As the Rugby World Cup pool stages head towards a thrilling finale on Sunday October 13, Telegraph Sport casts an eye over the goings-on in each pool.
We explain what each side needs to do to qualify for the quarter-finals, to be played on the weekend of October 19, as well as what a few of the weaker sides need to do to finish third in their pool and qualify automatically for the 2023 World Cup in France.
Despite Typhoon Habigis' impact to the schedule, there are still some crucial fixtures taking place this weekend.
Pool A is the complicated one. Japan will progress as Pool A winners if they beat Scotland on Sunday - that's for definite. If Japan lose to Scotland and Ireland beat Samoa with a bonus point, then Ireland will top the pool.
Ireland will qualify whatever happens if they can get a bonus-point win against Samoa on Saturday. Thanks to Scotland's bonus-point win against Russia on Wednesday, they will go through at Japan's expense - on head-to-head - if they beat the hosts in Yokohama and deny them a losing bonus point.
If Japan get a losing bonus point against Scotland, moving to 15 points, Scotland would have to get a winning bonus point to go through (on head-to-head). If Japan get a losing bonus point and a four-try bonus point (to move to 16 points) there is nothing Scotland can do even if they win both of their remaining matches with bonus points.
If Ireland beat Samoa without a bonus point on Saturday, there is a possibility that all three teams could end up on 15 points. The pool would then be decided by points difference, which is currently very tight.
This is, of course, as long as Typhoon Habigis does not derail the weekend's proceedings.
South Africa's big win against Canada on Tuesday secured them a place in the quarter-finals and, due to New Zealand's match against Italy being cancelled, South Africa will progress as runners-up in Pool B.
Neither Namibia nor Canada can finish third or qualify from the pool.
England's match against France has been cancelled due to the arrival of Typhoon Hagibis and, with both teams receiving two points from the 0-0 draw, Eddie Jones' men will progress as Pool C winners. France progress to the quarter-finals as runners-up in the pool.
The only pool that is seemingly unaffected by Typhoon Hagibis is Pool D. Wales' hard-fought win over Fiji has secured them a spot in the quarter-finals, and a win against Uruguay on Sunday will see them progress as Pool D winners. If Georgia beat Australia in both teams' final pool match, then Wales can afford to slip up against Uruguay and will still top the pool.
Australia will qualify for the quarter-finals if they beat Georgia on Friday. A win, too, will mean the Wallabies will top the pool if Wales fail to beat Uruguay.
Georgia will have to beat Australia to finish third in the pool.
Uruguay will have a chance to finish third if they beat Wales, but they might need a four-try bonus point.
