Jack Conan and the two Prendergasts have been really impressive since coming on and have brought plenty of energy. Ireland's strength in depth on show
Ireland 22-10 Japan
Gus McCarthy and Finlay Bealham are on for Thomas Clarkson and Ronan Kelleher.
Ireland 22-10 Japan
Play is brought back for the penalty from the scrum and Sam Prendergast sends it deep into the 22.
Ireland 22-10 Japan
Jacob Stockdale shows some nice feet and Cian Prendergast makes more metres with a big carry.
It's kicked across to Tommy O'Brien but he can't gather and it spills forward.
Ireland 22-10 Japan
Japan are throwing the ball about again but a sloppy pass means any chance of an attack slips away.
Ireland 22-10 Japan
Cian Prendergast was offside and he was the one who charged down the clearing kick.
So the try is ruled out.
Ireland 27-10 Japan
It was a kick through by Tommy O'Brien and there's a bit of a mess which allows Jacob Stockdale to pounce on the loose ball to score.
But we're looking to see if the Ulster wing, or Cian Prendergast, were offside.
Jacob Stockdale
Out of nothing!
But we're going to the TMO.
Ireland 22-10 Japan
Ireland can clear and there's some more kick tennis between the sides.
Sam Prendergast is crunched by two Japan forwards in his first action since coming on.
Ireland 22-10 Japan
Japan have the penalty and pop it into the corner.
The maul can't get rolling and any momentum is stalled.

Nice moment for the Prendergast family as brothers Cian and Sam run on to the field together.
Ireland 22-10 Japan
Jacob Stockdale is back on for Ireland.
Sam Prendergast, Cian Prendergast and Jack Conan come on as Andy Farrell makes some changes.

Rory Best

One area that Japan have struggled in today is knowing when to commit to runners when Ireland have options. They bit in on the wrong man there and gave Ireland space.
Ireland 22-10 Japan
Michael Leitch is on for Japan. A true legend of the game.
Ireland 22-10 Japan
It's a poor clearance from Crowley and Japan have the throw on the edge of the 22.

Brian O'Driscoll
Former Ireland captain on TNT Sport
It has taken Ireland a few minutes to get into the swing of things in this second half but that's good hands and a big game player with the try.

Ian Humphreys
Former Ulster fly-half Ian Humphreys on BBC Radio Ulster
That is a brilliant set-up play from Ireland off the lineout and the multi-phase is great.
Andrew Porter
That's much more like it.
Japan were stretched after that Doris carry.
Tommy O'Brien made more ground on the other wing, and Andrew Porter was never going to be stopped from close range.
Crowley sends his conversion attempt wide.

Ireland 17-10 Japan
Caelan Doris charges forwards the line and it was one offload away from a walk-in try for Tommy O'Brien.
Brilliant, yet slightly desperate defence from Japan.
Ireland 17-10 Japan
It's another messy line-out from Ireland but Japan are penalised. Jack Crowley sends it deep in the 22.
