The rest of the chasing pack all improved their jumps, but nowhere near enough to compete with Kraft and Johansson and Kobayashi had to settle for silver and bronze respectively.
Two riders to shine in the first jump were Dawid Kubacki and Junshiro Kobayashi, brother of Ryoyu but they faded away at the second attempt.
As the men prepare to move to Trondheim, Kraft has closed the gap on the Raw Air leaders.
He now trails Johansson, who is top of the standings, by 12.9 points, he is also now 14 points ahead of Kobayashi.
In the World Cup standings, Kraft is solidly in third place and is now just 18 points behind Kraft, who is currently in second.
