Button capped off a superb weekend in his adopted homeland after dominating free practice and qualifying second, as he ended Vettelâ€™s run of wins at the Honda-owned circuit to win his first Japanese Grand Prix.
â€œIt gives us as a team a lot of motivation,â€ Button said. â€œIt is good to see three different cars within three seconds, it shows how competitive F1 is at the moment.
â€œI need to say a big thanks to the team for the improvements we had over the last few races and today they were impeccable, congratulations to them.â€
Vettel became the youngest double world champion after his third place was more than enough to secure back-to-back world driversâ€™ championships with four races to spare.
â€œA strong result again today to win the championship here, itâ€™s fantastic,â€ Vettel said. â€œThere are so many things you want to say in this moment but itâ€™s hard to remember all of them, so I am just so thankful to everyone in the team.
â€œWe have so many people here at the track and at Milton Keynes, day in and day out, not only Friday, but also Saturday and Sunday and Monday to Friday, every day pushing hard, fighting hard for points and fighting for the championship.â€
Mark Webber was fourth for Red Bull ahead of McLarenâ€™s Lewis Hamilton and Mercedesâ€™ Michael Schumacher, who was sixth.
Felipe Massa finished seventh behind his former Ferrari team-mate, with Sauberâ€™s Sergio PÃ©rez eighth ahead of Renaultâ€™s Vitaly Petrov.
Mercedesâ€™ Nico Rosberg produced a stunning drive to round out the top 10, despite starting 23rd on the grid after a hydraulic problem prevented him from qualifying,
Vettel chopped off Button at the start as the McLaren driver got a better drive off the line, crowding the Briton on to the grass and allowing Lewis Hamilton to sweep past into second place at the first corner.
â€œHe’s got to get a penalty for that,â€ screamed Button to his team later in the lap, but despite investigating, stewards decided to take â€œno further actionâ€ over the move.
Hamilton picked up a puncture on lap eight, forcing him to release Button before recovering for a fresh set of tyres and dropping him to fourth behind Massa.
Vettel pitted at the end of lap nine for another set of option tyres before Button, Alonso and Webber all followed suit on lap 10 – Button was clearly able to look after the blistering soft tyres better than his rivals.
After gaining over a second in time, Button emerged from his second pit-stop ahead of Vettel, and quickly set about opening an advantage.
Vettel was able to close up again as the safety car came out to allow marshals to clear debris from the track, including part of Massaâ€™s front wing after yet another collision this season with Hamilton – but this time the 2008 world champion avoided any penalty.
With Vettel in traffic after the safety car, he pitted early to switch to the medium compound tyres for the rest of the race, Button emerged still ahead after his stop, but Alonso managed to get a jump on the German as he struggled with the slower tyres.
After initially pressurising Alonso, Vettel was told to cool it by his team. The German was happy to secure another podium, and his second successive world championship.
Schumacher enjoyed an eventful race, which saw him lead for the first time since the Japanese Grand Prix in 2006 as he ran a very long second stint, coming out of his final stop ahead of Massa.
