TraditionalTranslation: standard inside ankle trip
The Standard Inside Ankle Trip executes the fundamental inside ankle hook-and-trip where the attacker, from a clinch position, steps between the opponent's legs, hooks the near ankle with the instep, and pulls it forward while simultaneously pushing the opponent's upper body backward. [1] The hook-and-push creates a lever system: the ankle is pulled forward (fulcrum) while the shoulders are driven backward (force), causing a rotational fall. [1],[2] The technique requires the attacker to time the hook with a moment when the opponent's weight is on the targeted foot. [2] The standard inside ankle trip is one of the most reliable close-range takedowns. [2],[3]
The standard inside ankle trip is the fundamental version of ko uchi gari, taught in judo and wrestling. [1]

You'll know the trip is effective once your partner takes a step back and gets their weight onto that back foot, which creates the opportunity to successfully pick the foot up.
Initiate the inside trip and get your partner to take a step back; once their weight is on the back foot, you'll have a lot of success with the technique.

The standard setup chain: Establish Grip → Off-Balance (Kuzushi) → Execute the Reap/Sweep.
Standard counters include: Sprawl — drop hips back and drive weight down to stuff the takedown attempt / Lift the Targeted Leg — raise the foot being attacked to avoid the reap or sweep / Step Over — lift the targeted leg over the sweeping limb to evade / Counter-Throw — use opponent's committed weight shift to execute a counter technique.
Common variants: Standard trip (blocking or sweeping the support leg while driving the up…); Combination trip (chaining an inside trip with an outside trip when the opp…); Counter trip (using the trip as a counter when the opponent attacks); Clinch trip (executing the trip from a tight clinch position).

Top errors to watch for: Hooking with the toe instead of the instep — the instep wraps the ankle more securely / Not stepping deep enough between their feet, so the hook can't reach / Pushing and pulling in the same direction instead of opposite directions / Hooking the ankle when the opponent's weight is on the other foot — they just lift the hooked foot.
The Standard Inside Ankle Trip is also known as Uchigake (Ashikubi), Standard Inner Ankle Hook, Inside Heel Trip, Ko Uchi Gake Takedown.
