Groundwork, hardening technique skills. In Osaekomi the opponent is lying literally on there back side, these techniques are used to immobilize your opponent, or make them unable to move.
Typical groundwork is to get the opponent on there back and keep them from moving for 20-seconds to win by ippon. In the GIF to the left you can see the judoka from Mongolia turn her opponent over into a very solid upper body hold-down.
"Osae komi waza" (Hold-down techniques) is one of Katame-waza (grappling techniques) (Ne waza [Ground techniques]), and consists of covering the opponent with your body, etc., to prevent him from escaping.
There are Five basic Kodokan judo "Hold-down Techniques" to learn, these five will give you a strong foundation to build your ne-waza [Mat Techniques or Ground Fighting skills].
(KAIZEN-IMPROVEMENT) "KAIZEN SHOULD BE NEVER ENDING"
Here are some competition examples of Ne-Waza/Ground Fighting
Katame-waza (grappling techniques) consist of three categories:
- Kansetsu-waza [Joint Locks]
- Osae-Komi-Waza [Hold-down Techniques]
- Shime-Waza [Strangling Techniques].
Ude-gatame [Arm Lock]
[KANSETSU-WAZA]: JOINT TECHNIQUES (LOCKS)
Kesa-gatame [Scarf or Collar Hold-down]
[Osae-Komi-Waza]: Holding or pinning techniques
Okuri-eri-jime [Sliding Collar Choke]
[Shime-waza]: Strangulation techniques
Below are the three categories of mat techniques of Katame-waza. At the beginning we will be focusing on Osae-Komi-Waza (Hold Down Techniques). For ease of learning we will be applying these techniques via drills for now.

CURRICULUM: Osae-Komi Waza [Hold-downs]
(1) Kesa-gatame (Scarf hold)
This basic Osae komi waza (Hold-down techniques) favors heavyweight division combatants.
Features of this Waza
In the Kesa-gatame (Scarf hold) Waza, Tori (Player executing technique) wraps an arm around Uke (Player receiving opponent's attack) neck and pins Uke (Player receiving opponent's attack) with his upper body.
Tori (Player executing technique) wraps an arm around the back of Uke (Player receiving opponent's attack) neck, and pins his upper body as if hugging him.
At this time, one of Uke (Player receiving opponent's attack) arms (on Tori (Player executing technique) chest side) is scissored and locked against Tori (Player executing technique) side, disabling it.
Tori (Player executing technique) then brings his face close to Uke (Player receiving opponent's attack) face to firmly pin Uke (Player receiving opponent's attack) with his upper body.
In order to maintain balance as Uke (Player receiving opponent's attack) attempts to move, Tori (Player executing technique) extends one leg forward, and rests his other leg on his flexed knee.
The pinned Uke (Player receiving opponent's attack) may try to pull on Tori (Player executing technique) back from below in order to turn him over, but Tori (Player executing technique) can repel this by releasing his hold on Uke (Player receiving opponent's attack) neck and placing that hand against the floor for balance and support.
In actual competition, combatants may escape this hold-down by twisting at the waist and raising their hips, though this escape maneuver favors women combatants with flexible bodies.
The "Kesa-gatame" (Scarf hold) name comes from the fact that it resembles the over-one-shoulder robe worn by priests.
This is a fundamental Waza in Judo, and one of the first that beginners learn.
