Kadono started the final round of the season in equal 14th in the overall slopestyle World Cup standings after a 14th in Copper Mountain and 12th at Spindleruv Mlyn.
However, as the weather and heavy fog once again caused disruption at the Spanish resort, victory for Kadono saw him jump up all the way to first for the overall World Cup.
Kadono claimed his maiden World Cup win with a score of 94.00 from his second run while his first effort of 88.00 would have also seen him end victorious.
Maxence Parrot of Canada finished second with a first-run effort of 85.50 while Brit Morgan, making only his fourth World Cup start and third in slopestyle, placed third.
Morgan scored 78.50 on his first run for third, his second effort was 27.75, with another Canadian Jonathan Versteeg in fourth with a total of 72.50 first time out.
Kadono ended the season with 1400 points for the slopestyle World Cup title with Sven Thorgren, who finished ninth in Sierra Nevada, placed second overall with 1250.
Torstein Horgmo was third with 1220, Parrot fourth with 1200, Stale Sandbech fifth with 1120 and Morgan, who finished fifth in Copper Mountain and 34th at Spindleruv Mlyn, sixth with 1072.
And, while the men's event was completed in Sierra Nevada, the women's had to be cancelled due to time and safety issues with no title awarded.
