Lance Stroll: "Despite the wet weather today, we were able to learn some things here and there on the track. Tomorrow will be a complete reset, with it expected to be dry, although there is still a chance of rain on Sunday. If the conditions are like this in the race, then what we have learned today will definitely come in handy. Either way, I am loving being back in Japan; the energy is great and the circuit is fantastic, even in these conditions."

Sebastian Vettel: "All the banners in the grandstands and the fans around the circuit make it feel like the closest thing to a German Grand Prix without the German flags! It is great to see so much support. Out on track, the grip was not great, but it was good fun - it is still a great track, even if it is wet, and I enjoyed myself. Obviously, it was all about being out at the right time if you wanted to set a competitive lap-time - but that was not the most important thing for us today. There is probably not much we can carry over into tomorrow, when it is expected to be dry - but we were still able to test some things, especially in the second session, and they might give us some added direction."
