England and Japan will play their first official Test on Japanese soil when they clash at a humid National Stadium in Tokyo on Saturday.

Here the PA news agency looks at five talking points for a game Steve Borthwick’s men enter as strong favourites.

Master v apprentice

Possibly more interesting than an encounter England should win comfortably is the sub plot of Eddie Jones’s first confrontation with his former employers and first head to head with Borthwick, his number two at Twickenham and during his first spell with the Brave Blossoms. It is a fascinating duel that pits veteran Jones against the man who he guided for the first seven years of his coaching career. Both will be desperate to win.

All Blacks curtain raiser

Bigger tests than Japan await England on their summer tour and with New Zealand looming in a fortnight, Borthwick has selected a side that is close to first choice in the hope of building cohesion and momentum. The conditions in Tokyo and Dunedin – the setting for their first clash with the All Blacks – will be as different as the quality of the opposition, but a conclusive victory is still vital.

Smith’s time to shine

George Ford was masterful as England finished the Six Nations by finding their mojo against Ireland and France but with the veteran fly-half absent through injury, Marcus Smith will pull the strings against Japan. Smith has always been operating in the shadow of Ford or Owen Farrell but with both of them out of the picture, it is time for the Harlequins’ playmaker to prove he can provide the game management to match his creativity on the Test stage.

The indestructible man

When Tom Curry steps off the bench at National Stadium, it will complete a remarkable comeback for a player who has had just 34 minutes of action since last autumn’s World Cup. Curry underwent surgery to repair a career-threatening hip injury and despite the prognosis that he would not return until next season – if at all – he has shown remarkable powers of recovery to be involved on the summer tour. England will need his influence, especially in defence, if they are to topple the All Blacks.

Under reconstruction

Japan field four debutants including a player who still turns out for his university side as they begin rebuilding for the 2027 World Cup. It was classic Jones picking Yoshitaka Yazaki at full-back even though he has yet to appear in a professional game, but the Australian is convinced the 20-year-old is ready for the step up. Japan intend playing fast and loose to suit their strengths and need to avoid an arm wrestle up front, especially with two of those debutants appearing in the front row.
