Ireland will get an early chance to avenge their shock World Cup defeat to Japan in Dublin in a year's time.
World Rugby chairman Bill Beaumont has revealed that the Brave Blossoms will take on Andy Farrell's men during the new coach's first autumn window, with the Japanese Rugby Union confirming the fixture for November 21.
Ireland will also take on world champions South Africa and Australia in that international window, with Farrell set to take on the Wallabies twice in his first summer tour next July.
The match will be Japan's first visit to Lansdowne Road since they lost 78-9 in November 2000, having previously played at the venue during the pool stages of the 1991 World Cup when Ireland ran out 32-16 winners.

Japan will welcome beaten finalists England for a two-match series next summer, while they'll also face Scotland during their November tour as they look to build on their historic achievement in reaching a first World Cup quarter-final.
