Yamada Katsumi (山田 勝己) is a SASUKE competitor, a SASUKE All-Stars member and the leader of the Black Tigers who first competed in SASUKE 1, making it to the Second Stage but ultimately failing the Goren Hammer. He would go on to compete 26 more times, only missing SASUKE 13, SASUKE 25, and SASUKE 29 up until he was banned after SASUKE 30, and concentrated on training the Black Tigers, his team of younger athletes who he trains for SASUKE. His ban was lifted in SASUKE 33, which allowed to compete for the 20th anniversary. He officially retired after SASUKE 33.

Yamada has held many nicknames over the years, including "Mr. Banzuke", "The Nagiwa Terminator" and "The Black Tiger of Nagiwa", the inspiration for the name of his team. However his most famous nickname by far is "Mr. SASUKE", bestowed upon him because he was once thought to be the most likely competitor to clear all four stages. However, since SASUKE 12, he has been plagued with a string of First Stage failures due to his slow speed.

Personal History

He is particularly notable for his unusual devotion to SASUKE. He has sworn to retire several times after failing to complete the First Stage, but the draw of kanzenseiha is too great for him and he always manages to resurface again. Earlier on, he competed with the support of his family, but after he lost his job prior to the 5th competition because the factory where he worked (as a propane tank delivery driver) was closed, he did nothing but train for SASUKE, alienating his family in the process. He continues to train at his home even today. He has constructed several SASUKE obstacles and trains there daily.

He has held various jobs over the years, including delivering propane tanks and working in the steel industry, but he now devotes all his time to SASUKE training, only holding a part-time job. He has also vowed to retire several times (after SASUKE 8, SASUKE 17, and SASUKE 24 for example), but has only missed three tournaments. Out of the 27 tournaments he has participated in, he has cleared the First Stage ten times, the Second Stage four times and the Third Stage once. Though he showed good consistency in the early tournaments, since his comeback in SASUKE 14, he has never cleared the First Stage.

SASUKE History

Sasuke 3 final stage

Yamada Katsumi failing the Final Stage in SASUKE 3.

Yamada was one of the strongest competitors in the early competitions, showing his success in the first six tournaments. In the first tournament, he cleared the First Stage with just under six seconds remaining, but was tripped up by the Second Stage's Goren Hammer.

In a digested performance in SASUKE 2, he cleared the First Stage yet again, but struggled on the Spider Walk and failed there.

After this, Yamada went to building. To avenge his past failure, he created a homemade Spider Walk and homemade Pipe Slider to train on. His training paid off in SASUKE 3, where he not only beat his previous foe, but even cleared the Second Stage. In a debut performance in the Third Stage, he used an unorthodox but now vastly familiar cross technique on the Pipe Slider, and though at

first he had trouble, he soon became one of five to clear and reach the Final Stage. Yamada ran fourth, and not only did he have the best attempt, but was also the closest at the time to Kanzenseiha, missing the button by just tens of centimeters.

Following this, Yamada once again went to training, this time, with a crane. To practice for the Tsuna Nobori, he hooked up a rope to the crane 20 meters up and climbed it all the way to the top. SASUKE 4 is where he wore his first #100. Having to take two attempts at the Sosoritatsu Kabe, he cleared the First Stage with just under 7 seconds remaining. Having cleared the Second Stage with ease, Yamada faced the revamped Third Stage. He had a slight stumble on the Pole Jump, but the next one, the Propeller Untei, is where he had the most trouble. Failing to transfer to the second bar twice and to the final bar once, Yamada used up most of his grip strength. Having cleared the new Arm Bike like most with ease, Yamada came face to face with the new Cliffhanger. Like most others, Yamada struggled throughout, and by the time he transferred to the final ledge, he ran out of strength.

In SASUKE 5, the tournament after Akiyama Kazuhiko's kanzenseiha, Yamada once again wore the #100. When he attempted the Rolling Maruta, the log fell off the track towards the end, but Yamada barely missed touching the water. Nonetheless, clearing both the Jump Hang and Soritatsu Kabe, he became just the third competitor who advanced to the Second Stage. Yamada was thought to be a big favorite to clear the stage, but shocked everyone when he failed the revamped Spider Walk.

The day after, Yamada once again went to building, all within his property. Adding a Spider Walk, a Cliffhanger, and a Spider Climb, Yamada would train six hours a day. In SASUKE 6, he took his revenge on the Spider Walk and became the fifth and final person to clear the Second Stage, finishing out a perfect clear rate. In the Third Stage, Yamada got his revenge on the Cliffhanger. On the Pipe Slider, he cleared the final jump and landed on the goal mat, but he lost his balance and fell on the ground. The Final Stage was once again out of reach. From this tournament on, the water pits were extended to the sides to prevent this from happening again.

SASUKE 7 would see Yamada bring his wife and kids to watch him attempt the course. He reached the Soritatsu Kabe with 27 seconds remaining, which at that point, would mean clearing it first try. However, Yamada was turned back not once, but twice by the wall. By the time he had climbed up it, he just couldn't recover. He attempted to hurry, but time ran out on the Rope Climb. For the first time in his career, Yamada had been rejected from clearing the First Stage.

Prior to SASUKE 8, Yamada had announced that this tournament would be his last. It was all or nothing, do or die, Kanzenseiha or retirement. He took on the First Stage, he once again faced the Soritatsu Kabe at the same pace as last time. The slippery elements had taken a toll on everyone before him, and Yamada was no exception. Taking two attempts, he came nowhere near close to the top. Recoiling in disbelief, Yamada knew his time on the course was over. Taking the remainder of his time to check how slippery the wall was, he timed up on the very demon that would plague him for years. He took another attempt on the wall after time had expired, and although he was able to grab onto it, he let go. He gave it one more shot and climbed up it with ease. A bittersweet ending to Yamada's career, he attempted and cleared the Tarzan Jump and Rope Climb. In the end of it all, he had finally bowed out of the competition with his dream unrealized.

The next day, Yamada had completely torn down his homemade set, expecting to stay true to his word, but his love of SASUKE was too strong. He wrote a letter to the program's staff just two months before SASUKE 9, he was ready to return. Yamada was quick throughout the course, and although he took two tries once again on the Soritatsu Kabe, he was able to climb up it and clear the First Stage with ease. Once the Second Stage had begun, it was clear the problematic obstacle was the Spider Walk, and after seeing fellow competitor Nagano Makoto struggle through it, despite clearing, Yamada came up with an idea. He first put on adhesive spray to test it out, but that didn't stick much, so then he decided to put duct tape on his shoes to help stop from slipping off of the walls. When it came time to run, however, this plan failed, as he spent at least 17 seconds both taking the tape off of the shoes and applying adhesive spray to his hands. Seventeen seconds remained when he cleared past the Spider Walk, and due to his time loss in the first half, Yamada ran out of time on the second wall on the Wall Lifting.

In the 10th Competition, his friends before him had all failed, including big favorite Nagano, who ran right before Yamada, going out on the Jump Hang. Yamada, however, didn't let the new course phase him. He had been tripped up by the new Daasu Bridge, though he prevailed. Yamada cleared the Soritatsu Kabe on his first try, and although he took a lot of time on the new Tarzan Rope, he still cleared with under two seconds remaining. In the Second Stage, he opted only to spray his hands and got revenge on the Spider Walk that cost him time previously. He had slight trouble with the Wall Lifting and had to dive for the button, but he was still clear with 2.3 seconds left. Most of the Third Stage would be new for Yamada, and it showed. He first had a slight slip at the end of the Body Prop, and would begin to show fatigue during every obstacle after, but he prevailed onto the Pipe Slider. Once again using a reverse grip for both tracks, he made it to the final gap between him and a chance at glory. After multiple swings, Yamada jumped for the end, and although he had one foot successfully on, it wasn't enough. Yamada had dived back into the murky waters of Midoriyama. Having come so close to the Final Stage, a clearly emotional Yamada exited the pond. In an interview after his failure, these emotions prompted him to say one of the most famous lines in the history of the show, "俺には…、SASUKEしかないんですよ" which literally means, "For me, there is nothing else except SASUKE." This would be Yamada's last official attempt at the Third Stage.

In SASUKE 11, Yamada came back seemingly stronger than ever, everything went smoothly in the First Stage, clearing the Soritatsu Kabe on his first attempt and finishing the course with 4.5 seconds remaining. On the Second Stage, however, on the Balance Tank, he slipped up, landing with one leg on each side of the tank, a rather painful ending to Yamada's day.

In SASUKE 12, he easily made it through the First Stage, but he had a slow pace throughout, causing him to finish with less than a second remaining. In the Second Stage, Yamada admitted he was nervous about the Chain Reaction, so he brought his own work gloves to use instead of the ones traditionally provided. He cleared the nemesis that felled him previously, the Balance Tank, and cleared the stage with 3.55 seconds remaining. However, the gates would not open, and he was disqualified. The gloves are used for safety purposes during the Chain Reaction but must be taken off before attempting the Spider Walk. Yamada, however, forgot to remove the gloves, and was thus disqualified. Despite coming close a few times, this would be Yamada's final attempt at the Second Stage.

Yamada would compete in the SASUKE 13 Trials, aiming for a fast time, and was visibly frustrated when he finished in 12th place with a time of 10.58 seconds remaining. Despite earning a spot in SASUKE 13, Yamada decided not to compete in order to spend more time with his family, and even considered retiring. However, after watching the broadcast, he realized he "wasn't in the place that I had been fighting in for a long time".

Yamada would re-appear at SASUKE 14. He had a small slip up on the Cross Bridge, but managed to recover. He then shocked everyone by failing to get a good grip on the obstacle he'd cleared countless times before, the Jump Hang. This would not be the last of Yamada's woes.

First Stage failures

After SASUKE 14, Yamada had a long string of First Stage failures, most of which involved time outs. In SASUKE 15, he failed the Cross Bridge in a way similar to his failure in SASUKE 6, falling off the side of the obstacle just after clearing. He was close to falling on the Sandan Rolling Maruta and had another close call on the Reverse Fly in SASUKE 16, but time proved to be his biggest issue, as even though he cleared the Soritatsu Kabe in one shot, his slow pace from before saw him run out of time at the top of the Rope Climb. In an interview, he stated once again that "this is the end. Even if I fall, I've decided this is my last." However, still participating in events and starring in a commercial for a game, Yamada realized he had to overturn his retirement once again.

Yamada returned, wearing the #100 for the last time, in SASUKE 17. Although he was close to touching the water on the Jump Hang, he was still on good pace to clear had he cleared the Soritatsu Kabe on his first try, but was turned back three times on the wall, and by the time he had cleared it on his fourth try, the timer had already expired.

Yamada faced an entirely renewed First Stage in SASUKE 18, and despite getting all the way to the Rope Ladder, he could only begin climbing up as his slow pace throughout the course caused him to run out of time.

In the 19th tournament, Yamada showed great speed through the first two obstacles, but was hung up on the renewed Pole Maze. Combined with having to go back for a second attempt and being unable to move the pole once he went too far to go back, he spent around 75 seconds on the obstacle. He only had 20 seconds remaining when he cleared the obstacle, and with the warning buzzer sounding, Yamada was able to stick the landing on the Jumping Spider.

Before the milestone SASUKE 20, Yamada had injured his face during training. Despite this, he chose to compete, wearing the number #1999. He had initial difficulties getting the log on the Log Grip to go down the track, but was able to clear it nonetheless. He got revenge on the Pole Maze, but on the Jumping Spider, he was only able to stick inside the walls for a second before plummeting into the water, failing it twice in a row.

Yamada was not in his best condition in SASUKE 21, appearing with tape around his shoulders and legs. It appeared to be a case of how much he could worsen this condition, as he started limping after clearing the Rokudantobi. He got revenge on his previous foe, the Jumping Spider, and was slow throughout the Spider Walk section, but his condition worsened once he got off, practically falling down in pain. With no chance to clear, he returned to the Soritatsu Kabe, but was nowhere near close on either of his two attempts. He stated in an interview that he wanted to try again in his best condition.

Also in this tournament was Miyagi Takuya, who had won first place in that year's SASUKE Trials. He had trained with Yamada at his house before the tournament, and although he showed great speed, he was unable to stick the jump into the Jumping Spider.

In SASUKE 22, more pressure was added onto him than usual. Before the tournament, Yamada had received a letter from a child with leukemia, saying that he had "a bone marrow transplant in May. Having seen everyone do their best in Sasuke, I did my best. I want Yamada to make it to the Second Stage this time." Unfortunately, although he sped through the first three obstacles, he once again went down on the Jumping Spider after not getting a good enough jump into it.

Yamada once again trained someone in this tournament, this time in the form of actor Nakao Akiyoshi. In Nakao's previous attempt in SASUKE 20, he had fallen on the Jumping Spider, and unfortunately, he was once again unable to make the jump inside.

In SASUKE 23, Yamada would move easily through the first half of the course, beating the Jumping Spider which felled him previously. On the Half-Pipe Attack he would carry too much momentum, and almost go off the mat. On the Soritatsu Kabe he would take three attempts at the wall, each of them getting closer and closer to the top, and despite clearing it on his fourth, Yamada was already nearing the end of his run. When he reached the Slider Jump he slid down the track with a reverse grip, but similar to Nagano Makoto in SASUKE 22, he was unable to grab hold of the net and went in head first into Midoriyama's muddy swamp, making it his tenth consecutive First Stage defeat. Even if his attempt at the Slider Jump was a success, his run would've been in defeat by time. In his interview afterwards, Yamada announced that he would do his best in half a year, and that the next tournament he intends to be his last.

In SASUKE 24, Yamada had once again stated that if he didn't clear the 1st Stage, he would retire. He sped through the course, clearing his previous foe, the Jumping Spider, and the Half-Pipe Attack with relative ease. However, despite coming close multiple times and having both hands on the top at least once, Yamada was unable to scale the Soritatsu Kabe. Walking off the set in tears, his dream went unrealized.

Staying true to his word, Yamada did not appear in SASUKE 25. However, when SASUKE 26 came around, many All Stars were unable to appear. With Akiyama, Takeda, and Shiratori were all absent. To keep the name of the All Stars alive, he again wrote a letter to TBS, he was ready to return. Narrowly beating the Rolling Escargot which felled fellow All Star Yamamoto Shingo, he once again faced the Jumping Spider. It looked like he had stuck into the walls, but he slipped and jumped into the water. Although he fell quite early, this was the first time since the 10th competition that Yamada progressed the furthest of the All-Stars, as him and Nagano fell at the same spot.

Before SASUKE 27, Yamada finally raised his Soritatsu Kabe 20 cm higher, but he kept grasping the lower bar before scaling it. During the tournament he performed well through the first few obstacles. On the redesigned Half-Pipe Attack Yamada had to go back for a second try at the obstacle and he made the landing. Yamada once again struggled on the Soritatsu Kabe and timed out on the obstacle for the fifth time.

In SASUKE 28, Yamada's home course had not been maintained and he opted to tear it down. In the tournament, Yamada lost about 20 seconds on the Rolling Escargot and wound up having virtually no time left on the Ni Ren Soritatsu Kabe. He slipped on the first wall on his first try but climbed to the top as time ran out. In an all cut interview, he revealed that he injured his leg prior to the tournament, explaining why he was slow throughout his run.

Ιn a post SASUKE 28 exclusive interview, he stated that he will not retire yet and he will return when he feels he's ready.


For SASUKE 29, instead of competing, he formed a team of 4 newcomers to SASUKE; Yamamoto Hiroshige, Watanabe Yousuke, Okada Satoma, and Mizukawa Keishi. They were called the "Black Tigers" and wore #'s 47-50, respectively. However they all failed the First Stage.

Also, in that tournament, just for fun, Yamada ran the Third Stage (in the daytime) for the first time since SASUKE 10, but fell from the second ledge of the Crazy Cliffhanger. However if he competed in the actual tournament, he would be disqualified at the Iron Paddler as he used the metal supports to hold on and not fall in the water.

Yamada then competed in SASUKE 30, alongside the four other All-Stars, including Shiratori Bunpei. He wore his lowest start position to date, #2934 (He would have been #34 in a regular tournament.) Unfortunately, his run was completely cut though it was stated that he failed on the Ni Ren Soritatsu Kabe. It was later known that the reason he was cut was because he was banned from SASUKE because of a bad argument with Inui Masato. However, one of his protégés, Yamamoto Hiroshige, reached the Second Stage however failed when he was disqualified on the Swap Salmon Ladder.

Despite being barred from competing, Yamada reappeared in SASUKE 31 to cheer on the Black Tigers again. Also, in that tournament, Yamada had a monkey run the course in his place as part of a variety TV show known as Suiyoubi no Downtown. The monkey subsequently timed out on the Soritatsu Kabe, despite taking many shortcuts on the course that would disqualify a normal competitor. Hiroshige also made it to the Second Stage in this tournament however timed out on the Backstream.

Yamada appeared once again in SASUKE 32 to cheer on the Black Tigers, although this time none of his protégés cleared the First Stage for the first time since their debut in SASUKE 29. Also, in that tournament, Yamada was entrusted with the production of promotional content, including 360-Degree Video Walkthroughs of the course. According to the Japanese Wikipedia page for Yamada, he concludes these videos by expressing a desire to return to competing on the course, although this is likely impossible due to his ban.

He was, however allowed to take part in a side event for Suiyoubi no Downtown (like the previous year) where competitors attempt four First Stage obstacles from SASUKE 32 for real, while they attempt another four on a Super Mario Bros. game with the paths in each game designed like their respective obstacle, all within a three minute time limit. He attempted it with 7 other competitors, including Akiyama Kazuhiko and failed at the transition from the Quad Steps to the Rolling Hill

Yamada was allowed to compete in SASUKE 33 for the 20th anniversary of SASUKE. He managed to navigate his way past the Quad Steps and the Rolling Hill, but was unable to complete the TIE Fighter. Producing his worst performance in SASUKE history, failing on just the third obstacle. Here, he was given his lowest starting number, 33 which correspond with the 33rd tournament for SASUKE.

Yamada once again appeared on Suiyoubi no Downtown as part of another SASUKE segment where challengers buy home center supplies and use them to help them through the SASUKE course. Yamada purchased three Styrofoam sheets (each worth 1980 yen/US$17.90) and two brooms (each worth 248 yen/US$2.24) in order to create a boat across the Double Pendulum (essentially skipping it) and a 7m ladder (worth 22,800 yen/US$206.34) in order to skip the Soritatsu Kabe. However, these tactics were in vain, as Yamada fell almost immediately on the TIE Fighter.

Between SASUKE 34 and 37 Yamada continues being the leader of the Black Tigers. In fact, in SASUKE 37 the Black Tigers did their best tournament due to the performances of Yamamoto Yoshiyuki and Isa Yoshinori who both set the mark on making it the furthest out of that group in SASUKE, failing the Cliffhanger Dimension (stationary). Yoshiyuki was the only one who made the first transition, but came short on the second.

Since KUNOICHI 9, he is entrusted as an analyst for the runs of the competitors.
