how did the arm lock the Kimura in Brazilion JuJitsu get it's name?

Helio Gracie fought a Japanese fighter named Kimura and he broke Helio's arm with an arm lock therefore its been called a kimura.

I am sure everyone who is watching IPL must be getting these negative thoughts heavily spoiling the taste of enjoying the roller-coaster cricket called T-20. This is a good example of how dearly we pay for corruption.... it spoils the entire show for everyone even remotely connected and not actually involved in the act or abetting it. The society pays for every bit of corruption. This is what really proves the immense intrinsic value of 'justice' and 'truth'. If corruption in sports can give us such jitters and misgivings, just imagine what we are in for due to corruption in key areas like education, social service, charity, politics, health services etc.!! And let's not beat around the bush...... it's not just the third world countries or developing nations like India or China alone..... the malaise is widespread covering almost all nations and the entire humanity..... more importantly, it is not only driven by economics, but also all other aspects of human aspirations and aims.

It's named after Judoka, Masahiko Kimura. In Judo it's known as the Ude-garami. Kimura used this move to beat Helio Gracie.

The Answer is....

You're a self-absorbed Jerk covering up his feelings of grappling inadequacy because he's upset that BJJ is more popular by asking "educational" questions.

Get over yourself and go watch the video of BJ Penn winning a Judo tournament that he didn't even have to read the rules for.

because from the pictures, when you apply it it looks like a "K" with your arms...and kimura starts with a "K".

Taken from "My Judo" by Masahiko Kimura

One day, Helio Gracie, judo 6th dan, issued a challenge to us. The rule of the bout was different from that of judo or pro wrestling. The winner was decided by submission only. No matter how cleanly a throw is executed or how long Osaekomi lasts, it does not count. He issued a challenge to Kato 5th dan first. The gong rang. Kato was in good condition, and threw Helio a number of times. However, past 15 minute mark, I started to see frustration in Kato's face. The throws had no damage on Helio since the mat was soft. At 30 min mark, it was evident that Kato was tired. "What's the matter, Kato, go to Newaza, don't stand up!" Japanese audience yelled. Kato then threw Helio down by O-soto-gari, mounted on Helio, and started Juji-jime. The audience roared with excitement. But, as I watched carefully, Helio was also applying a choke from below. They were trying to choke out each other. This lasted about 3 or 4 minutes. Kato's face started to turn pale. I shouted, "Stop!" to the referee, and jumped into the ring. When Helio released his hands, Kato collapsed onto the mat, face first. Two days after this bout, I saw Helio's students marching down a city street carrying a coffin. They were shouting, "Dead Japanese judoka Kato is in this coffin. He got killed by Helio. We ask your support for Judo Master Helio Gracie!"

After this bout, the popularity of our pro wrestling show declined rapidly. The Japanese whom we encountered on the street murmured, "They must be phonies, losing in such a pathetic manner." Helio issued another challenge, this time to Yamaguchi. Pres. Mizuno of Sao Paulo Newspaper also begged, "Mr. Yamaguchi, please kill Helio, this time." But Yamaguchi seemed reluctant, and asked "Let me think for one night." If he fought a judo match under the Japanese rule, Yamaguchi is superior to Helio both in Tachi-waza and Newaza. But under the Brazilian rule, if Helio got pinned on the ground, all he has to do is to stay calm and be cautious not to get caught in a choke or joint lock, and remain still till the time runs out. Helio could fight to a draw in this way. If he used this tactics, it would be difficult for Yamaguchi to make Helio surrender. I then said to Yamaguchi, "Do not bother to come up with a plan to make Helio submit. I will accept the challenge." Until the day of the bout, we continued pro wrestling shows every other day. 3 days before the bout, local newspaper had a big headline, saying "Kimura is not a Japanese. He seems to be a Cambodian. Helio cannot fight a fake Japanese." I was surprised to see it. I rushed to the Embassy of Japan with my passport, and got a proof that I am a Japanese.

20,000 people came to see the bout including President of Brazil. Helio was 180cm and 80kg. When I entered the stadium, I found a coffin. I asked what it was. I was told, "This is for Kimura. Helio brought this in." It was so funny that I almost burst into laughter. As I approached the ring, raw eggs were thrown at me. The gong rang. Helio grabbed me in both lapels, and attacked me with O-soto-gari and Kouchi-gari. But they did not move me at all. Now it's my turn. I blew him away up in the air by O-uchi-gari, Harai-goshi, Uchimata, Ippon-seoi. At about 10 minute mark, I threw him by O-soto-gari. I intended to cause a concussion. But since the mat was so soft that it did not have much impact on him. While continuing to throw him, I was thinking of a finishing method. I threw him by O-soto-gari again. As soon as Helio fell, I pinned him by Kuzure-kami-shiho-gatame. I held still for 2 or 3 minutes, and then tried to smother him by belly. Helio shook his head trying to breathe. He could not take it any longer, and tried to push up my body extending his left arm. That moment, I grabbed his left wrist with my right hand, and twisted up his arm. I applied Udegarami. I thought he would surrender immediately. But Helio would not tap the mat. I had no choice but keep on twisting the arm. The stadium became quiet. The bone of his arm was coming close to the breaking point. Finally, the sound of bone breaking echoed throughout the stadium. Helio still did not surrender. His left arm was already powerless. Under this rule, I had no choice but twist the arm again. There was plenty of time left. I twisted the left arm again. Another bone was broken. Helio still did not tap. When I tried to twist the arm once more, a white towel was thrown in. I won by TKO. My hand was raised high. Japanese Brazilians rushed into the ring and tossed me up in the air. On the other hand, Helio let his left arm hang and looked very sad withstanding the pain.
