The second Friday practice for the 2010 Japanese Grand Prix would get underway with a rush of drivers leaving the pit lane. Both Williams drivers, Nico Hulkenberg and Rubens Barrichello would take to the track early on with Nico putting himself at the top of the times with a 1m:33.800 after six minutes of the session. As the session continued Nico would drop to third with Alonso fastest with a lap time of 1m:33.159 ahead of Petrov, Nico, Kubica and Rubens.

Nico would return to his pit after six laps on the track. Nico would report to his engineer that his car was bouncing and bottoming out much more than in the morning session. Rubens had also pitted but he would return to the track after twenty two minutes of the session, looking to improve from his current twelfth. Fastest at this time was Vettel with a time of 1m:32.501.

After forty five minutes of the session Nico had dropped to eighth and Rubens in tenth. Rubens's time was a 1m:33.564. Hamilton's crash in the first session would see his team only finish their repairs with the McLaren not ready to take to the track until there were just eight minutes left. Hamilton would complete just seven laps finishing thirteenth.

As the session drew to a close every driver with the exception of Rubens was back out on the circuit for their final runs. Rubens was having a engine related issue, which would limit his track time. Rubens would finish in fourteenth after completing just sixteen laps, compare to Nico's twenty six. Rubens was still in his garage as the session came to a close. Red Bull would continue to dominate with Vettel fastest with a lap of 1m:31.465 to be ahead of team-mate Webber. Kubica was in third Alonso fourth and Massa fifth. Button ended the day in sixth position with Petrov seventh and Schumacher eighth.

As for the AT&T Williams team it would be hard to draw any conclusions as to their form over Friday practice with Rubens problems in the second session limiting his track time. The problem with his car was a pneumatic leak that occurred towards the end of the session. It was also found that Nico had an electrical problem with his car during the session.
