Aoki Yasuo (青木 保夫) is a 3-D sculptor who always brings a sculpture of a SASUKE obstacle with him to the starting line. He has competed in thirteen SASUKE tournaments, but has never cleared the first obstacle, with his closest attempt at beating the first obstacle was in Sasuke 15 when he failed the jump to the landing platform on the Hurdle Jump. He, Harashima Masami, and Kuramochi Minoru are usually given consecutive starting positions.
Aoki was indirectly involved in a very bizarre incident in SASUKE 25. In the lottery to draw start positions before the tournament, he drew #48. Levi Meeuwenberg, who had drawn #39, slipped while on the Dome Steps and steadied himself using his hands, which is illegal. Meeuwenberg protested, however, claiming a mistranslation of the rules. He was granted a mulligan, which is not altogether unusual, but was given Aoki's bib; Meeuwenberg appears on the broadcast wearing #48. In the list of competitors aired before the Second Stage, Aoki was listed as #39. The explanation for the bib change was revealed in the Official SASUKE Book, as it is now known Aoki did not compete that tournament, though the reason for that is unknown.
Incredibly he was able to beat the first obstacle for the first time in any show on Viking 2. He however couldn't get pass the Loading Dock.
After Kasuga Toshiaki cleared the first obstacle, the Quad Steps, in SASUKE 39, he become the only competitor that competed for more than three times but never cleared the first obstacle.
