After beginning their World Cup campaign with an impressive 27-3 win over Scotland, Ireland take on the hosts Japan.
Joe Schmidt's side reminded of their imperious 2018 best when seeing off their Six Nations rivals in Yokohama.
It was a result that has many looking ahead to a World Cup quarter-final with South Africa.
But there is matches to be played until that possibility and they will take on a country who memorably caused an almighty upset against the Springboks four years ago.
Japan did not impress in their curtain-raising victory over Russia and they will be heavy underdogs against Ireland.
