Japan v Russia
Home fans won't have to wait long to see their team in action, with host nation Japan meeting Russia in the first game of the Rugby World Cup.
Japan, coached by Kiwi Jamie Joseph, go into the match as overwhelming favourites to kick off their campaign with a win to their name. But if the last time the two sides met is anything to go by, the match might not be as one-sided as anticipated.
Japan and Russia met in November of 2018 where the Brave Blossoms had to produce a second-half comeback to take the win. However, this time around they're expected to benefit from a home advantage.
The temperatures throughout the World Cup are expected to be high and humidity will be high. Look for Japan to move the ball and force the Russians to burn their energy early.
