Ireland vs Japan Prediction, Odds & Best Bets | Nations Championship 2026
Japan Won’t Make it Easy
Ireland return to action looking to build momentum in the inaugural Nations Championship when they face Japan at McDonald Jones Stadium in Newcastle, Australia.
The Irish are one of the world’s elite sides, but Japan have built a reputation for causing problems for bigger nations with their high-tempo, expansive style of rugby. Eddie Jones’ men arrive full of confidence after defeating Italy, while Andy Farrell’s squad will want another polished performance before their huge showdown with New Zealand.
Match Details:
- Fixture: Ireland vs Japan
- Competition: Nations Championship – Round 2
- Venue: McDonald Jones Stadium, Newcastle, Australia.
- Date: Saturday, 11 July 2026
- Kick-off (South Africa): 12:10 SAST
Ireland Looking to Sharpen Their Physical Edge
After their victory over Australia, Farrell admitted there were still areas his side could improve, particularly around physicality and winning collisions. The Ireland coaching staff have made it clear that the Japan match is another opportunity to develop that edge before tougher tests later in the competition.
Several fresh faces are expected to receive opportunities, with Farrell continuing to build squad depth ahead of the 2027 Rugby World Cup. Three potential debutants have been included in the wider squad, while injuries have forced a few late adjustments. Prop Jeremy Loughman has already been ruled out following concussion protocols after the Australia victory.
Japan Cannot be Underestimated
South African rugby fans know better than most that Japan are capable of producing fearless rugby. Although Ireland have dominated recent meetings, Eddie Jones has assembled an exciting squad that thrives on quick ball movement and relentless work rate.
Japan have an impressive win over Italy under their belt and will be motivated after travel frustrations surrounding the fixture, which is technically one of Japan’s home matches despite being played in Australia.
If Ireland allow Japan to dictate the tempo, the Brave Blossoms could keep the game competitive far longer than many expect.
Head-to-head
Ireland have had the upper hand in these fixtures over the past decade.
The most memorable result remains Japan’s famous victory at the 2019 Rugby World Cup, but Ireland have won every meeting since then, including a convincing 60-5 victory in Dublin during the 2025 Autumn Nations Series.

Ireland vs Japan Prediction
Japan will throw plenty at Ireland during the opening exchanges, but the Irish pack should eventually wear them down. Farrell’s squad possesses significantly greater depth, superior set-piece quality and enough strike runners to stretch Japan once fatigue sets in.
We expect Ireland to pull away during the second half.
Prediction: Ireland 38-17 Japan
