Ireland return to the Aviva Stadium for their second match of the 2025 Autumn Nations Series, determined to respond after a tough loss to New Zealand. Andy Farrell’s men suffered a 26–13 defeat to the All Blacks in Chicago, playing most of the match a man down after Tadhg Beirne’s early red card. Despite that setback, Ireland’s form remains strong — nine wins in their last eleven Tests — and they’ll be heavy favourites to get back on track against Japan.
The Brave Blossoms, meanwhile, arrive in Dublin on a three-match losing streak, including a 61–7 hammering by South Africa. Ranked ten places below Ireland, they’ve struggled to match top-tier sides recently and face a daunting task at one of rugby’s toughest venues.
Team Form & Recent Results
Ireland:
Ireland’s performance under Andy Farrell has been defined by consistency and control. Even with rotation in the squad, their attacking systems and breakdown efficiency have been elite. Before the defeat to New Zealand, Ireland had strung together convincing wins over Portugal (106–7), Georgia (34–5), and Italy (22–17) earlier this year. Their home form has been particularly strong, averaging more than 35 points per game at the Aviva Stadium in 2025.
Japan:
Japan’s recent form tells a very different story. After winning the Pacific Nations Cup semi-final against Tonga, they’ve stumbled against stronger opposition. Defeats to Fiji, Australia, and South Africa have exposed defensive weaknesses and a lack of composure in key moments. Eddie Jones’ side still play attractive rugby — quick tempo, wide ball movement — but they’ve struggled to sustain intensity against top-eight nations.
Head-to-Head Record
Ireland and Japan have met six times in the past decade, with Ireland winning five. The only Japanese victory came at the 2019 Rugby World Cup in Shizuoka (19–12), a famous upset that remains fresh in memory. Since then, however, Ireland have reasserted dominance — including a crushing 60–5 win in their last meeting. The average margin of victory for Ireland in recent head-to-heads is nearly 40 points, underlining their superiority.
Lineups, Injuries & Team News
Ireland (Expected):
Andy Farrell is likely to make a few changes from the side that faced New Zealand. Peter O’Mahony and Caelan Doris should return to the starting XV, while Finlay Bealham is tipped to start in the front row. Hugo Keenan and James Lowe remain key attacking threats in the back three, while Jack Crowley continues to grow in the fly-half role.
Unavailable: Tadhg Beirne (suspended), Garry Ringrose (injury), Jamison Gibson-Park (rested).
Japan (Expected):
Eddie Jones will field an experienced side led by captain Michael Leitch. Kotaro Matsushima is expected to start at full-back, while Dylan Riley and Tomoki Osada will line up in midfield. Fly-half Lee Seung-Sin will direct play, though much depends on how Japan’s pack handles Ireland’s physicality at the breakdown.
Tactical Analysis & Key Players
Ireland will look to control possession and territory through structured phases and a powerful kicking game. Expect them to use lineout mauls and fast ruck ball to stretch Japan’s defence. The pairing of Jack Crowley and Bundee Aki offers a blend of creativity and power in midfield, while Caelan Doris remains central to Ireland’s link play between forwards and backs.
Japan’s best chance lies in quick transitions. Their backline thrives on turnover ball, but their scrum and lineout have been exposed by stronger sides. Discipline will be key — Ireland’s accurate kicking from hand and relentless phase pressure can quickly punish penalties in the wrong areas.
