The Springboks cannot have any doubts in their minds this weekend or they will get swept away by a Japanese tsunami.
Against Japan in a World Cup knockout match, the slightest show of weakness or lack of accuracy and commitment could spell disaster.
We have, of course, been here before with the Brave Blossoms.
The shock in Brighton four years ago still have mense paaping despite the Bokke beating their hosts in warm-up ahead of the tournament.
Since that meeting five weeks ago, Japan have gone on to win all four of their pool games.
They even stunned the Irish, ranked No.1 in the world coming in the event, to top the group and book a clash against the Bokke.

I doubt anyone expected that, with Bok fans having already preparing themselves with a showdown against Ireland.
Even the way Japan have been playing has changed perceptions and the Bokke will have face a team riding a tsunami of home and global support.
The crazy and impressive thing about Japanese rugby is just how quickly it has evolved to this point.
Before Eddie Jones arrived in the Land of the Rising Sun, Japanese rugby was all about effort and hard work.
If you can remember what a huge deal Kamp Staaldraad was, that’s nothing compared to what Japanese players had to go through.
There are stories of how school teams went through hardcore training regimes called “bloody urine”.
Yeah. If you don’t piss blood, you aren’t gyming hard enough.

While it might seem cartoonish, like Dragon Ball’s “hyperbolic chamber” for Saiyans to train in, the principle of Doryoku is an everyday idea for Japanese.
It means effort, passion, sacrifice, bravery, will, inspiration and many other good qualities if the word didn’t encompass so many ideas.
I guess, it’s similar to translating “gees”. It’s not just “spirit”. It’s more than that.
It’s World Cup knockout rugby and gees must trump Doryoku or Brighton will look like brighter days.
