On signing his deal, Johnson heaped praise on the City chairman Steve Lansdown for the backing he has given him so far.
He told the club's official website: "I am very happy to have signed this new deal.
"The chairman mentioned it to me in the close season and gave me something think about. He told me about his own ambitions and his ambitions for the football club and that he would like me to be a part of that.
"I was very excited at the time and it's been agreed. I'm honoured that the chairman has chosen me as the manager to see him through the next five years because he is a very ambitious chairman, and the club will be going places in the next five years."
