Sebastian Vettel convincingly won the Japanese Grand Prix to keep his slim title hopes alive but championship leader Jenson Button stayed in control.
Cool Button capitalised on an Adrian Sutil error to finish eighth, although a late safety car denied his Brawn team being crowned constructors' champions.
The Englishman now leads the title race from team-mate Rubens Barrichello, who came seventh in Japan, by 14 points.
Toyota's Jarno Trulli landed second at Suzuka ahead of Lewis Hamilton.
