->''"From the Land of the Rising Sun, one hundred determined athletes have accepted the challenge to become...'''Ninja Warrior!''' Divided into four extreme stages, competitors must face the ultimate test of strength and will, in their quest to become champion. Many are called, few are chosen. Now, let's find out who's tough enough to become the next...'''Ninja Warrior!'''"''
-->--'''OpeningNarration'' of ''Ninja Warrior''

''Ninja Warrior'' serves as the American title of ''Sasuke'', a Japanese sports entertainment program -- no, not that kind of [[ProfessionalWrestling sports entertainment]] -- made famous through Creator/G4TV's Americanization. ''Ninja Warrior'' has grown in popularity thanks specifically to its heightened exposure via American television, it even airs regularly in Australia on Creator/{{SBS2}}. G4 would continue to air ''Ninja Warrior'' in the US through 2013.

At its core, ''Sasuke'' works like an obstacle course [[PlatformHell with the difficulty knob turned up to "Nightmare Mode" before getting broken off]]. A competitor gets one try at a [[NoDamageRun perfect run]], and if they go off-course on any obstacle or [[TimedMission run out of time]] on timed segments, they don't get another shot until the next competition. ''Sasuke'' eventually turned into a national phenomenon in Japan, where regulars and champions from the course get near-instant recognition. A total of thirty-one competitions -- about two per year -- have happened since the show's inception.

The ''Sasuke'' course sits at the base of Midoriyama, regardless of weather conditions; competitors have to learn how to adjust to extreme heat, cold, or rain if they hope to beat the course. Each competition traditionally begins in the afternoon, then continues for as long as it takes all one hundred competitors to either fail or complete the course. The individual stages and obstacles can change from one tournament to the other, but the general purposes of each stage remain the same:

* In Stage 1, competitors have to clear obstacles focused on testing speed and agility within a set time limit.
* In Stage 2, competitors have to clear obstacles focused on testing strength and endurance -- especially upper body strength -- within a set time limit.
* Stage 3 has no timer thanks to the obstacles focusing more on a competitor's overall strength. The last three obstacles don't have a place to stop and relax, which further ratchets up the challenge factor.
* Stage 4, the last stage, generally works the same no matter what: any competitor lucky enough to get this far must ascend to the top of a large tower within a ''very'' stringent time limit. One version features a two-stage climb 75 feet using a spider-wall method for the first half and an open rope climb the rest of the way. Another version challenges competitors to make a straight-up fifty-foot rope climb. A third version replaces the Spider Climb with a rope ladder. A fourth version of this stage -- first seen in the 27th competition -- reduces the tower in height to 66 feet and brings a rope climb similar to the first version of Stage 4 back. A higher 75 feet high variation of the fourth version was used briefly in the 28th competition, but was replaced by a 78 feet variation of the Spider Climb/Rope Climb version in the next competition.

Each stage, including the final stage, ends in one of two ways: a competitor fails via falling off an obstacle or not finishing in time or failing via disqualification on certain obstacles[[note]]Cannot use hands on Slack Ladder or Dancing Stones. Also, Spider Walk and its variants must be done barehanded, which comes after Chain Reaction. Chain Reaction required gloves for safety reasons.[[/note]], or they clear the stage and hits the trigger button (or crosses a finish line) at the end of the stage. A competitor could technically clear every obstacle during a stage and ''still'' fail the run because they didn't hit the trigger in time. (In one case, the competitor didn't even '''know''' about the trigger.)

Out of the 32 competitions (3,200 attempts) to date, only '''four men''' have defeated the entire course (a success rate of 0.125%). [[spoiler:Yuuji Urushihara became the first man to beat the course twice when he completed the course during the 27th competition.]] In one competition, a half-dozen competitors made it to the final stage -- only for each one to systematically fail. In another, thanks to the redesigned course, ''no one'' made it past level 2.

''Sasuke'' allows women to compete, and only one woman has ever completed Stage 1 -- but the all-female ''Kunoichi'' gives women their own spotlight. ''Kunoichi'' follows the same rules as ''Sasuke'' -- and even films at the same location -- but it occurs less frequently (only eight competitions have occured to date, which averages out to one per year) and uses obstacles that focus more on balance and speed. Out of the eight competitions (800 attempts), one woman -- Ayako Miyake -- completed the entire course '''[[CrowningMomentOfAwesome three times in a row]]''', and two other women have also finished the entire course (both accomplished the feat during the 8th competition).

In 2007, G4 held an "American Ninja Challenge" and chose the best competitors from this challenge to try out for ''Sasuke'''s 19th competition. From then on, G4 would run a new "Ninja Challenge" that coincides with upcoming ''Sasuke'' competitions. The popularity of the contest eventually led [=G4=] to film the first-ever ''Series/AmericanNinjaWarrior'', an all-American edition of the competition. [=G4=] filmed this competition in Japan on the ''Sasuke'' course, but limited the competition to ten finalists. The eight-part special, which covered both the tryouts and the actual competition in Japan, premiered in December 2009.

In later years, the show has worked like a ''Series/{{Survivor}}''-type reality show, with three teams of five men competing against each other to receive a shot to compete at the actual ''Sasuke'' competition. Then, in 2012, ''ANW'' took on a new format for its fourth season. Competitors now try out in regionals across the county to earn a shot at the finals in Las Vegas, where a fully complete ''Sasuke'' course has been created for the American contestants. The finals are similar to the traditional ''Sasuke'' tournaments, with a full list of 100 competitors taking a shot at the four-stage course, and a cash prize for a final reward. This new format has continued through to the present seasons.

Meanwhile, back in Japan, ''Sasuke'' went on a long hiatus in Japan following the 27th tournament, due to the bankruptcy of Monster9, the original production company. After a year-and-a-half long wait, TBS revived the competition for 28th tournament in December 2012 and the 29th tournament in June 2013 under the title of ''SASUKE RISING''. The 30th tournament, which aired in July 2014, broke the twice-a-year pattern in favor of an annual one. By this time, and shortly before the network itself disappeared from the airwaves, ''American Ninja Warrior'' [[ChannelHop moved from]] G4 to {{Creator/NBC}}, with repeats on the Esquire Network.

''SASUKE RISING 31'' aired in July 2015.

Do not confuse ''Sasuke'' with the character Sasuke from {{Naruto}}.[[note]]Fun fact: Both narrators of ''Ninja Warrior/Sasuke'' (Creator/KazuhikoInoue & Creator/DaveWittenberg) are the Japanese and English voices of Kakashi on that same series.[[/note]]
!! ''Ninja Warrior'' / ''Sasuke'' contains examples of the following tropes:
* AccentUponTheWrongSyllable: Shunsuke Nagasaki's name is continually pronounced "Shun-soo-kay" by Creator/DaveWittenberg when it should be "Shun-skay". It's especially bizarre because others whose names are pronounced in a similar fashion are correctly pronounced.
** Similarly with Rie Komiya, who's first name routinely pronounced like "Rye" by the announcer, when it should be "ree-yay".
** What makes this really strange is that Wittenberg is an anime voice actor, so you would think he would be used to Japanese pronunciations.
* ActionMom: Chie Nishimura, who returns later in Kunoichi, making it to the third stage, showing even as a housewife, she's still got it.
* AsLongAsItSoundsForeign / DepartmentOfRedundancyDepartment: The American narration calls it "Mt. Midoriyama"; the Japanese suffix ''-yama'' means "mountain". So the narrator is in essence saying "Mount Midori Mountain".
** Channel guides list the Kunoichi competitions as ''Kunoichi Women's''. A kunoichi is the term for a female ninja.
* AwesomenessByAnalysis / BadassBookworm: One guy overcame the Warped Wall obstacle (basically a wall curved outward) by studying tapes of it and writing a trigonometric equation.
** Another one made a to-scale mock-up of the course and did impressively well; he only ran out of time on the last rope climb.
* BadassAdorable: Ayako Miyake is really ''really'' cute and has also won Kunoichi three times, consecutively. Yuko Mizuno, Rena Higashi, and Rie Komiya also count.
* BadassBystander: Each and every one of the "Ninja Warrior All-Stars", whose professions run the gamut from fishermen to government employees to gas station managers. Only Toshihiro Takeda, a firefighter, is in a profession that people perceive as having to regularly deal with the kind of exertion that the obstacles provide.
** Not just the "All-Stars". In the 22nd tournament, only one man made it to Stage 4, and was the first person to do so since Makoto Nagano beat Stage 4. His name is Yuuji Urushihara. His profession? Shoe salesman.
*** He topped that in the 24th tournament by becoming the third man to ever beat the entire course. Then did it AGAIN in the 27th tournament by being the only man to do it twice.
* BadassFamily: Makoto Nagano's wife Asami competed in at least one run of ''Kunoichi'', and did quite well all things considered.
** American gymnasts and brothers Morgan and Paul Hamm competed twice. Paul made it to the end of the Second Stage while Morgan made it to the Third Stage.
* BadassGrandpa: He's not ''that'' old, but Kenjiro Ishimaru routinely makes it deep into the First Stage, being in his 50s and in excellent physical condition. Of course, fans of ''Series/KamenRiderDenO'' already knew how awesome he is.
* BlindIdiotTranslation: For some inexplicable reason, fireman Kouji Yamada is always referred to as Yasushi Yamada in the US broadcast.
* BoringFailureHero: Katsumi "Mr. Sasuke" Yamada is a notable subversion. Not only has he never managed to obtain Total Victory, but from the 14th tournament on he hasn't even managed to complete the first stage. The fact that he's focused his life completely on this (which cost him his job and his family) makes it all the more heartbreaking. Nevertheless, he is considered an All-Star and fans (as well as the other All-Stars) continue to cheer him on for him to one day reach on top of Midoriyama.
* [[BoringInvincibleHero Boring Invincible Heroine]]: Averted with Ayako Miyake, who has managed to win the Kunoichi competition 3 times consecutively. It helps that the obstacles are replaced with new (and more difficult) ones which makes the odds of winning even lower, let alone doing so twice. Even more so as [[ShockingElimination she was actually eliminated at the second stage in her fourth competition]]. [[invoked]]
* ContestWinnerCameo: Following the 2011 Tohoku earthquake and tsunami, G4 and ''Sasuke''[='s=] producers auctioned off a spot in the 27th tournament, with the proceeds going to the recovery efforts. The winner's run was shown, and though he failed on the First Stage he said he was honored to be there at all and glad that his money would be helping people.
* {{Determinator}}: A good way to tell an All-Star apart from the others is his determination to beat the course, and his crushing disappointment when he fails.
** Bunpei Shiratori is a textbook example in the 15th tournament: after falling victim to heat exhaustion, the officials were unsure if he could even perform in the First Stage without endangering his health; regardless, he went on to get all the way to the Third Stage with little issue.
** There was once a German competitor who made it to the third round and made it to the bar slide. However one side of the bar slid off, which unfortunately counted as disqualification (a rather controversial decision to some since it was more equipment failure then his own actions). Before this was announced however, the man actually ''tried'' to continue with the lopsided bar and made it to the end. Even was attempting to make the jump to the goal line before he was stopped.
* DistaffCounterpart: The ladies-only spin-off ''Kunoichi'' (''aka'' "Women of Ninja Warrior") has a different set of obstacles focusing on balance and agility instead of upper-body strength. As mentioned above, it's still very difficult.
* DeathCourse
* DownerEnding: Makoto Nagano fell less than ''two-tenths'' of a second short of completing Stage 4 in the 12th tournament. [[spoiler: But take heart. He eventually does win... three years later.]]
** [[spoiler:Sasuke 28 ends with the All-Stars, who have all announced their retirement, eliminated in Stage 1. Definitely a very sour note for them to end on]].
* EveryYearTheyFizzleOut: While it's a given that most of the competitors will probably fail at some point in Stage 3 (most superheroes would probably fail Stage 3), Katsumi Yamada is the poster boy of the trope. Every tournament the announcers discuss how he spends his life training, and every year he fails with a particularly bad stretch where he couldn't clear ''Stage 2''. Ever since Sasuke 14, he has been unable to complete '''''Stage 1'''''.
** Kazuhiko Akiyama would count, given his poor performances since his victory, but he suffers from chronic poor health and blindness, something the announcers bring up [[TheWoobie every time he competes since his victory]].
* FanService: The Kunoichi episodes. Come on, man. Come on.
** Female viewers have [[ShirtlessScene a lot to enjoy]] in the Sasuke episodes as well.
*** Perhaps the best example for [[MrFanservice female-centered]] FanService is Goku (No, not ''[[IThoughtItMeant that]]'' [[DragonBall Goku]]), a dancer who competes in only Tabi Boots and a Thong.
* FauxActionGirl: Yuko Mizuno; she's a very accomplished woman, but has suffered a lot of bad luck lately.
* GagDub: The Spanish dub is a pretty lame GagDub, with a lot of toilet humor and lame risqué jokes, that tries to capitalize on the smashing success that Takeshi's Castle had in Spain, in [[TheEighties the 80s]], with a similar (though much funnier) dub.
* GameBreakingBug: Every now-and-then some obstacle on the course comes apart, and causes the contestant to lose. The Barrel Roll of early competitions is possibly most notable for randomly falling off the tracks every now and then.
** Most recently, [[spoiler: Levi Meeuwenburg took on the second stage and jumped on a sliding bar obstacle when the bar jumped the track and dropped him into the water, disqualifying him.]]
** In the fourth women's tournament, one of the youngest competitors had what turned out to be one of the strongest Stage 1 runs... until she [[spoiler:slipped on a ''towel'' that had been accidentally left on the course by one of the production team, and fell into the water]]. This led to an outraged reaction when the producers made the disqualification stand and refused to allow her another run, on the grounds that she should have seen [[spoiler:the towel]] and avoided it.
** Makoto Nagano fell victim to one of these during Stage 1's slide jump. While the obstacle worked fine for everyone else, part of the rope attached to the slider was stuck on the outside railing, which caused the slider to stop too many feet away from the net, and made the jump towards the net impossibly long. After Nagano complained about the rope getting cut off, the officials took a second look, and agreed with him, thus disqualifying his attempt. The good news and bad news: Nagano has to do the ''entire course'' over again. [[spoiler: He succeeds]].
** In Sasuke 24, Kenji Takahashi was one of the competitors to make it to the final stage. During his climb, his safety line got tangled up and he was unable to continue until time eventually ran out.
* GameBreakingInjury: Shingo Yamamoto's shoulder could certainly qualify, as it's dislocated on him ''three times'' to date. Fellow All-Star Bunpei Shiratori has been unable to compete in recent tournaments because of an injury.
** Trampolinist Daisuke Nakata was the victim of a hit-and-run prior to Sasuke 17, leaving him with severely weakened grip strength. The effects are clearly seen when he attempts the third stage of the tournament, unable to make it past the Arm Rings, the first obstacle. He competes again in Sasuke 20, but he's unable to get past the Salmon Ladder.
** Drew Drechsel injured his knee during stage one in The finals of American Ninja Warrior 3 and had to drop out the rest of the tournament. He was the only one of the 10 finalists to not complete stage one.
* GameShow
* HeroicRROD: Many of the best contestants have the ability to make it all the way through, but get stuck on something that drains all the strength they have for the later obstacles.
* HoistByHisOwnPetard: Makoto Nagano on one occasion had the actually rather clever idea to grab the resting bar before the Devil's Swing to build up momentum. [[spoiler: Unfortunately, this only resulted in the obstacle repeatedly getting stuck behind the resting bar. And then [[UnwinnableByMistake when he tried to make the jump to the final obstacle, he accidentally knocked it out of reach and failed the course.]]]]
* JokeCharacter: "The Octopus", "The Butterfly", "Superman", and a cavalcade of comedians, {{cosplay}}ers, near-nudists, and humorous pro wrestlers. They usually don't get very far in Stage 1. Only twice did one of these guys both times comedian Kinnikun Nakayama manage to get to Stage 2. Subverted in SASUKE 31 with "Wreath Man", known by his real name: Ragivaru Anastase. He managed to power through the first stage, while wearing a wreath, and achieved the fastest time in the tournament, and made it up to Stage 3.
* LittleMissBadass: Rena Higashi was able to reach stage 3 of Kunoichi when she was 13!
* LostInTranslation: Hiroyuki Asaoka a teacher of the Japanese equivalent of elementary school is known by the alliterative pun nickname "Sasuke Sensei". In the English subtitles and narration, the nickname is changed to "Professor Ninja Warrior", which ruins the pun.
* LuckBasedMission: Even the best of the contestants will fail with one slight mistake.
* MarriedToTheJob: All-Star Katsumi Yamada; training for this ''is'' his job.
* MightyGlacier: Travis Schraeder can best be described as this; he's an extremely strong competitor and rarely loses the course by falling, but rarely manages to outrun the clock. He competed twice and timed out once. Oddly, in his first attempt, he posted the fastest Stage 1 clear.
* NoCelebritiesWereHarmed: A Barack Obama pastiche runs in the 22nd edition, complete with the crowd waving flags and chanting, "Yes, we can!". [[spoiler: He fails, and the announcer shouts out, "No, you can't!"]]
* {{No OSHA Compliance}}: It's mostly notable compared to the American Ninja Warrior counterpart. While the platforms have some padding it's often just carpeting and there are a few obstacles look worn and even involve sharp sheet metal edges. There have been instances of competitors falling off the course and onto the ground, usually due to an obstacle that requires a short run. The American courses have thick padding all around every platform, the obstacles themselves look newer (at least with a fresh coat of paint) and there are fewer obstacles involving sprints or running leaps.
* OverlyLongName: Jayawaira Umagirya Kankaanamuge Ranbindara. He was eliminated before the announcer had a chance to finish introducing him.
* OvershadowedByAwesome: With all the attention G4 gives to Levi Meuwenberg, Brian Orosco and others, it's easy to forget about Brett Sims, the winner of the first two American Ninja Warrior contests.
* PlatformHell: Definitely a RealLife example. Boy howdy! Only ''four'' people (Kazuhiko Akiyama in the 4th Competition, fan favorite Makoto Nagano in the 17th Competition, Yuuji Urushihara in the 24th and 27th Competition, and now Yusuke Morimoto) have completed the entire course in 31 competitions. If you include the ''Kunoichi'' competitions, with Satomi Kadoi, Rie Komiya (who couldn't get past the Halfpipe Attack in ''Sasuke''), and Ayako Miyake (who beat the ''Kunoichi'' course '''three times in a row'''), only seven people have ever completed the course.
* PositiveDiscrimination: Women can compete in both ''Sasuke'' and ''Kunoichi'', but men can only compete in the former.
* PromotedFanBoy: Those who made it to the tournament thanks to [=G4=]'s "American Ninja Challenge" tie-in.
** The best of these is Levi Meeuwenberg; in the 20th Competition, he got further than any other competitor..is ''immediately asked back'' for the next tournament.
* RetiredBadass: The All-Stars collectively retire from the competition after Sasuke 28, also referred to as Sasuke Rising.
** [[spoiler: TenMinuteRetirement: Makoto Nagano, Shingo Yamamoto and Toshihiro Takeda all return in Sasuke 29, though none are referred to as All-Stars since the title was retired.]]
* RegularCharacter: Yamamoto Shingo has run in all 31 ''Sasuke'' courses. He is the ''only'' competitor to do so.
* RiseToTheChallenge: Stage 4, which is best described as "climb tower ''really'' fast".
* SerialEscalation: If there is any stage or obstacle that is considered "too easy," it will be redesigned for the next tournament to make sure it is harder. In Sasuke 19 and 22, ''Stage 1'' eliminated all of the Ninja Warrior All-Stars.
** Not only did Sasuke 19 eliminate every All-Star in Stage 1, but 98 of the 100 competitors were eliminated on the stage. The two remaining competitors were both eliminated on the Salmon Ladder, an early but difficult Stage 2 obstacle.
** Sasuke 25 reveals the Double Salmon Ladder for Stage 2, where you transition from one set of pegs to another, and the Ultimate Cliffhanger in Stage 3. [[spoiler: Of the competitors who made it to the Cliffhanger, none are able to get beyond the first couple cliff transitions.]]
** Sasuke 28 goes one further, as Stage 3 adds the [[http://images2.wikia.nocookie.net/__cb20121223063442/sasukepedia/images/b/bb/Crazycliff2.jpg Crazy Cliffhanger]] (where, to reach the final cliff, a competitor must leap ''backwards'' and grab the miniscule ledge) ''and'' the [[http://images2.wikia.nocookie.net/__cb20121231062655/sasukepedia/images/9/99/Vlcsnap-2012-12-27-22h54m03s172.png Vertical Limit]] (a '''1 cm''' wide cliff that a competitor must navigate by grabbing both sides of the wall in a pincer grip. [[spoiler: All the competitors who make it to the Crazy Cliffhanger in SASUKE 28 fail on the jump ledge.]]
** Sasuke 28 also ratchets up the difficulty on the Salmon Ladder with a new variant: '''Swap''' Salmon Ladder. On this one, you have to zig-zag your way up, and the next pegs appear after you clear the last pegs, and unlike previous variants, if the bar lands sideways (One end on a higher rung than the other), you immediately get disqualified. To compensate for that, there is only one Unstable Bridge instead of two right after it.
** SASUKE 31 then made the Salmon Ladder even harder by introducing the ''Kudari Salmon Ladder'', where at first you just climb up the rungs as normal, before you swing over to another set of rungs where instead of going up, you go down the rungs to complete the obstacle. However, unlike previous Salmon Ladders, the up section and down section have their own separate bars, and instead of going directly to another obstacle without rest, you just swing over to a ramp.
* SpellMyNameWithAnS: Lee Yen Chee? Lee Yen Chi? Lee Enchi? Make up your mind, subtitles.
** And just to add to the confusion, the name pronunciation, and the name used on the Sasuke Wiki, is Li En Zhi, a fourth possibility.
** Worse yet, ''none'' of these are how the guy himself spells them: Lee En-Chih. (Li En Zhi is the traditional Chinese spelling but En-Chih is Taiwanese, which has a different spelling convention.)
** It's ''Wakky'', not Wacky. G4 doesn't seem to understand this.
* SpinOff: Until about the 8th Competition, the background is dotted with the emblems for ''[[Series/UnbeatableBanzuke Muscle Ranking]]''; ''Sasuke'' was initially run during that show, and was spun off.
* SpiritualSuccessor: ABC's ''[[Series/{{Wipeout2008}} Wipeout]]'' series was inspired by ''Ninja Warrior'' to the point where there was a lawsuit over the similarities between ''Wipeout'' and ''Sasuke'' but has fewer competitors, changes up the rules (falling off the course during a stage doesn't eliminate you, finishing last does; the first person to complete the last stage sets the pace that the other competitors must beat to win the competition), and uses "wacky" challenges instead of challenges meant to test one's physical limits. It also features another stark difference: whereas there's no advertised prize that a contestant can get (other than fame) for beating the entire course, Wipeout offers a $50,000 purse to the last person standing.
** The lack of a defined prize can be chalked up to Japan's stringent game show laws for civilians.
** In the UK, Creator/TheBBC cancelled Series/TotalWipeout - and {{ITV}} promptly commissioned Series/NinjaWarriorUK, thus reversing this trope.
* SuperStrength: You'll need as much upper-body as can be humanly summoned to beat Stage 3.
* TakeYourTime: Anyone that reaches Stage 3 has an unlimited amount of time to complete it. Considering the obstacles in this stage, this is ''very'' justified.
* TemptingFate: During one competition, the announcer mentions that the current competitor, [[spoiler: Makoto Nagano, barely ever made mistakes. Upon nearing the end of the course he forgets to kick off of the right part of the second to last obstacle and fails the course.]]
** In Sasuke 25, [[spoiler: right before Toshihiro Takeda takes on Stage 2, he smugly remarks how no one's failed at the new Double Salmon Ladder yet. Guess who's the first one that does.]]
* TenMinuteRetirement: Katsumi Yamada has remarked several times that he will stop competing, but he always seems to come back.
* TitleDrop: The Japanese announcer whenever one of the [=G4=] competitors is running the course.
** The Japanese name is Title Dropped a lot.
* TrailersAlwaysSpoil: The Sasuke 27 commercial shown Shingo Yamamoto failing a ''brand-new obstacle''.
* {{Transsexual}}: Hibari.
* TrueCompanions: It may be a competition, but the real opponent is the course rather than the other contestants. As a result, regulars like the All-Stars and the up-and-coming young guns have a great deal of respect for and camaraderie with each other. Shown rather touchingly by G4's special detailing Levi Meeuwenberg's training, where he spent a good deal of time with the All-Stars (Makoto Nagano in particular) and all of them were eager to let this person they barely knew into their homes and treat him as one of their own.
* WorldOfBadass: It's a show about people from all walks of life, from Olympic athletes to gas station attendants, running an insanely grueling Japanese obstacle course in the name of glory.
* YankTheDogsChain: The most glaring example is Katsumi Yamada, to the point where he actually quit competing for a tournament before having a HesBack moment
** Shingo Yamamoto manages to get to the third stage in the 23rd competition, the first time since the 17th competition and failed on the first obstacle. The reason? Remember when he dislocated his shoulder during his ascent on the Final Stage (See DownerEnding)? ''The same shoulder got dislocated only seconds after starting the third stage!''
*** For double the ouch factor, if you watch the replay, and know it's coming, you can ''actually see the moment his shoulder pops.''
** After making it through the qualifying round of ''American Ninja Warrior 2'' and going through the entire boot camp training regiment, Levi Meeuwenburg broke his wrist just before the Americans were set to head to Japan. He was still able to go, but he was unable to compete, prompting Adam Laplante [[PassingTheTorch to be brought in to take his place]].
* YouAreTooLate: Yuko Mizuno provides the worst example: she made it to the top of the tower in the final stage and hit the trigger mere moments after time ran out.
** This also happened to [[spoiler: Makoto Nagano in Sasuke 12, who was just 0.11 seconds short of defeating the Final Stage.]]
