Denuma Taiki 出沼 大樹

Most sumo fans first heard of Denuma Taiki not because of a bout he won, but because of a fried chicken recipe he created. His signature "Karaage no Numa" (The Fried Chicken Swamp) was featured on national television, turning this quiet Sandanme wrestler into an unlikely culinary celebrity. But there is far more to Denuma than cooking.

At 178 cm and nearly 170 kg, Denuma carries one of the most formidable physiques in the lower divisions. He is a genuine heavyweight in a world where many of his opponents at the Sandanme level are 20 to 40 kg lighter. When he locks onto a target and drives forward, the result looks less like a sumo match and more like a controlled demolition. His thrust-and-push style is built entirely around this advantage — no belt tricks, no finesse, just unyielding forward pressure until his opponent is off the clay.

Denuma fights under his real surname, a choice that reflects a straightforward personality. Born in the industrial port district of Kawasaki-ku, he attended a vocational high school where the sumo club was a minor afterthought until a dedicated coach turned it into a nationally competitive program. When former Ozeki Miyabiyama came scouting in 2018, Denuma was the wrestler he wanted above all others in the country.

Seven years into his professional career, Denuma remains a work in progress. He has tasted Makushita — the final stepping stone before the salaried ranks — but has not yet been able to stay there. His 28-42 record at that level tells the story of a wrestler who can compete with better opponents but cannot yet do so consistently. At 25, the question is whether his raw power can be refined into something more before time runs out.

The Mukaino-oka Story

Kanagawa Prefectural Mukaino-oka Industrial High School (向の岡工業高校) is not the kind of institution that produces professional sumo wrestlers. Located in Kawasaki, it is a vocational school focused on engineering and manufacturing — the kind of place where students learn to weld, not to wrestle. But under the guidance of coach Kiyota Hidehiko, the school's sumo club became something extraordinary.

Kiyota's approach was unconventional. He incorporated bodybuilding methods into sumo training, a cross-disciplinary strategy that produced remarkable physical transformations. Under his program, wrestlers gained an average of 20 kg of mass in a single year — not fat, but functional weight distributed across frames that were being trained to generate explosive force. Denuma, already naturally heavy, thrived in this environment.

National Success

The results came quickly. In 2017, Denuma helped lead Mukaino-oka to 3rd place at the 101st National High School Sumo Kanazawa Tournament — an achievement that was unprecedented for the school and represented its best showing in roughly 40 years. The following year, 2018, the team placed 3rd in the team division at the Inter-High Championships (National High School Athletic Meet), cementing the program's reputation on the national stage.

For a vocational school with no sumo pedigree, competing at this level was remarkable. It caught the attention of professional stables looking for raw talent that could be shaped at the professional level — and one former Ozeki in particular was watching very closely.

Futagoyama Oyakata — the former Ozeki Miyabiyama, himself once one of the most powerful thrust-and-push wrestlers in the top division — saw something special when he visited Mukaino-oka's practice sessions. He later spoke about the encounter in blunt terms:

It was the highest possible endorsement. Miyabiyama had been a two-time Ozeki who reached the rank through sheer pushing power, and he recognized something of himself in the heavy-set teenager from Kawasaki. Denuma was the second graduate from Mukaino-oka Industrial to join Futagoyama Stable, following Tainaka Ryusho, suggesting a pipeline between the school and the stable built on trust between coach and stablemaster.

For his part, Denuma was ready for the challenge. When he announced his decision to turn professional, he said simply:

There was, however, reportedly one additional factor that sealed the deal — the promise of all-you-can-eat sweets at the stable. For a teenager about to enter the grueling world of professional sumo, the appeal of unlimited desserts should not be underestimated.

Thrust-and-Push: Destructive Power

Denuma is a textbook tsuki-oshi (thrust-and-push) wrestler. He does not reach for the belt. He does not attempt throws. He puts his hands on his opponent's chest and drives forward until there is nowhere left to go. At 169.6 kg, the physics are simple: when he gets moving, stopping him requires extraordinary strength or exceptional footwork.

His technique breakdown tells a clear story:

Oshidashi (push out) accounts for over a third of his wins. This is the signature technique — sustained, heavy pushing that forces the opponent backward across the tawara. Tsukitaoshi (thrust down) at 16% shows his ability to knock opponents off balance with powerful arm thrusts. Okuridashi (rear push out) at 11% reflects his skill at getting behind opponents who try to sidestep his charge and finishing them from behind.

The weakness in this approach is clear: when opponents can absorb his initial charge and force a longer bout, Denuma's stamina becomes a factor. His massive frame is built for explosive power, not endurance. Skilled technicians who can redirect his momentum or pull him off balance are his most dangerous opponents — a pattern reflected in his 28-42 Makushita record, where such opponents are far more common.

Denuma's career splits neatly into two stories depending on which division he is competing in.

This gap defines Denuma's career challenge. In Sandanme, his physical advantages are often decisive. He is bigger, stronger, and heavier than most of his opponents, and his straightforward pushing style works because opponents lack the technical refinement to counter it. He dominates through sheer physical superiority.

But Makushita is where sumo gets serious. The wrestlers at this level are either on their way up with genuine sekitori potential, or experienced veterans who have been competing at this level for years. They know how to handle a big man charging forward. They step aside. They pull. They get to the belt and neutralize the weight advantage. Denuma's one-dimensional approach, so effective below, becomes a liability.

The question for Denuma and his stablemaster is whether he can add a second gear — some belt work, better lateral movement, improved ring awareness — without sacrificing the raw forward power that is his greatest asset. At 25, there is still time. But the window is not infinite. Most wrestlers who are going to break through to Juryo do so by their late twenties.

Karaage no Numa (The Fried Chicken Swamp)

In the hierarchical world of sumo, lower-ranked wrestlers are responsible for cooking the stable's communal meals. Denuma embraced this duty with unusual enthusiasm. As chanko-ban (meal preparer) at Futagoyama Stable, he developed a repertoire of dishes — but one creation in particular catapulted him to a kind of fame that most Sandanme wrestlers never experience.

His signature recipe, "Karaage no Numa" — roughly translatable as "The Fried Chicken Swamp" — was featured on Fuji TV's popular variety show "Uwasa no Okyaku-sama." The segment went viral, introducing Denuma to an audience that had never watched a sumo bout in their lives. For a wrestler ranked in the third-lowest division, it was a surreal experience: recognized on the street not for his sumo, but for his chicken.

The All-You-Can-Eat Sweets Decision

Denuma's relationship with food extends beyond cooking. When he was deciding which stable to join as a fresh high school graduate, one factor reportedly tipped the scales: the promise of all-you-can-eat sweets at Futagoyama Stable. While the stablemaster's endorsement and the stable's training philosophy were certainly the primary draws, the unlimited dessert policy did not hurt. For a young man who would eventually weigh nearly 170 kg, the priorities were perhaps already clear.

The March 2026 basho has been a welcome recovery for Denuma. After his worst-ever result of 1-6 in January at Sandanme 10, many wondered whether the 25-year-old had the mental resilience to bounce back. His 4-2 record through Day 14 at West Sandanme 48 suggests that he does.

A winning record this tournament would halt his slide and set up a return to the upper reaches of Sandanme in May. From there, the path back to Makushita is well-traveled ground for Denuma — he has made the journey before. The harder question is what happens if he gets there again. His 28-42 Makushita record shows that raw power alone is not enough at that level.

At 25, Denuma is approaching a crossroads. He has the physical tools — 170 kg of forward-driving mass is a weapon that never goes away. What he needs is tactical evolution: better defensive positioning, some basic belt technique for when pushing fails, and the conditioning to sustain his power for a full seven-bout tournament at Makushita intensity. Under the tutelage of a former Ozeki who mastered exactly this kind of evolution during his own career, Denuma has the right teacher. The question is whether the student can learn the lesson in time.
