Scotland says it expects contingency plans to be put in place to play its crucial match against Japan, even though World Rugby says there are no backup plans if it has to cancel the match on Sunday because of Typhoon Hagibis.
World Rugby says the game is going ahead in Yokohama as scheduled but it will be under review until hours before kickoff.
Scotland must beat Japan to reach the quarterfinals. If the game is cancelled, Japan, which leads Scotland by four points in the Pool A standings, will advance to its first quarterfinal and Scotland will miss out.
"We are in regular dialogue with World Rugby at all levels to work to ensure our fixture against Japan on Sunday can be played as planned. Public safety is the clear priority," Scottish Rugby said in a statement.
"With potential impact on our last Pool A fixture, Scottish Rugby fully expects contingency plans to be put in place to enable Scotland to contest for a place in the quarterfinals on the pitch, and will be flexible to accommodate this."
But the rules state that if a pool game can't be played on its scheduled date, it will be cancelled and logged as a draw with two points each to the teams.
World Rugby said: "Every effort is being made to ensure Sunday's matches will be played as scheduled. A thorough assessment of venues will take place after the typhoon has passed before a final decision is made on Sunday morning."
Tournament director Alan Gilpin said the rules of the tournament had been made clear to all teams prior to them signing their participation agreement, and that treating one game differently would be impossible, no matter the stakes, Kyodo News reported.
Scotland is scheduled to move to its Yokohama hotel on Friday.
Meanwhile, England is leaving Tokyo for Miyazaki on the southern island of Kyushu to avoid Typhoon Hagibis.
The England-France pool match scheduled for Saturday in Yokohama was cancelled by Rugby World Cup organizers because that is when and where the approaching storm, the most powerful this year, is expected to make landfall.
Miyazaki hosted England's pre-tournament training camp.
It's also not far from Oita, where England's quarterfinal against Wales or Australia is scheduled next week.
"We'll have a short camp in Miyazaki and then we're off to Oita," Jones said. "We have an exceptional record in two-week preparations."© Copyright 2019 The Associated Press. All rights reserved. This material may not be published, broadcast, rewritten or redistributed.
