Damian Willemse will start for South Africa against Canada today - less than a week after arriving in Japan as a late injury replacement.

Full-back Willemse, who arrived on Thursday to replace Jesse Kriel, is one of 13 changes made by coach Rassie Erasmus for the World Cup Pool B match.

South Africa have a four-day turnaround after beating Italy 49-3 on Friday.

Only Springboks captain Siya Kolisi and centre Damian de Allende have retained their places.

Japanese society has a lot to teach us about respect. Trains are plastered with signs reminding travellers not to use their phones on-board and on match days there are announcements in English telling fans not to "cause any discomfort" for their fellow passengers.

The high value placed on respecting others has translated onto the pitch too. Teams have stayed out on the field after full-time to go round and bow to every side of the stadium, as is the Japanese custom when thanking someone.

And there's been plenty of respect between teams behind the scenes. After thrashing them 63-0, reigning champions New Zealand invited Canada into their dressing room for a few post-match beers.

You never quite know what you are going to get in Japan. It is never boring; and always fun.

For example, the weather seems impossible to predict - any given day could be a combination of perfect sunshine or torrential storms - while at breakfast one needs to be prepared to eat anything from rare beef to fish stew to donuts and cakes.

And for such polite and reserved people, the Japanese also absolutely love letting their hair down by getting stuck into good food and good drink - often in a karaoke booth.

With this being the first World Cup to be hosted in Asia, we've been asking the BBC team out in Japan to tell us what it is they love about the Land of the Rising Sun.

And we'd love your input too, get in touch at #bbcrugby to let us know what you've made of this tournament so far.

Victory over Canada will guarantee South Africa a place in the quarter-finals, unless Italy stun New Zealand in their final pool match.

The Springboks lost their opening game of the tournament to the All Blacks, but have since beaten Namibia and Italy.

"This match is just as important as the three that we have already played," said Erasmus.

"It has the same number of log points available and the same impact on our chances of qualifying. We have to now complete the job.

"If you look at the phases Canada produced against Italy [in a 48-7 defeat] and how they botched a few tries - they could've scored four or five really good tries.

"I've played against them and this team I've picked will know they are in for a physical battle."

That said...

Comprehensively beaten by Italy and having failed to register a point against New Zealand, it would be a monumental upset if Canada were to beat two-time champions South Africa.

The North Americans have scored just one try so far this tournament and are 150-1 shots with most bookmakers to win in Kobe...

But if this tournament has taught us anything, it's to expect the unexpected.
