're looking forward to it.

"It's a huge test match for us, but the majority of the team has played in big games, and there are many experienced guys.

"It's going to be a hell of a fight."

Scotland had a bleak start as they collapsed in their opening game against Ireland.

But this weekend, they return to the same spot where Joe Smith's men had earned each other bonus points without conceding a single goal against Samoa and Russia.

Now Hogg has called on his side to maintain their recent standards and not go back to the sloppy ways they have injured the last time in Yokohama.

"For us as a professional player, we have to be on the money at every opportunity," said the British and Irish Lion. "We made it difficult to start this tournament.

"But we still have a chance to reach the quarter-finals in the last game."

"The Japanese players are all great personalities who also play very well together.

"We need to make sure that our defense has the money it needs to eliminate it at the earliest opportunity and then take advantage of our chances to attack.

"But we are aware of the strengths that they have – but we also see opportunities – there are some tasty games, but we are confident that we can win this friendly."

The Japanese public has been grateful to the Scots over the past few weeks, with Greig Laidlaw taking over the captain against the Brave Blossoms after Stuart McInally has fallen on the bench – the unlikely pin-up boy.

But they are now being cast as the villains who want to kill the hosts' hopes for a fairy tale until the end of the Eight.

However, anger with the locals is Hogg's least concern.

He said, "We've had a great time in Japan so far, we've had a lot of different experiences, and Gordy Reid's Instagram and Twitter posts show he's having fun.

"But we came here with a job and that was to win friendly matches. We have a chance to play against the host country and it will not get bigger.

"The focus is on it and we have to do everything we can to take another step forward.

"Are we the outsiders? We do not bother us as what we are branded.

"They will come out of the blocks and shoot. We have to bring them together and improve them. These are the games you want to play as an international rugby player. I wish it was Sunday night. "
