The 17th Competition, official name: SASUKE2006秋 (literally SASUKE 2006 Fall) was a historic tournament in the history of SASUKE as Nagano Makoto became only the second man to ever achieve kanzenseiha. The First Stage had two new obstacles added, the Maruta Zaka and the Circle Slider. The time limit was only 85 seconds, the lowest since SASUKE 13. Preliminary trials were held for this tournament. Preliminaries included the bus tour trial (one representative), SASUKE 17 trials (eight representatives), professionals trial (2 representatives), and Taiwan preliminaries (one representative). Leading the qualifiers were Adachi Yūta and Li En Zhi, who both cleared the First Stage. Adachi would even clear the Second Stage but failed the Third Stage's Body Prop. Takeda Toshihiro was once again denied a spot in the Final Stage when he failed the jump from the Pipe Slider. Nagasaki Shunsuke became the youngest person ever to make the Final Stage at 18 years old (tying Kawashima Takayuki) but timed out on the Tsuna Nobori. However it was All-Star Nagano Makoto who stole the show, blazing through all the obstacles and defeating the Final Stage with 2.56 seconds left.
