What is Kenta Iwamoto Foot Sweep System?
The Kenta Iwamoto Foot Sweep System connects standing grips and changes of balance to small inside and outside leg attacks, then develops related clinch combinations.
Standing practice becomes easier to review when a foot sweep is treated as a timing problem rather than a kick at an available ankle. Watch how the opponent steps, where the weight moves, and whether your upper-body connection supports the intended direction. Controlled partner movement is useful before full takedown rounds.
Samurai Foot Sweeps & Leg Trips by Kenta Iwamoto is the matched instructional. Iwamoto covers kouchi and kosoto mechanics, grip fighting, and over-under combinations including sasae and uchi mata. The drills, sequence, and assessment criteria below are an original BJJGraph study plan; use them to organize practice alongside the course and feedback from a coach.

Core Principles
- Observe the step and weight change before attempting the sweep.
- Use upper-body connection to support the intended direction.
- Keep your own stance available after an unsuccessful entry.
- Distinguish an inside target from an outside target.
- Agree on controlled falling and reset conditions before increasing speed.
Key Components
Step observation (Connect an attack to a visible timing cue.) With a partner walking at a cooperative pace, call the target step before attempting a light sweep entry without completing the fall.
Upper-body connection (Relate the hand connection to the lower-body opportunity.) Choose one tie and test whether you can influence the partner’s step without pulling yourself out of balance.
Inside-or-outside choice (Build a two-option decision from actual movement.) Alternate the partner’s stance and select one reviewed inside or outside leg attack, stopping if the target is no longer available.
Controlled continuation (Keep combinations connected to changing balance.) After an unsuccessful entry, return to balanced contact or a coach-approved second attack rather than forcing the first one.
Implementation Sequence
- Step observation: BJJGraph study task: With a partner walking at a cooperative pace, call the target step before attempting a light sweep entry without completing the fall. Key points:
- Connect an attack to a visible timing cue.
- Upper-body connection: BJJGraph study task: Choose one tie and test whether you can influence the partner’s step without pulling yourself out of balance. Key points:
- Relate the hand connection to the lower-body opportunity.
- Inside-or-outside choice: BJJGraph study task: Alternate the partner’s stance and select one reviewed inside or outside leg attack, stopping if the target is no longer available. Key points:
- Build a two-option decision from actual movement.
- Controlled continuation: BJJGraph study task: After an unsuccessful entry, return to balanced contact or a coach-approved second attack rather than forcing the first one. Key points:
- Keep combinations connected to changing balance.
- Connect and review: Link the first two practiced tasks in a constrained round, then add the next stage only when both partners can identify the cue and stopping condition. Record the earliest control failure and return to that stage for the next set.
Where to begin in the instructional
Begin with small inside and outside attacks and their situations, then grip fighting; add over-under combinations after the first timing drills.

Take one idea into your next session
BJJGraph practice suggestion: With a partner walking at a cooperative pace, call the target step before attempting a light sweep entry without completing the fall. Then connect it to upper-body connection. Compare the first lost control point after each round.
