Saturday's practice session at the Suzuka circuit would see the drivers come out with the track covered by clouds and with rain falling. There were several places on the circuit where there was rivers of water coming across the track. It was expected that the race would be run under dry conditions but full wets was the tyre of necessity for this session. Alguersuari was first out, followed by di Grassi, Yamamoto, Glock and Senna. More drivers were coming out including Massa, Kobayashi, and Schumacher, Webber, Rubens. Alonso had also come out but would return to his pit after a slow lap. Button was now out on the track along with Petrov and Trulli.

Drivers were reporting their concerns over aquaplaning while Button would complete a second lap returning to his pit. Glock would spin at the Spoon curve but was able to continue. The rain continued to fall and was even heavier. With nearly twenty minutes of the session completed no times had been set. Everyone was back in their pits except Alguersuari who would eventually pit without setting a time. Rubens was in his pit looking very relaxed out of his car. Hamilton would come out on an installation lap. He would start a second lap as Alguersuari and Glock returned to the track. Button would also return while Alguersuari would have a half spin but was able to continue as he went across the grass.

Both McLaren's would pit as Alguersuari set a 1m:58.016 to record the first time. Glock would join him with a 2m:07.497. The conditions look really terrible as Alguersuari improved with a 1m:55.902. Glock would pit followed by Alguersuari. With twenty five minutes remaining the track was again empty as the conditions really got far worse. Nico Hulkenberg was out of his car talking to Sam Michael. Buemi was the next driver to come out and he would spin coming out of the final chicane. He would pit while Kubica would leave the pit lane with just over ten minutes remaining. He would pit after a slow lap. There were still rivers of water running down the track with six minutes remaining. Ross Brawn would say that the conditions were just too dangerous. Hamilton would return to the track running very slowly. He would pit after one lap leaving the track empty again.

But once again it would be Alguersuari and Buemi who would return to the track. They would complete a slow lap and would perform a practice start on the grid and would then return to the pits. The session would come to an end with just two times set while Rubens despite getting into his car did not come out. With reports having the terrible conditions remaining for the rest of the day there was now concerns as to how qualifying would be run.
