Only one result can stop Sebastian Vettel from winning the drivers’ championship on Sunday.
Red Bull can also claim the teams’ title but whether they do is not entirely in their hands.
Here’s where they need to finish to claim the championships on Sunday.
How Vettel can win the drivers’ championship
This one is easy. The only way Vettel can fail to win the championship on Sunday is if Jenson Button wins the race and Vettel does not finish in the top ten.
Any other result means Vettel will retain his title.
How Red Bull can win the constructors’ championship
Red Bull need get both their cars home in the upper reaches of the points to be able to win the constructors’ title in the Japanese Grand Prix.
They will be champions if they extend their lead over McLaren by 34 points.
Naturally their best chance of doing that is with a one-two finish. However if the McLarens finish higher than sixth and tenth, or seventh and ninth, Red Bull won’t take the title on Sunday.
If Red Bull finish first and third they need the McLarens to do no better than eighth and ninth. Red Bull could also win the title with first and fourth or first and fifth again depending on how well the McLarens do.
So despite Red Bull’s crushing form they are not likely to win the championship just yet unless McLaren suffer some kind of misfortune.
