IMANARI ROLL

The Imanari roll is the standing-to-leg-entanglement entry developed and popularized by Japanese MMA grappler Masakazu Imanari in the early 2000s. The technique converts a standing exchange into a leg-lock position in a single rolling motion — the attacker drops to the floor, rolls under the opponent's legs, and emerges with one of the opponent's legs captured in a saddle or single-leg-X configuration suitable for the inside heel hook finish.

The mechanics begin from a standing exchange where the attacker has identified the opponent's lead leg as the attack target. The attacker drops to the floor on their side, plants one shoulder, and rolls under the opponent's body, simultaneously hooking the lead leg with one of their own legs. As the roll completes, the attacker emerges with the captured leg locked in the figure-four configuration of the saddle (or, alternatively, single-leg-X), with immediate access to the inside heel hook.

The Imanari roll is one of the most dramatic standing-entry techniques in modern grappling and one of the few that produces direct leg-lock access from a no-grip standing exchange. The cost is exposure during the rolling moment — the attacker is briefly underneath the opponent and committed to a specific direction, which an alert opponent can punish with a back-take. For this reason the technique is most effective against opponents who are themselves committed to a wrestling-style standing exchange and have not yet recognized the leg-lock threat. Masakazu Imanari used it extensively in early-2000s MMA; Garry Tonon, Craig Jones, and the modern no-gi competitive roster have continued the tradition.
