He claimed fifth place in the Brazilian Grand Prix to edge out his nearest challenger, Brazil's Felipe Massa - who actually won the race.
He becomes Britain's first world champion since Damon Hill 12 years ago.
But 23-year-old Hamilton left it late to claim the title.
He was lying sixth on the final lap, but the team to the gamble to put him on wet tyres and as the rain came down he took the chance to claim back the places he needed.
Hamilton was in tears before he had even climbed out of the car and struggled to find the words to thank the MacLaren team over the car radio.
Back in the pit lane the tears flowed again.
"It's impossible to put into words," he said.
"it's been such a long journey, I'm so thrilled to be able to do this for everyone."
And he paid tribute to his father Anthony, who had paced the MacLaren garage, unable to watch the final moments.
"Dad, you're the man," he said.
Felipe Massa could not hide his disappointment.
At the post-race news conference he said: "We're going to learn from this day.
"That's the way it is. I'm very emotional."
Sky's Chris Skudder said it was about as good as sport gets.
"We've seen some great sporting moments, " he said.
"But you couldn't have made it up. To overtake to win the championship with just 100 yards to go."
Before the race he must have feared a repeat of 12 months ago. Last year, in his first season in the sport, Hamilton let a 17 point lead slip in the final two races.
This season he has had to overcome dubious decisions, racist abuse and even accusations his driving style was too dangerous.
But he has matured from last season, and he will have learned from his mistakes in Japan.
He has wanted this moment ever since he introduced himself to McLaren team boss Ron Dennis at the Autosport awards, aged 10.
"I'm going to drive for your team one day", he told an amused Dennis.
Some 13 years later and Hamilton has proved his potential.
