That's it from us for now.

We'll be back on Thursday for more action from the Women's Rugby World Cup.

The Irish fans rise as one to salute an incredible second-half comeback.

A 10-point victory seemed unthinkable half an hour ago but the forwards turned this one around to keep their World Cup dreams alive.

The Japanese take a bow - and rightly so. They more than played their part in an enjoyable game.

So results today mean Wales are out of contention for the semi-finals in Belfast.

But Ireland and England both have two wins from two matches, so it all goes down to the final group games on Thursday.

England will face three-time finalists the USA while hosts Ireland meet France.

It's all over.

It wasn't pretty and Irish nerves are completely wracked but somehow Ireland eke out a victory against a brave Japanese side who deserve all the credit in the world.

Relief is etched on the faces of the Irish players, staff and supporters who now go into Thursday's pivotal game against France with two wins from two.

There's three minutes left to play at the UCD and Ireland are three points ahead.

You can only imagine how nervous the home fans are right now.

Ireland move ahead for the first time in the game with a penalty from Nora Stapleton in front of the posts.

Emily Belchos' conversion doesn't clear the posts but it doesn't matter.

Canada still come away with the win and still haven't conceded in the World Cup.

Ireland put together 19 phases of play as they lay siege on the Japan line in a bid to secure the victory they desperately need.

Wales have a decent spell of possession but they can't get out of their own half.

A big carry by Robyn Wilkins, who's come off the bench, is fed to Jess Kavanagh-Williams but the balls goes into touch.

We're into the red on the clock.

Ireland have never got going out wide so scoring off a set piece was their best route back into this game and Paula Fitzpatrick's try off a rolling maul somehow has dragged Ireland level.

The crowd are trying to lift them to summon up a big finish.

Canada go on the attack and Magali Harvey makes headway up the right flank, as she has done so much in this match, but she's bundled into touch for a Wales line-out.

Both teams are back to full strength now after the two sin-bins.

Wales concede another penalty for an infringement at the ruck and once again Canada opt to kick between the posts.

Magali Harvey is over 30 metres out but it's straight for the wing.

But she can't get the distance on it. The ball dips under the posts.

A quarter of this match to go and the outcome is still in the balance.

Ireland's hopes of making the World Cup semi-finals on home soil most likely rest on winning this game but as it stands those ambitions hang by a thread.

With both sides a player down, Hannah Jones is penalised for not rolling away and Canada opt to go for the posts.

Magali Harvey steps up. She's on the 22 metre line, but it's pretty central.

It's clear! Canada extend their lead.

That could be a turning point.

Wales captain Carys Phillips joins Canada's Julianne Zussman in the sin-bin.

There are 13 minutes left and, boldly, Canada have turned down an easy kick at goal and opted for a scrum.

Magali Harvey, the Canada wing, is almost waif-like for a rugby player but she has just landed a huge hit on Wales full-back Dyddgu Hywel.

Canada turn the screws in attack as they make their way into Welsh territory.

The referee blows up after an infringement at the breakdown and it looks like Carys Phillips is going to get a yellow card.

She had been warned...

Canada are down to 14 players for 10 minutes, as full-back Julianne Zussman is rightly carded for stamping.

What can Wales do here?
