Masakuzu Imanari Breaks Down Polaris 4: Strategies, Heel Hooks, and Championship Predictions

Diving into Polaris 4 with Masakazu Imanari

Masakazu Imanari, the iconic Japanese grappler famous for his lightning-fast leg attacks and the "Imanari Roll," is gearing up for Polaris 4. This high-stakes no-gi invitational tournament brings together the world's top submission wrestlers in a format reminiscent of ADCC, with matches focused purely on grappling excellence. For fighters and fans alike, Imanari's perspective offers a goldmine of insights into preparing for such elite competition, whether you're rolling in BJJ, training for MMA, or honing your wrestling base.

Imanari has long been a pioneer in leg locking, especially heel hooks, which he popularized in the gi and no-gi scenes. Competing at Polaris 4, he'll face off against some of the best, testing his adaptability in a ruleset that emphasizes submissions over points. Let's break down his thoughts on the event, his approach, and what it means for combat sports enthusiasts looking to level up their game.

Imanari's Prep and Mindset for the Big Stage

When preparing for Polaris 4, Imanari emphasizes a balanced training regimen that mixes drilling, live rolling, and recovery. He stresses the importance of studying opponents' footage—something every serious grappler should do. "Knowing their strengths and weaknesses is key," he notes. For MMA fighters transitioning to no-gi grappling or wrestlers adding submissions, this scouting process translates directly: analyze patterns in takedowns, guards, and escapes.

His daily routine includes:

  • Specific drilling: 100+ reps of heel hook entries from various positions, like the Imanari Roll from turtle or single-leg X.

  • Positional sparring: Starting from disadvantageous spots to build resilience.

  • Strength and conditioning: Focus on explosive hips and grip strength, crucial for leg entanglements.


Practical tip for enthusiasts: Incorporate Imanari's roll into your warm-ups. Start on your knees, explode into the back-take position, and chain it into an ashi garami (leg entanglement). This builds the athleticism needed for modern no-gi battles, applicable in BJJ tournaments, MMA ground games, or even kickboxing clinch work.

Breaking Down Key Matchups

Polaris 4 features stacked brackets, and Imanari has strong opinions on the outcomes:

  • Featherweight division: He predicts a tight battle but favors certain athletes based on their guard passing and submission chains. For example, he highlights how one competitor's kneebar defense could be a game-changer.

  • Middleweight showdowns: Expect heavy action with wrestlers dominating early, but Imanari sees leg lockers prevailing late.

  • His own path: Facing a mix of styles, he'll rely on his trademark entries from the bottom, turning defense into offense.


These predictions aren't just guesses—they stem from years of competing against similar foes. In MMA contexts, understanding these dynamics helps strikers defend takedowns and grapplers chain attacks seamlessly.

Mastering the Heel Hook: Imanari's Signature Weapon

No discussion with Imanari is complete without diving into heel hooks. He details his favorite setups:
1. Imanari Roll: From turtle position, roll backward to expose the heel while securing the far leg. Control the hips to prevent stacks.
2. Single-leg entries: Attack from failed takedown attempts, transitioning to inside sankaku or 50/50.
3. Outside passes: Use speed to pass to the side and isolate the leg before the opponent reacts.

He warns about common mistakes: rushing the finish without control leads to escapes. Instead, methodically stack and rotate for the tap. For beginners in BJJ or wrestling, start slow with body triangles to simulate pressure without full risk.

In Muay Thai or kickboxing gyms, these techniques enhance clinch breaks and sprawl recoveries. Gear-wise, Imanari recommends high-quality rash guards and shorts like those from Scramble for optimal mobility—no bunching fabric during leg locks.

Gear Essentials for No-Gi Grappling

Competing at this level demands reliable equipment. Imanari sticks to trusted brands for rash guards, spats, and shorts that wick moisture and allow full range. Key features:

  • Grip-resistant fabrics: Prevent slips during scrambles.

  • Reinforced seams: Handle intense twisting in leg locks.

  • Compression fit: Supports muscles without restricting blood flow.


For training at home or in the gym, pair with quality grappling dummies for solo heel hook practice. Apollo MMA stocks a range of no-gi apparel from top manufacturers to keep you performing at peak.

Predictions and What to Watch For

Imanari's bold calls:

  • Overall winners: He tips specific names in each weight class, citing their adaptability.

  • Dark horses: Up-and-comers with unorthodox guards could upset veterans.

  • Technique trends: Expect a surge in front headlocks and leg attacks, influencing future MMA ground games.


Watch Polaris 4 live to see these play out—it's a masterclass in no-gi. Post-event analysis will refine your own training.

Applying Polaris Lessons to Your Training

Whether you're a weekend warrior in BJJ, an MMA fighter building ground control, or a wrestler adding subs, Imanari's wisdom is actionable:

  • Drill chains: Heel hook → kneebar → back take.

  • Mental prep: Visualize matches to handle pressure.

  • Recovery focus: Ice legs post-training to stay fresh.


Extend this to boxing or kickboxing by improving hip mobility for better kicks after ground work. Gear up properly—check Apollo MMA's selection of rash guards, shorts, and protective spats to match pro-level quality.

Imanari's journey reminds us: consistency and innovation win titles. Tune into Polaris 4, study the breakdowns, and elevate your game today.
