In Judo, Tokui Waza means "favorite" or "best" technique. It's the throw that fits naturally to your body type, and you have practiced it thousands of times to make it an instinctual response. Everyone at the club or local tournament knows that you'll use it, but there's nothing they can do to stop it...you're just that good at it.
The first thing that a beginner should be aware of is that your tokuiwaza isn’t the holy grail it isn’t some technique that will suddenly unlock for you the world of Judo. Indeed your tokuiwaza needn’t be one single technique, for Me my tokuiwaza are:
Uchi Mata - inner thigh throw, this is considered a Major throw in the Gokyo. Its one of Judo's highest point scoring throws. I think its only appropriate to share a video of one of the greatest exponents of Uchimata in my lifetime; Kosei Inoue, demonstrating the technique, which was also one of his favourites.
Ippon Seio Nage - One arm shoulder throw, again one of the greats Toshihiko Koga shows how it should be done. Toshihiko Koga is one of the most innovative and exciting fighters the world has ever seen. Koga truely embraced Judo he took the throws taught to him and developed and amazing range of throws that have since become accepted as part of modern judo. Think of one handed Seoi-nage and somersaulting Sode-tsuri-komi-goshi and you think of Koga.
Ko Uchi Gaki - Minor Inner Hook, this time I've found a video of one of the greatest Judoka that's ever lived. Yasuhiro Yamashita is Japan’s most successful competitor, with an unbroken record of 203 wins. Thats 203 competitive fights and zero losses!!
Kaiten Okuri Eri Jimi - Rolling Sliding Collar Strangle, The demonstrations of this by Koji Komuro are excellent Komuro has fought all over the world recognised as a Japanese Judo Newaza expert, Brazilian Jiu-Jitsu Black Belt & MMA competitor,
Sankaku - Triangle (Choke, Arm Lock, Pin). Last but not least, if I was to talk Newaza, and the greatest ever, I dont think there would be much argument against Katsuhiko Kashiwazaki. Kashiwazaki's variants on tomeonage and transitions to ground are inspiring, In the video link he demonstrates a Sankaku Garami, Jimi and Gatami.
