Nage Waza - Sumi Gaeshi

Sumi Gaeshi

Sumi Gaeshi, also known as the corner throw, is the first technique in the Dai Yonkyo from the Gokyo no Waza.  To execute Sumi Gaeshi:

1. Break uke's balance to his/her right front corner.
2. Fall back, placing your right foot instep in the crook of uke's left knee or on his/her left thigh.
3. Raise your leg while falling (not after you touch the mat) and throw uke over your head.

Here's a montage of sumi gaeshi from competition to give you some idea of how it's used:

Grip fighting techniques

Shoulder rolls

• Practice rolling your shoulder away from a grip
• Practice rolling your shoulder into and through a grip

Break his sleeve grip (starting from he has your sleeve and you have his)

• Reach over your other arm
• Drive his hand into your other hand (really stretch him out and turn your body into it)
• Immediately come back to your stance (like your elbowing him in the face with the arm you just freed)
• If you go to slow and he starts to reach over you for a back grip, hook his leg and drive for o soto gari
• Immediately go for a high shoulder or back grip with your newly freed hand

So I've been away for a while working on other things, like a new job (which is now my old job) and a masters degree, but I'm back now, and I've advanced to Sankyu, which means I'm sometimes responsible for running classes. Here's what I've got planned for my next class:  

Overview

Review

Discuss:

• What did we do last week?  What did you learn?
• What are the 8 throws of Dai Ikkyo?
• What are the 5 common osaekomi?

Skills

Dai Ikkyo
Execute each throw 5 times with a partner, alternating so your partner gets to throw.  If you know them, make the quick, crisp, and clean.  If you don't, just go with the flow and make them quick.

Breaking Grips
This YouTube video from Matthew D'Aquino, an Australian judoka who competed in the 2008 Olympic games, describes how to break the standard collar grip and the top grip:



Practice breaking the standard collar grip 10 times with a partner, alternating so your partner gets to practice.  Have your partner gradually increase his/her resistance.  Keep in mind the following:

• Grab uke's sleeve, pulling down to make it tight on uke's wrist
• Bend your knees while maintaining good posture
• Put your other hand on top of uke's wrist
• Stand up and push uke's hand toward his/her belt
• Don't let go - get your own grip and move into position for a throw

Think sleeve-knees-top-belt, then throw.

Practice breaking the top grip 10 times with a partner, alternating so your partner gets to practice.  Have your partner gradually increase his/her resistance.  Keep in mind the following:

• Keep your posture
• Grip uke's sleeve at the elbow
• Put your chin on uke's wrist and break his/her posture (torque his/her body)
• Quickly put both hands on uke's sleeve and break

Think elbow-chin-torque-break.

3. Execute nage komi 10 times with a partner, alternating so your partner gets to fit as well.

1. Execute moving uchi komi 10 times with a partner, moving forward and back, alternating so your partner gets to fit as well.
2. Execute nage komi 10 times with a partner, alternating so your partner gets to throw as well. 
3. Execute sute geiko 5 times with a partner, having your partner try to dance away from your attempted throws (light or no upper body resistance).  Alternate so your partner gets to throws as well.
