Wrestling at the Aichi-Nagoya Asian Games: Nao Kusaka's Fall and Japan's Power Map

On the mat in Aichi, the scoreboard showed 5-2 and the arena seemed to hold its breath. Nao Kusaka, reigning Olympic champion in the 77kg Greco-Roman category, rose slowly, his shoulders sinking. A few hours earlier, he had made the home crowd erupt with a comeback from 4-9 to 11-9 against Zhadrayev of Kazakhstan. In the decisive bout, with the gold medal one step away, Kusaka let Abdevali of Iran take an early lead and could not catch up. The arena witnessed a paradox: the hero of the quarter-final fell in the final, on home soil, before the expectation of thousands of fans. That was the moment the wrestling competition at the Aichi-Nagoya Asian Games revealed its cruelty. An athlete can possess top-level continental technique, produce elite scoring moves, yet a single slow start brings everything down. I have followed international wrestling bouts for years, and what drew my attention in Aichi was the way Kusaka's silver medal was produced: a repeating behavioural pattern, measurable, and entirely fixable. The Aichi-Nagoya Asian Games took place with Japan as host. Wrestling was among the most anticipated events, since Japan has long been regarded as a powerhouse of the discipline. At recent Games, Japanese wrestlers consistently reached medal bouts, in both men's Greco-Roman and women's freestyle. That status creates a particular pressure: when you are both host and powerhouse, a silver medal is no longer treated as an achievement, but read as a failure. The 77kg Greco-Roman category was the focal point. Greco-Roman rules state that wrestlers may attack only with the upper body and arms, and are not allowed to hold or attack below the waist. This restriction makes scoring far harder than in freestyle, where wrestlers can attack the legs. Every point in Greco-Roman must be traded for strength, position, and refined technique. This is why comebacks in this weight class carry far higher technical value. Nao Kusaka entered the tournament as reigning Olympic champion. He is 25, in the most productive phase of his career. Before the event, he publicly said his goal was to prove "true strength" rather than rely on the glow of an Olympic gold. The way he framed it showed a man setting a standard higher than any external expectation. And that standard became the yardstick for judging his performance in Aichi. The quarter-final was where Kusaka showed his technical peak. The opponent was Zhadrayev of Kazakhstan, a seasoned wrestler. The bout opened unfavourably for Kusaka as he fell behind 4-9. Under Greco-Roman rules, a five-point gap in the middle phase usually means the bout is settled. With no ability to attack the legs, no surprise moves from below the waist, the trailing wrestler is forced to find points through upper-body wrestling, which drains energy and invites mistakes. Kusaka did not accept it. He produced two step-outs, pushing his opponent off the mat area, each worth one point. Then he executed two exposures, turning his opponent's back to the mat, each worth two points. Six unanswered points gave Zhadrayev no chance to respond, lifting the score from 4-9 to 10-9, then 11-9 after a bonus point. That six-point burst is proof of Kusaka's ability to finish bouts under pressure. What stands out is that Kusaka's scoring in that period did not come from luck. A step-out demands that the wrestler control the opponent's centre of gravity and direction of movement. An exposure demands seizing the dominant position and rotating the opponent at the right moment. These are skills honed over thousands of hours, and Kusaka executing them in succession against an elite opponent shows his technical foundation remained intact. Another technical detail decided the quarter-final. Zhadrayev challenged via the video-review system after an exposure was scored for Kusaka. Under competition rules, when a wrestler challenges and loses, the opponent is awarded an extra point. Zhadrayev lost the challenge, Kusaka gained a point, and the bout ended immediately at 11-9. The video-review system, designed to guarantee fairness, became the factor that ended the bout. That is a situation worth pondering for sports governance. A mechanism meant to make refereeing decisions transparent, in this specific case, produced a point decisive to the outcome. Had Zhadrayev not challenged, the bout might have unfolded differently. This raises the question of how combat sports balance protecting athletes' right to challenge against preventing the system from intervening too deeply in results. The final was an entirely different story. The opponent was Abdevali of Iran. From the start, Kusaka let his opponent score first. He let Abdevali take a two-point early lead, creating the very situation he had successfully overturned in the quarter-final, but this time he could not repeat it. The bout closed 5-2 in Abdevali's favour. The gold stayed with Iran, while Kusaka took silver on home soil. Looking at the two bouts on the same day, a pattern becomes clear. In both the quarter-final and the final, Kusaka conceded points first. The difference lay in his ability to respond: in the quarter-final he reacted fast and strong enough to come back; in the final the gap was created at a moment when he no longer had enough time, and Abdevali made no mistakes. The same weakness, two opposite outcomes. This leads to a technical hypothesis: Kusaka's problem may lie in the warm-up phase and his level of focus at the start of a bout, not in his conditioning or technique. A wrestler who concedes early points in consecutive bouts often has an issue in warm-up or in the way he enters a bout, not in his capacity for a long fight. If so, it is a problem fixable through changes in bout preparation. One must also consider the accumulation of physical and mental energy. The quarter-final comeback cost Kusaka a significant amount of energy, both physical and emotional. Entering the final on the same day, facing a fresh opponent in a different psychological state, may have made him start slower than usual. This is a lower-confidence hypothesis, but it cannot be ruled out given the dense schedule of a single competition day. After the bout, Kusaka's remarks drew attention. He said briefly that he was "simply weak". That is a self-assessment far harsher than the reality of the bout. A wrestler who had just produced a six-point comeback against an elite opponent cannot be described with the word "weak". But the phrasing reflects the standard he set himself, and it is also a psychological signal worth tracking. In elite sport, how an athlete interprets his own defeat matters as much as the defeat itself. An excessively harsh self-criticism can become fuel for a stronger return, or a prolonged burden. For Kusaka, who just lost his crown on home soil, the risk of spiralling into self-doubt is real. This is a point the Japanese national coaching staff needs to watch closely in the period ahead. While attention poured on Kusaka, another story carried an opposite tone. In the 97kg Greco-Roman category, Yuri Nakazato won gold. Notably, Nakazato walked onto the podium with a limp, suggesting a leg problem. He competed and won while not fully healthy, and later admitted he never thought he could win. The way Nakazato spoke about his victory creates a stark contrast with Kusaka. If Kusaka entered the tournament as reigning Olympic champion and set himself the standard of proving "true strength", Nakazato entered as a low-expectation athlete. That mindset freed him from pressure and let him wrestle more freely. Sometimes, having nothing to lose is the greatest advantage. In the 97kg category, Nakazato also had to contend with Siwach of India, a highly rated opponent. Overcoming such an opponent while carrying a leg injury shows Nakazato's mental depth. But it also raises a question about his physical condition going forward: an unquantified leg injury could affect his availability at upcoming tournaments. In the women's 62kg freestyle category, Ozaki of Japan also won gold. Her opponent was Kim of North Korea. Ozaki's victory, together with Nakazato's gold, let the Japanese wrestling team close the competition day with an impressive record. This matters greatly in shaping how the story of the tournament is told. Looking only at Kusaka's silver, one might think the Japanese team had a disappointing day. But two other golds on the same day substantially diluted the reputational cost of that result. This is the hallmark of deep teams: one individual's defeat does not bring down the whole programme. The overall story still carries a positive tone. Placing this result in the wider picture of Asian wrestling reveals a familiar order. Japan, Iran, and Kazakhstan are the traditional powers of the discipline. Iran with Abdevali, Kazakhstan with Zhadrayev, are both credible gold-medal contenders. India and North Korea emerge as forces capable of surprises in specific weight classes. Below them are developing federations. Japan's depth shows in having contenders in both men's Greco-Roman and women's freestyle. A nation present across different weight classes and disciplines points to a systematic development model rather than reliance on a few outstanding individuals. This is the foundation that lets Japan sustain its powerhouse status across cycles. But the story the media readily accepts, that Kusaka failed and Japan's star fell on home soil, overlooks a simpler reality. The result in Aichi is not a sign of Kusaka's decline. It is the result of a specific behavioural pattern, one that can be identified and corrected. Looking at the data, Kusaka is 25, at the peak of his career. He had just demonstrated the ability to generate six unanswered points against a top opponent, in a sport where scoring is strictly limited by technique. That ability does not vanish after one defeat. What was lost was one specific gold medal, on one specific day. Reading this as failure is harmful because it directs attention to the wrong problem. If the problem is psychological collapse, the solution is long-term mental support. But if the problem is a slow start, a pattern appearing twice in one day, then the solution lies in bout preparation, in how Kusaka enters the opening minutes. Two diagnoses lead to two entirely different remedies. I believe the second is more likely. The evidence lies in the comeback itself. A wrestler with a weak mentality could not overturn a 4-9 deficit in a tense quarter-final. Kusaka's ability to respond under pressure is real. His problem is timing, not nature. The role of the video-review system also deserves a second look. In the quarter-final, a failed challenge directly ended the bout and handed Kusaka a decisive point. Here lies a question of rule design: does awarding a point to the opponent when a wrestler loses a challenge create a perverse incentive? A system created to protect fairness can become a tool that ends a bout in unpredictable ways. From this angle, combat sports can learn from football, where VAR has also stirred controversy over its level of intervention in results. The difference is that in wrestling, each point carries far more weight than a goal in football, because a bout's total score is usually very low. A point from a challenge can account for a fifth of the entire bout's score. This does not mean the video-review system should be abolished. The issue lies in balancing athletes' right to challenge against the continuity of the bout. On-mat referees, as in football, remain those under the greatest pressure and with the least explanation. Fans in the stands often do not understand why a point is awarded or taken away, and that information gap is an unresolved problem. The media narrative around Kusaka has a predictable cycle. A reigning Olympic champion losing on home soil always produces an attractive headline. But that headline rests on a very small sample: two bouts in one day. One cannot judge an athlete's career trajectory on two bouts, however symbolic they may be. By contrast, Nakazato's gold is a ready-made positive story. A low-expectation wrestler, competing injured, overcoming a strong opponent to win. This is the kind of story the media loves, and it has a solid factual basis. That this story runs alongside Kusaka's helps balance the overall picture. From a risk perspective, the biggest threat to Kusaka is not physical but psychological. An athlete who calls himself "weak" after a defeat may enter the next tournament in a different frame of mind. If he lets this disappointment linger, the risk of an early exit at the next event is real. This is a medium-probability but high-impact risk. The second threat is Nakazato's injury. He won gold while limping, and the condition of his leg has not been disclosed in detail. If the injury is more serious than expected, it could affect his presence at upcoming tournaments. A gold medal does not guarantee that a physical problem has been resolved. Overall, the risk assessment of Japan's performance in Aichi sits between low and medium. No financial or governance risk appears in this picture. The main risks are sporting and psychological, tied to two specific individuals: Kusaka with his slow-start pattern, and Nakazato with an unquantified injury. Heading into the next cycle, the question is not whether Kusaka has talent. The question is whether he can fix his weakness in the opening minutes. At 25, he still has a full Olympic cycle ahead. Time is on his side, but time waits for no one. The data from Aichi shows one thing clearly: the gap between Kusaka's gold and silver does not lie in technique. It lies in the opening minutes, in how he enters a bout, in the moment he lets an opponent score first. It is a small gap technically but a large one in terms of results. For the Japanese national team, the competition day in Aichi leaves a two-sided picture. One side is the disappointment of its brightest star. The other is the affirmation of the programme's depth, with golds coming from different weight classes and disciplines. The resonance of these two sides is what is truly notable. What I carry away from the competition day in Aichi is a lesson in reading a behavioural pattern. The majority looks at the star; I look at the gap. Kusaka's gap is not talent. It is the opening minutes of a bout, where everything can be decided before the bout truly begins. Elite sport has no randomness, only data not yet read. Kusaka's case is an example: a silver medal looks like a collapse, but read closely, it is a fixable behavioural pattern. Do not ask who will win, ask who will not collapse, and in Aichi, the one who did not collapse was not the most expected name.
