It’s safe to say the two nations head into this clash on the back of a mixed 12 months.
Although Ireland currently top the world rankings, there’s no doubt the side has blown hot and cold this year. A record defeat by England this summer set alarm bells ringing before a sense of normality was restored with back-to-back wins over Wales.
As for Scotland, the disappointment of their 2019 Six Nations was offset by that thrilling 38-38 draw against England in which Gregor Townsend’s men showed that they possess the means to challenge the game’s biggest and best sides.
Either way, Sunday’s encounter will be a fascinating encounter and one which could determine the winners of Pool A.
When is it?
Ireland vs Scotland kicks off at 8.45am (BST) on Sunday 22 September. The match is being played at Yokohama’s Nissan Stadium.
Where can I watch it?

Both teams were subject to disappointing defeats over the summer – Scotland against France, Ireland against England – before enjoying a series of encouraging wins that once again raised hopes heading to Japan.
Although the head-to-head between these sides is remarkably close (Scotland – 66, Ireland – 62), the Irish have looked the superior the team in recent years. Whereas Scotland can be somewhat dependent on the brilliance of a handful of key individuals, you feel Ireland are more polished as a collective unit when they get it right. I’m expecting a narrow win for Joe Schmidt and his men.
