Greig Laidlaw has been named Scotland's captain in their must-win encounter against Japan to be played in Yokohama this Sunday.
Scotland are positioned third in Pool A and will need a win against the Brave Blossoms in the final game of the opening round apart from denying them a bonus-point if they are to progress to the quarter-finals.
With Typhoon Hagibis expected to create havoc in the country, World Rugby has confirmed that they will wait until Sunday morning to take a call on the game after reviewing the conditions and a cancelled game will end Scotland's chances in the tournament unless Samoa get an unlikely win over Ireland.
Laidlaw is slotted at fly-half and will partner with Finn Russell with the duo set to surpass the record of Roy Laidlaw and John Rutherford, who made 35 starts together at half-back. Tommy Seymour and Darcy Graham have retained their position at wings and is joined by Stuart Hogg at fullback.
Sam Johnson and Chris Harris form a new centre partnership while Allan Dell, Fraser Brown and Willem Nel are at front-row with Grant Gilchrist and Jonny Gray at second row.
“The opportunity to face the hosts in such a decisive Pool match will be a unique occasion and should be a great spectacle," said head coach Gregor Townsend.
“Games of this magnitude don’t come around very often in a playing career so we will be giving it everything to make sure it is a memorable match.”
