An angry war of words between Japan and Scotland has injected an element of needle into Sunday's typhoon-threatened Rugby World Cup clash in Yokohama.
Furious at threats of a formal Scottish protest if the crunch Pool A clash is cancelled, Japan coach Jamie Joseph felt the hosts had been disrespected, fuming that talk of legal action "undermined the achievements" of his side.
His opposite number, Gregor Townsend, hit back by saying he "had a good laugh" at the former All Black's comments, which were made with the help of prepared notes before he named his Japan side.
Scotland have to beat Japan to go through as two points for a cancelled match would see them knocked out.
Scottish Rugby chief executive Mark Dodson has insisted they won't become "collateral damage", saying he is prepared to take legal action if the game is called off.
World Rugby argues its rules were clear long before the tournament started, but the Scots believe a 'force majeure' clause compels officials to do all they can to get games on.
Significantly, however, when it looked like Ireland's game against Samoa on Saturday would fall victim to Hagibis, Scotland coach Gregor Townsend said: "The Ireland game cannot be postponed, it has to be played that day."
Given the bad blood, and how much is at stake, it would be little surprise to see tempers boil over if the match goes ahead.
Japan are looking to avenge a 45-10 defeat by Scotland at the 2015 World Cup that cost them a quarter-final spot, despite three wins including a 34-32 shock over South Africa.
After beating Russia 30-10, stunning Ireland 19-12 and thrashing Samoa 38-19, the Brave Blossoms are on the brink of history once again and Joseph expects a bruising encounter.
