Scotland named their side Friday for their crunch game with Japan at the weekend amid an increasing war of words between the Scottish Rugby Union and Rugby World Cup organizers, a clash Japan coach Jamie Joseph also weighed in on.

Sunday's game at Yokohama, which the Scots must win if they are to reach the quarterfinals, could be called off depending on the impact of Typhoon Hagibis. And with so much at stake the SRU has hinted at legal action if there is no change to organizer's plans not to delay the game to another day.

"For World Rugby to just simply state that the game has to be cancelled goes against the whole sporting integrity of the tournament," SRU Chief Executive Mark Dodson told BBC Radio 4's Today Programme.

"World Rugby seem to be determined to stick to its plan that the match is either played on Sunday or indeed it is cancelled, and to have it cancelled and have our ability to progress from this group put at peril, we believe is absolutely unacceptable."

"We have been preparing for this tournament now for four years."

Dodson says the SRU have taken legal advice to challenge the decision not to play the Japan game on Monday if needed, adding "My view is that we're not going to let Scotland be the collateral damage for a decision that was taken in haste."

Japan coach Joseph, however, fired back at the possibility of any legal intervention.

"All the talk of legal proceedings around something uncontrollable like a typhoon ignores how significant this match is for us," he said.

"I would say it is the most significant in our history. We have never made the quarterfinals before and we have never beaten Scotland. We want to have the chance to achieve those firsts, but we know it will be difficult against a good, experienced team."

On Thursday, England's match against France in Yokohama and New Zealand's clash with Italy in Toyota were both called off -- causing Italy captain Sergio Parisse to accuse World Rugby of double standards, given his side still had a mathematical chance of reaching the last eight.

"If New Zealand needed four or five points against us, it would not have been cancelled. It is ridiculous that there was no Plan B because it isn't news that typhoons hit Japan."

Cancellations see the games recorded as 0-0 draws with both sides awarded two points.

If Ireland beat Samoa on Saturday night in Fukuoka, such a result would see the Scots on the next flight home.

The Scots are furious World Rugby is refusing to delay matches or move them, especially as there is a gap of at least six days before the quarterfinals are played.

"We're willing to do whatever it takes to get this game on," said a SRU spokesman. "There are 10,000 Scotland supporters here to see their team play, and for the integrity of the sport and this tournament, we've got to find a way to deliver on our undertaking to stage this game."

If the game does go ahead Sunday, those fans will see a Scotland side showing 12 changes from the team that beat Russia on Wednesday, when Townsend rested the majority of his frontline players.

Stuart McInally, who captained Scotland against Ireland and Samoa, starts on the bench with Fraser Brown, who played the first 30 minutes of Wednesday's 61-0 win at open-side flanker, wearing the No. 2 jersey.

Darcy Graham continues on the left wing, and Tommy Seymour keeps his place on the right wing after playing 80 minutes against Russia.
