Absolute power from South Africa. Fair play to Japan, they tried to stay in the scrummage but Faf de Klerk passed it to Mapimpi, it was man-on-man, but unfortunately the man in front of him, Tamura, he was absolutely straight through him and it was an easy run-in. Disastrous start from Japan.

Japan are just so creative in everything they do. A short, well-worked line-out sees the cherry and whites float it left.

Yu Tamura then looks to switch the play with a looping pass, but it slips forward and that'll be a South Africa put-in 25 metres from the Japan line.

Brave - and perhaps optimistic - rugby from Japan in the opening minute, looking for a dinked cross-field kick into the path of Kotaro Matsushima inside his own 22.

The ball goes loose but the Brave Blossoms recover it.

Here. We. Go.

There is a huge amount of belief in that Japanese squad so the preparation going into this game is going to be very different for the South Africans, they genuinely know if they don't get it right the Japanese will turn them over.

You know what you are going to get out of South Africa. If Japan have somehow summoned the energy to play another 60, 70 minutes like they did against Scotland then they have a chance, but it will take a monumental effort.

I think Japan are going to score two or three tries.

Captain Siya Kolisi leads his side in belting out the South African anthem. And now we're moments away from kick-off...

Tears in the eyes of the Japanese players during an emotional anthem. What a moment for them - a first ever World Cup quarter-final.

And they don't want the dream to end here.

Japan make one injury-enforced change as Ryohei Yamanaka slots in at full-back in place of Will Tupou. Springboks coach Rassie Erasmus has recalled front-rowers Tendai Mtawarira and Bongi Mbonambi in the hope their extra muscle up front will be enough to overpower the hosts.

Japan: Yamanaka; Matsushima, Lafaele, Nakamura, Fukuoka; Tamura, Nagare; Inagaki, Horie, Koo, Thompson, Moore, Leitch (c), Labuschagne, Himeno.

Replacements: Sakate, Nakajima, Ai Valu, Van der Walt, Lelei Mafi, Tanaka, Matsuda, Lava Lemeki.

South Africa: Le Roux: Kolbe, Am, De Allende, Mapimpi; Pollard, De Klerk, Mtawarira, Mbonambi, Malherbe, Etzebeth, De Jager, Kolisi (c), Du Toit, Vermeulen.

Replacements: Marx, Kitschoff, Koch, Snyman, Mostert, Louw, H Jantjies, Steyn.

As with all the quarter-finals, there will be a moment's pause to remember those who lost their lives during Typhoon Hagibis last weekend.

South African players must be fed up of being quizzed about that shock defeat by Japan four years ago in their media outings this week.

Fly-half Handre Pollard insists the experiences of 2015 will have no bearing on the clash in Tokyo.

"Four years ago was a complete different story," he said. "Different South African side, different World Cup, different place.

"A lot has happened in the meantime. The guys who were part of that 2015 side certainly learnt from the mistakes we made, and hopefully we can improve on that in this play-off series.

"But it's not a big focus. We want to play our best rugby and win, by one point or whatever - we've just got to win."

That is some entrance.

Japan and South Africa make their way on to the pitch in Tokyo to fanatical hollering from the home crowd - it's a sea of cherry and white, with a sprinkling of green.

The starting XV has just been announced and captain Michael Leitch got the loudest response by far. It wasn't a cheer, though. Instead, Japan fans shout Leeeeeeeeiiiiiiiiitch every time they see him.

Wing Kenki Fukuoka also got a lot of love, as did head coach Jamie Joseph.

Japan have already won for me in this tournament, particularly in the face of that disastrous typhoon last weekend. It might be the last roll of the dice from them in this tournament but if they play the way they play, stick to what they're good at, they could give the South Africans a game.

I feel like we all need this game in our workplace...

Japan have been praised for their fast, flowing rugby this tournament but South Africa have their own pocket rocket who can turn a game in an instant.

"Dynamite comes in small packages!" said diminutive Springbok wing Cheslin Kolbe, who averaged 12.8 metres per carry in the pool stage, the best rate of any player to make 10 or more.

"We all have something special we can contribute to our various teams. Both the Japan wingers are currently playing really phenomenal rugby. They've been on good form.

"Kenki Fukuoka is a very good player, he's got a lot of speed, he's really powerful and explosive - a really good all-round player. Kotaro Matsushima loves to run with the ball and just have a lot of freedom.

"I love to have ball in general play and having one-on-one opportunities within a game and create as many opportunities not for myself but players around me.

"I enjoy running with the ball in hand and whenever I do get opportunities, I'll make sure I keep on having fun."

A huge roar as Japan head back into the tunnel led by captain Michael Leitch, who is a hero round these parts.

Gotta love that arrowhead formation.
