Jiyu ippon kumite 自由一本組手
Semi-free one-step sparring
In plain words
One announced attack, but from free-fighting guard and distance, with both partners moving. The bridge between prearranged practice and free fighting, and the exercise where most of what actually works in kumite is learned.
Purpose. To join the technical answer to the distance problem. The defender must control maai while the attacker is actively trying to break it — which is the whole of free fighting, with only the choice of attack removed.
Where it leads. Leads directly to jiyu kumite, and everything in it transfers.
How the exercise runs.
- Both partners take free-fighting kamae and move.
- The attacker announces the attack and level, then chooses their own moment to close and attack.
- The defender manages distance while the attacker sets up, then blocks or evades and counters.
- Reset to fighting distance; repeat.
Partner work injures people when it is done carelessly.
- Control is absolute. Both partners are moving and the distance is closing under someone’s initiative, which is when accidents happen.
- Agree the level and stick to it.
- Stop on the instructor’s call, immediately and every time.
Common errors, and how to fix them.
Why it happens. Retreat is the instinct and it works for a while.
The fix. Angular movement and counter-attacking on the attacker’s preparation. Drill with a marked area so running out is immediate.
Why it happens. Gathering for the effort.
The fix. Attack from movement, not from a pause.
Why it happens. Waiting to be safe.
The fix. Counter on the attacker’s recovery, not after it.
Drills
- Announced jodan attack only, defender free to answer however they choose.
- Defender forbidden to move straight backward for the whole round.
- Defender must counter before the attacker’s attacking hand returns to guard.
The Japanese, explained.
- Jiyu ippon kumite 自由一本組手
- Semi-free one-step sparring. One announced attack, from free-fighting distance and guard, with both partners moving. The bridge between prearranged practice and free fighting.
- Kamae 構え
- Guard, posture of readiness. The position taken up facing an opponent — feet, hips, hands and eyes together. A good kamae threatens without committing, and gives away nothing about what is coming.
- Maai 間合い
- Engagement distance. The distance between two people, understood as a relationship rather than a measurement: the same gap is close for a tall fighter and long for a short one, and it changes the instant either moves. Controlling it is the largest single skill in free fighting.
- Tai-sabaki 体捌き
- Body management. Moving the body off the line of an attack while staying close enough to answer it.
