In the world of judo, few techniques polarize athletes as much as Tomoe Nage and its sideward variation, Yoko Tomoe Nage. Some judoka—like Olympic champion Natsumi Tsunoda—have built entire careers around its devastating efficiency. Others view it as a high-risk gamble, a move that can backfire spectacularly if executed poorly. The technique’s dual nature reflects a broader truth in judo: the most effective weapons are often the most controversial.

To understand why athletes either love or hate Tomoe Nage, we must dissect its mechanics, its competitive edge, and the athletes who have mastered—or been undone by—its nuances. From Tsunoda’s straight-back variation to Haruka Kaju’s tactical versatility, this technique embodies both the art and the peril of modern judo.

What Is Tomoe Nage?

Tomoe Nage (circular throw) is a sacrifice technique (sutemi-waza) where the thrower (tori) intentionally breaks their own balance by falling backward, using their momentum to hurl the opponent (uke) over their head or side. The Yoko Tomoe Nage variation involves a sideways rotation, making it harder for uke to counter or stuff the throw.

According to the Kodokan’s official glossary, Tomoe Nage is classified under Ma-sutemi-waza (rear sacrifice techniques). Its defining feature is the submarine motion: tori places their right foot against uke’s abdominal region while extending their leg and pulling with their arms to create a circular arc. The Yoko prefix simply indicates the direction of the fall—not where uke lands.

Why Athletes Love Tomoe Nage: The Technique’s Irresistible Appeal

For athletes like Tsunoda, Tomoe Nage is more than a throw—it’s a signature. Here’s why elite judoka adore it:

• High reward, low risk (when executed perfectly). A well-timed Tomoe Nage can score an ippon (full point) in one fluid motion, bypassing the need for prolonged grappling.
• Psychological dominance. The technique’s circular motion can disorient uke, making it harder to counter. Tsunoda’s straight-back variation, analyzed by Shintaro Higashi, is particularly effective because it “stuffs” uke’s ability to react.
• Versatility. Tomoe Nage works from standing or off the ground, making it adaptable to different match scenarios. Haruka Kaju, the 2025 World Champion, has used it sparingly but effectively alongside techniques like osaekomi-waza (pinning) and kuchi-gari.
• Elegance. The technique’s fluidity aligns with judo’s aesthetic values. Tsunoda’s Tomoe Nage is often described as “beautiful judo”—a blend of power and precision.

Yet, its appeal isn’t universal. Many judoka, especially those who prioritize newaza (groundwork), view it as a last resort—a move that exposes tori to counters if misjudged.

Why Athletes Hate Tomoe Nage: The Technique’s Fatal Flaws

Tomoe Nage’s risks are as legendary as its rewards. Here’s why many judoka dread it:

• High injury potential. The sacrifice motion can lead to tori landing hard on their back or neck, risking injury. Even Tsunoda has acknowledged that her straight-back variation is “risky” and requires perfect timing.
• Effortless to counter. If uke reads the setup early, they can stuff the throw by breaking tori’s posture or using a kuzushi (balance-breaking) counter like uchi-mata.
• Over-reliance. Athletes like Kaju have shown that Tomoe Nage can develop into a crutch if overused. Without a diverse arsenal, judoka risk predictability.
• Rulebook nuances. The return of yuko (half-point) in 2025 has made scoring easier, but Tomoe Nage still demands precision. A missed throw can result in a shido (warning) for excessive sacrifice.

Natsumi Tsunoda: The Athlete Who Made Tomoe Nage Her Empire

No judoka embodies Tomoe Nage’s duality better than Tsunoda. From her Olympic gold in Paris 2024 to her retirement announcement in early 2026, she redefined the technique’s role in modern judo.

Tsunoda’s straight-back variation—analyzed in a 2026 IJF feature—is rare because it’s highly technical. Unlike the more common Yoko Tomoe Nage, her version requires uke to commit fully to the throw, leaving little room for counters. In her words:

“I don’t want to just throw my opponent. I want to produce them throw themselves.”

Her dominance wasn’t just about the throw—it was about psychology. Opponents knew that resisting her Tomoe Nage often led to a waza-ari (half-point) or worse. By 2025, she had won three World Championships and an Olympic title using it as her primary weapon.

Yet, even Tsunoda’s success didn’t eliminate the technique’s controversies. Critics argued that her over-reliance on Tomoe Nage made her vulnerable to judoka who specialized in newaza or kuzushi-based counters.

Haruka Kaju: The Athlete Who Proves Tomoe Nage Isn’t Everything

While Tsunoda’s career was built on Tomoe Nage, Haruka Kaju’s rise proves that the technique’s value lies in context. Kaju, the 2024 Tokyo Grand Slam winner and 2025 World Champion, uses Tomoe Nage selectively—as one tool among many.

According to JudoInside’s analysis, Kaju’s arsenal includes:

• Drop kata-guruma (shoulder wheel)
• Seoi-otoshi (shoulder drop)
• Kouchi-gari (inner reap)
• Kosoto-gari (major outer reap)
• Newaza (groundwork), including her signature Kaju Roll

Kaju’s approach underscores a key lesson: Tomoe Nage is most effective when used strategically, not as a crutch. Her undefeated record (as of May 2026) stems from her ability to adapt—using Tomoe Nage when it’s the highest-percentage move, but never ignoring other options.

Why Does Tomoe Nage Work? The Physics of a Perfect Throw

Tomoe Nage’s power comes from three biomechanical principles:

1. Momentum transfer. By falling backward, tori converts their body weight into rotational force, propelling uke upward.
2. Leverage. The extended leg acts as a fulcrum, while the arms pull uke’s center of gravity off-balance.
3. Timing. The throw must be executed at the exact moment uke’s balance is most compromised.

Shintaro Higashi’s breakdown of Tsunoda’s technique highlights that her success hinges on uke’s commitment to the throw. If uke hesitates, the technique fails. This is why many judoka prefer Yoko Tomoe Nage—its sideways motion makes it harder for uke to anticipate the direction of the throw.

How to Train Tomoe Nage Without Getting Hurt

Given its risks, how can judoka train Tomoe Nage effectively? Experts recommend:

• Start on a mat. Always practice on a thick, padded surface to minimize injury.
• Leverage a partner with experience. A judoka who understands the technique’s nuances can help refine timing and avoid dangerous mistakes.
• Focus on kuzushi first. Mastering balance-breaking is critical—without it, the throw becomes predictable.
• Film your throws. Reviewing footage helps identify flaws in posture or timing.
• Combine with newaza. Athletes like Kaju show that Tomoe Nage works best as part of a diverse toolkit.
