Yamamoto Shingo (山本 進悟) is a former gas station manager from Tokyo. He is part of the SASUKE All-Stars. He is the only person to have competed in every SASUKE competition, and the only person to have attempted the first and second version of the Final Stage. He usually competed in his gas station uniform shirt and cap (always with Esso/Mobil branding) until SASUKE 28 when he changed careers.

Personal History

Much note is made of Yamamoto's career and personal successes. These include his promotions at the Hasegawa service station, where he started as a gas jockey in the 1st Competition. He became manager before the 6th and was announced as a district manager at the 17th. His personal achievements include his marriage after the 5th competition and the building of his home in Tokyo, complete with a SASUKE training course.

Of the 36 tournaments he has entered, he has passed the First Stage 16 times, the Second Stage 11 times, and the Third Stage twice. He is one of only six competitors who have reached the Final Stage more than once (the others being Omori AkiraNagano MakotoUrushihara Yuuji, Matachi Ryo and Morimoto Yusuke).He has worn high numbers numerous times after SASUKE 3. Yamamoto also competed on VIKING, failing the Swing Mast, the next-to-last obstacle in the first stage after his feet touched the water.


Early tournaments

In SASUKE 1, he blazed through the First Stage clearing it with 29 seconds left, but in the Second Stage he failed the Goren Hammer, losing his balance after clearing the main portion of the obstacle. In SASUKE 2 he made it to the Third Stage, however he struggled on the Pipe Slider and failed here while moving on the final track. In SASUKE 3 he took his revenge on the Pipe Slider and made it to the Final Stage, before timing out 2 meters under the goal. In SASUKE 4 he performed very poorly by failing the Yureru Hashi, trying to touch the axis with both his hands.

Mixed success

In SASUKE 5 he would become the only competitor to reach the Third Stage, clearing the Second Stage with a mere 0.3 seconds left. On the Third Stage unfortunately he failed the final jump on the Pipe Slider, missing the Final Stage by inches. If he had cleared the Third Stage, SASUKE 5 would have been the only tournament with a 100% clear rate of Third Stage. He started SASUKE 6 in a good shape, because he became the gas station manager few days before the competition, however he shockingly failed the Rolling Maruta. In SASUKE 7 he would avenge his past two failures becoming the first competitor to attempt the Final Stage after Akiyama Kazuhiko's kanzenseiha. However, his attempt finished almost immediately due to a dislocated shoulder, an injury that influenced Yamamoto's career. In SASUKE 8, despite the heavy rain, he made it to the end to the First Stage, but unfortunately he tried to rush to the buzzer causing him to fall backwards and being unable to press the button in time. In SASUKE 9 he returned to the Third Stage but he was defeated on the first obstacle, the Rumbling Dice, failing to land to the platform after clearing the main obstacle. In SASUKE 10, he performed well until the Tarzan Rope. There, he struggled and lost a lot of time, causing him to time out on the Rope Climb again.


In SASUKE 11 he would again return to the Third Stage and made it all the way to the Cliffhanger before failing the 2nd transition. In SASUKE 12, he would failed in the same identic fashion. In SASUKE 13 he easily cleared the First Stage but in the Second Stage he struggled in the Chain Reaction and the Balance Tank (clearing it with a terrific jump), causing him to rush on the Wall Lifting, and timing out just before hitting the buzzer, also because to a foot trapped by the third wall. In SASUKE 14 he would take revenge on the Wall Lifting and fail the Curtain Cling in the Third Stage. In SASUKE 15 he would barely clear the First Stage with 3.88 seconds left. In the Second Stage he cleared with the fastest time of 10.1 seconds. In the Third Stage he would fall early on the Body Prop which he had passed in the previous tournament. In SASUKE 16 he performed badly as he nearly fell from the Sandan Rolling Maruta and Cross Bridge, and when he reached the Jump Hang his feet skimmed the water, disqualifying him. In SASUKE 17 he would once again fall on the Body Prop.


During Shin-SASUKE (the era after Nagano Makoto's kanzenseiha), his results were lackluster as he failed the First Stage 5 straight times. In SASUKE 18, he made it far into the First Stage. But while trying to reach the net of the Flying Chute, his hand missed the rope, and he fell into the water. In SASUKE 19, he showed decent speed (getting caught up in the Pole Maze), but landed poorly on the Jumping Spider and fell.

In SASUKE 20, his run was perfect up until the Half-Pipe Attack. He reached the rope, but when landing, he failed to steady himself and fell off the side of the mat. In SASUKE 21, he avenged his defeats of the past two tournaments and made it back to the Flying Chute. He had plenty of time (almost one full minute), but did not have enough momentum to reach the net underneath the Flying Chute. Eventually, his foot grazed the water, and he was eliminated.

In SASUKE 22, his run was, again, perfect up until the Half-Pipe Attack. Like his run in SASUKE 20, he beat the main part of the obstacle, but fell into the water on the plank connecting the Half-Pipe Attack to the Soritatsu Kabe, apparently failing to notice that the path was angled differently from previous tournaments.

Finally, in SASUKE 23, Yamamoto was able to clear the First Stage for the first time in Shin-SASUKE. He added to this success by clearing the Second Stage with little time to spare. However, while attempting the Arm Rings - the Third Stage's first obstacle, Yamamoto re-injured his shoulder, and he gave up on the obstacle to prevent further injury.

In SASUKE 24. He performed well up until the Half-Pipe Attack, an obstacle that has given him all kinds of trouble in the past. Yamamoto made a common mistake of failing to set foot on the Half-Pipe Attack platform and retreating back to the wall, this happened twice until he finally landed on the platform. It took him several attempts to clear the Soritatsu Kabe and he knew he did not have enough time to clear the stage when he reached the Slider Jump. Moving very slowly through the rest of his run, he ultimately timed out before he could attempt the Rope Ladder. This brought Yamamoto's first stage failure count to 11.

Kanzen Renewal

In SASUKE 25, Yamamoto did the best out of the All-Stars in that competition. He had small struggles in the First Stage, but cleared with 6.85 seconds left. In the Second Stage, He failed the redesigned Balance Tank, he tried to jump midway through the track like he had done in previous tournaments. However, he couldn't grab the rope and failed. However, this is his first time Shingo made it the furthest out of the All-Stars since SASUKE 7 and his first time failing the Second Stage since SASUKE 13.

In SASUKE 26, Yamamoto wore #94 and was one of just three All-Stars to attend. During the tournament, he cleared the first two obstacles easily. However, on the Rolling Escargot, he lost his footing and failed there..

In SASUKE 27 Yamamoto wore #81. He took his revenge on the Rolling Escargot and made it all the way to the Spin Bridge where he fell at the last ball.


In SASUKE 28, Yamamoto wore #98. He failed the Spin Bridge for the second time in a row. 

Before SASUKE 29, there was a rumor that the All-Stars would no longer compete, but the rumor was proven to be false, as Yamamoto competed again, wearing #36 alongside his fellow former All-Stars, Nagano Makoto and Takeda Toshihiro. He managed to clear the 1st Stage. However, on the 2nd stage, he was unfamiliar with many obstacles and he fell victim of the reduced time limit. He made it to the middle of the Backstream before retreating and stopping there due to the force of the jets. Ultimately, he timed out. In his post-run interview he stated that he was surprised by the power of the Backstream's current as he is a good swimmer.

In SASUKE 30, Yamamoto cleared Stage 1 despite being digested. In Stage 2, Yamamoto tired himself out on the first four obstacles and for the second straight tournament failed the Backstream when he involuntarily sucked in some water and had to retreat to the side of the pool to catch his breath, ultimately timing out.

In SASUKE 31, Yamamoto tried to jump from the top barrel of the Rolling Hill, but failed.

In SASUKE 32, Yamamoto competed with the number 99 (wore this number for the first time). His run was digested (although his full run was shown on Challenge), but he failed the Double Pendulum when he attempted to transition to the sandbag on his first swing and could not get a grip.

In SASUKE 33, he was once again stopped by the Double Pendulum yet again, as he failed to reached the trapeze bar ending his run.

His streak of failing the Double Pendulum continued in SASUKE 34, as he failed the obstacle for the third consecutive time. This time he got a grip on the trapeze bar, but his right hand missed and he slipped off.

In SASUKE 35,Yamamoto competed with number 74. This time he failed the Fish Bone as he fell on the last step.

In SASUKE 36, Yamamoto competed with number 81. This time he failed the Wing Slider when his foot slipped.

In SASUKE 37, Yamamoto wore #84 and he avenged his past two defeats by completing the Wing Slider and the Fish Bone. However he did not jump far enough on the Dragon Glider and missed the first bar with his right hand, resulting in failure.


Yamamoto made an appearance in the 2nd VIKING competition. Unfortunately, he failed the First Marine Stage on the Swing Mast obstacle.


In January of 2010, Yamamoto along with fellow SASUKE All-Stars Nagano Makoto and Takeda Toshihiro, made his debut in Pro Sportsman No. 1 with the 2010 Monster Box competition. He cleared up to the 13th level, failing on the 14th level at 2 meters, 16 centimeters.
