Tottenham's 2-2 draw at Chelsea ensured the Foxes completed one of the greatest shocks in English football as they won the title for the first time in the club's 132-year history.
Leicester finished 14th, just six points above the relegation zone, at the end of last season but Ranieri's 5,000-1 shots are now seven points clear at the top and cannot be caught with two games left.
It is also Ranieri's first top-flight triumph in his managerial career and the 64-year-old admits emotions were running high when the full-time whistle blew at Stamford Bridge.
"The emotion was at the maximum level," Ranieri told Sky Sports News.
"It means the job is good
I am very, very happy now because maybe if I won this title at the beginning of my career maybe I would forget.
"Now I am an old man I can feel it much better."
Ranieri had been visiting his 96-year-old mother in Rome on Monday but landed at East Midlands airport in time to return home and watch Tottenham's draw.
Leicester's astonishing achievement will also bring Champions League football next season and Ranieri believes his side can now get even better.
"I said every time I am very happy for the fans, for the chairman and for all the Leicester community," Ranieri said.
"I don't know the secret
The players, the heart, the soul and how they play.
"My message to the fans is now to keep going, we want to improve a lot."
