(CNN) Scottish rugby officials have sought legal advice on whether its crucial Rugby World Cup clash with host Japan can be canceled because of the threat of Typhoon Hagibis.

The Scots are due to face Japan in Yokohama Sunday in a game they must win to have a realistic chance of progressing to the knockout stages, but the match could be called off for safety reasons.

Japan is top of Pool A on 14 points with world No.1 Ireland, which takes on Samoa Saturday, in second on 11 points and Scotland third on 10.
