Wales' defence needs to be strong now.
I'm sure Japan want to start playing rugby now, they won't want a loose game when they're chasing.
Japan 10-24 Wales
A bit sloppy from Wales as Freddie Thomas is offside in midfield, giving Japan a penalty which they kick deep near the Welsh 22.
Pressure back on for the visitors.

Macleod does so well there, that penalty has brought the momentum back to Wales.

That's what Josh Macleod is all about.
The Wales openside flanker goes foraging on the floor at a ruck and earns his team a precious penalty.
Dan Edwards will have a kick at goal, some 40m out, to the right.

Since half-time the game's gone a bit loose.
Japan look good with the ball, they had a couple of chances and the bounce just didn't go their way.
Wales need to tidy up now, little things like that make the difference.
Japan 10-21 Wales
And breathe. Japan have a lineout on halfway.
Wales need some control.

The Japanese attack is looking more threatening.
Johnny Williams did well to get a hand in because if Japan take that ball, they are under the sticks.
Japan 10-21 Wales
It's getting slightly panicky for Wales, with Japan upping the tempo and putting their opponents under pressure.
A knock-on in the 22 gives the visitors a reprieve, but they need to start playing this game back in Japan's half.

Japan will be remembering last week, when in the second half when they raised their tempo, and played a bit more rugby, they tore Wales apart.

Wales lose the lineout. Worrying signs already in this second half.
But the next defensive phases are strong, they turn the ball over and Ben Thomas clears.

Hopefully Wales have learnt from last week, they need to keep going on what's worked for them in the first half.
The scrum's been strong, and the maul has been working for them, so concentrate on those things and we should be alright.
Japan 10-21 Wales
A shame for Wales as Nicky Smith is forced off injured.
Gareth Thomas, a very able deputy, comes on.
Japan 10-21 Wales
A let-off for Wales. Dewi Lake takes a risk throwing to the back, the ball bounces loose but Japan concede a penalty as Aaron Wainwright is tackled off the ball.
A chance for Wales to clear.

James Hook
Former Wales fly-half on BBC Radio Wales
That's a really good cover tackle from Aaron Wainwright, but that's a warning sign for Wales.
We didn't see too much of that in the first half.
Japan 10-21 Wales
Wales will be hoping history doesn't repeat itself in this second half.
Japan's handling is slicker, the tempo is quicker and they're on top in these early exchanges.
Wing Kippei Ishida is tackled into touch and Wales have some respite.
Prop Nicky Smith is down receiving treatment but will continue for now.
Japan 10-21 Wales
Alex Mann is penalised for pinning down Japan captain Michael Leitch off the ball.
Japan kick to touch in the Wales half, secure the lineout and are on the attack right away.

There are seven Welsh replacements "warming up" on the field with uncapped Ospreys wing Kelean Giles not there.
It looks like Giles will finally win his first cap nine years after being named in a Wales squad.
Giles is on for Josh Adams at the start of the second half.
Japan 10-21 Wales
The second half is under way, with Dan Edwards taking kick-off for Wales.
A huge 40 minutes for the tourists as they chase a first Test win for nearly two years.
