Tough American Johnson will come to Britain on December 1 to reignite his own world title credentials, after going the distance with WBC World heavyweight champion Vitali Klitschko in 2009.
Exciting unbeaten Fury expects 6ft 3in Johnson (28-2-1, 13 KOs) to be his hardest opponent to date and believes the fans will be in for a real treat.
"Johnson is just the kind of opponent that I want at this stage of my career. We needed a world class fighter and we have got one and when I take him apart the world will sit up and take notice," said Fury (19-0-0, 14 KOs).
"I'm not going around getting opponents out of graveyards, fighting guys well past their best like some other heavyweights in Britain. I'm taking on Kevin Johnson who has fought for a major world title and been the distance with Vitali Klitschko.
"I am getting closer to a shot at Klitschko myself and I'm going to show Vitali why he has to fight me because when I do a number on Johnson and get him out of there I'll have done a better job than Vitali did on him.
"I'm really looking forward to fighting again in Belfast, the support I get there is great and to bring such a big fight there is terrific for the fans. Johnson is going to be tough, he's a hard man but I'll be in the best shape of my life. The fans can expect fireworks, that's for sure."
Promoter Mick Hennessy says Johnson is going to be the perfect world class test for Fury at this stage of his career.
"Kevin Johnson has been there and done it and he wants another shot at the world title and he sees Tyson as the route to that, that's why he has taken the fight," said Hennessy.
"He's a very dangerous opponent, he's a clever boxer, he's never been stopped and he can punch so Tyson has his work cut out.
"But I believe that Tyson is the best heavyweight in the world and he'll show that again with the way he takes care of Johnson.
"Johnson has been asking for this fight for a long time and we have granted his wish unlike a lot of other fighters who have avoided him as he is a very dangerous fighter over 12 rounds."
Former world heavyweight title challenger Johnson is coming to Belfast full of confidence with his sights set on railroading Fury's world title aspirations.
"I'm excited about the opportunity to step into the ring with Tyson Fury," he said. "It's a fight that I've been looking to make for a long time. It's going to be the best American fighter against the best fighter in the UK.
"I give Tyson all the credit in the world for stepping up to the plate and taking the fight. This is the biggest fight of my career since my world title fight against Vitali Klitschko in 2009."
