Rhys Carre, Kieron Assiratti and Taine Plumtree are on for Wales.

Props Nicky Smith and Archie Griffin plus Aaron Wainwright off.

Wales have a penalty and kick for the corner...

Seungsin Lee makes no mistake and Japan deservedly have the lead.

What are you made of, Tandy's Wales?

Dan Edwards is pinged for offside and Japan will kick for the lead.

Central, 30 metres out and they should get their noses in front.

Japan are doing all the pressing again.

Wales are unable to disrupt them at the breakdown - could Wales have done with Tommy Reffell - and they are going through the phases.

Japan kick to the corner and will test out Wales' line-out.

Dewi Lake finds Aaron Wainwright and it's a good exit.

20 minutes down to 14, how costly is that going to be for Wales now?

Japan threaten again but Wales are saved by a forward pass as they burst into the 22.

The excellent Warner Dearns the man who couldn't produce the pass.

Japan get us back under way and Wales have almost 20 minutes to get through down to 14 men. Adams won't be the man that returns after that.

Before things get back under way, referee Matthew Carley informs us that Josh Adams' yellow card has been upgraded to a 20-minute red.

Like we mentioned in the build-up, it's a pretty important day for both shaped balls in Welsh sport.

Well good news, Wales men's football side is currently leading Liechtenstein 1-0 in their crucial World Cup qualifier some 850 miles away.

Can the rugby team follow suit? The second half is on the way.

Louis Rees-Zammit doesn't seem quite there in terms of sharpness. He has little bursts, and it seems to take him a minute or two to get back into the game.

The moments we've seen have been exciting and have got the crowd on their feet.

A reminder of how important this game is for the World Cup in 2027.

The draw is made on 3 December and if Japan draw or win then they will go above Wales in the world rankings.

That would mean Steve Tandy's men are at risk of being in the third batch of teams for the new 24-team tournament.

There would be the possibility of Wales being in a group of death with, for example, South Africa, Argentina and Tonga.

This is a huge 40 minutes for the long term.

What does Steve Tandy have on his bench if he wants to shake things up?

Props Rhys Carre and Keiron Assiratti performed strongly when starting last week while Taine Plumtree will be keen to make an impact after missing out on the 23 against the Pumas.

In terms of backs, fly-half Jarrod Evans is of the Dan Edwards mould while centre Nick Tompkins has been in good form for Saracens.

Max Llewellyn hasn't been able to make much of an impact so far.

Towards the end of the second-half we missed far too many tackles which allowed Japan to be on the front foot.

It's been all Japan since Wales' try.

We're all square in Cardiff, but let's bring you up to date with what's happening elsewhere today.

Wales were insipid in attack in that first half and could not take advantage of two extra men.

Japan were by the far more dangerous side in attack and Wales will have to improve markedly in this second half.

Dylan Riley is laying the ball back and Josh Adams hits him. That's just really clumsy.

It's a really poor attempt at a counter-ruck.

Lee strikes the left post with his penalty attempt and Wales scramble to deal with the loose ball.

It's level at the break.

Pretty poor from Wales and Steve Tandy has a lot to address at half-time.

They will also wait to see if Josh Adams' yellow card remains yellow rather than being upgraded.

A TMO check for an illegal clear-out by Wales wing Josh Adams.

Silly by the experienced Cardiff back and they will finish the half down to 14 and start the second a man down.

Japan will kick for goal...

There was plenty of positivity thanks to the attack against Argentina but this has been a poor first half against Japan.

The tourists have been the better side despite the yellow cards.

They will finish on the attack...

Japan are back to 14 men without any damage on the scoreboard.

Just under three minutes left of the other yellow.

Can Wales sneak in front before the break?
