Sanchin (サンチン Sanchin ) is a kata of Southern Chinese (Fujianese) origin that is considered to be the core of several styles, the most well-known being the Okinawan Karate styles of Goju Ryu and Uechi Ryu, as well as the Chinese martial arts of Fujian White Crane, Five Ancestors, Pangai-noon and the Tiger-Crane Combination style associated with Ang Lian-Huat. Tam Hon taught a style that was called simply "Saam Jin" (Cantonese for "Sanchin"). The name Sanchin, meaning three battles, is sometimes interpreted as the battle to unify the mind, body, and spirit; there are other interpretations of it, however.
The version of Sanchin used by most styles of Karate was developed by Goju Ryu founder Chōjun Miyagi and uses a very strong, tense closed fist "push". In Uechi Ryu and in Ryusei, the practice of Sanchin is closer to the Chinese version with faster spear hand strikes a little snake like.
Only one stance is used—the sanchin (meaning "three battles") stance, from which a name of the kata is derivative now (initially it was named as Peppuren 1. Sanchin-dachi is a practical stance, and yet is the most difficult stance to master. The legs protect the body from sweep kicks, the thighs are to trap low kicks. According to a tai chi manual ("Zhengzi 13 postures"), the punch draws its power from the earth through the legs—the flip of the hips enables the strength of the whole body to be channeled and focused into one punch.
Properly employed, Sanchin kata follows the "hard" style of karate—all the muscles are to be flexed and tensed throughout the kata—actually making it the most strenuous kata. This type of strength training, is only recently understood in Western science and is known as "isometric training" in bodybuilding.
In Chinese training, Sanchin kata also introduces the student to the use of "qi" (Japanese "ki") for training and fighting applications. It can be understood to be a form of "qigong" as employed in Chinese Wushu. In Qigong the hands are not closed into a fist as it would be deemed as restricting the flow of Chi. The focus in Qigong is on the controlled breathing to generate Chi in the body. Many western interpretations of qi/ki explain it as an enhanced understanding of internal body dynamics and muscle control through repeated and strenuous training.
In Gōjū, there are two sanchin kata: the first one, Miyagi's sanchin (or "sanchin dai ichi"), the most widely taught as initial and Kihongata, was created for such purpose by Chojun Miyagi, and has no turns so the karateka goes forward and then backwards. The second sanchin, Higashionna's sanchin (or "sanchin dai ni") is a full-version Sanchingata and is older and was taught by Higashionna Kanryo. In this kata the karateka always goes forward, but turns 180 degrees twice. Initially it was taught with open hands, as sanchin-kata still is in Uechi-ryu, but later it was also revised to closed fists by Miyagi's co-student Juhatsu Kyoda, founder of To'on-ryu, and adopted by Chojun Miyagi as well.
Some say the meaning of Sanchin ("Three battles") relates to the three journeys of life; Developing body, mind and spirit. Through proper martial arts training, one properly learns to develop her or his body through exercise and practise of kata/forms. Later, one begins to understand the true meaning of one's training and develops an understanding of bunkai and history, developing the mind. Spirit is developed much later in life and is only understood by those who have achieved this.
The Sanchin routine uses only its namesake stance and is carried out with controlled breathing (ibuki breathing). Inhalation and exhalation are performed in unison with the various blocking and striking movements. In the most commonly taught versions, emphasis is placed on the tension of the practitioners' muscles, and movement of the body as a solid, stable unit. The Chinese and Uechi-Ryu version uses open hands while other Okinawan and Japanese versions tend to use closed fists. Certain schools of Five Ancestors kung fu, most noticeably those hailing from the Chee Kim Thong lineage, employ minimal tension during execution. This is intended to facilitate the correct training of qi (or ki).
The following description does not apply to the Chinese Sānzhàn stance.
The narrow (shoulder width) upright "pigeon-toed" foot position of the Sanchin stance (Japanese: sanchin dachi) balances stability in two directions (front and side) with the flexible waist rotation needed for strong punches and kicks. The toes attempt to "grip" the floor, attempting to turn the feet outward while actually turned inward, creating a rooted stance, whilst the pelvis remains tilted upward along with the turned-in position of the front knee and the bent back knee help protect the groin from kicks.
Some styles use Sanchin as a method of checking strength and posture, as well as concentration. All hits directed towards the karateka are done at the end of the punch, when they are in their most tense position. Most Goju-ryu schools use the following checking procedures:
- Light to heavy slap down on the shoulders. This checks that the shoulders are in a natural position, yet tense.
- Light to heavy strikes (generally a ridge hand) to the lats. This is to check if the lat muscles are tight. Light trapping of the elbows with a hand or fingers check that the karateka is holding proper form with their arms and elbows, and using full strength to strike.
- Checking the legs. From behind, slapping the sides of the knees to make sure the legs and stance are solid.
- Fingers to the back of the neck. This is a reminder to fix posture.
- Groin and pelvic tuck(tilt). From the front or rear, kick or raise arm to the groin. If the karateka is in proper Sanchin stance and the pelvis is tilted, he will trap the kick or arm with the inner thighs.
- Breathing check. Light to heavy striking of the stomach. This could be a standard punch or a ridge hand from the side. This will check for proper ibuki breathing.
- Concentration check. The person performing shime should not strike in a specific pattern, allowing the karateka to anticipate the strikes. He should strike randomly, allowing the karateka to focus on the kata itself and not on the strikes. This may involve occasionally "faking" a strike in view of the karateka to check that he does not react to it. This is a portion of the "mind" part of "mind, body and spirit."
- Posture. Check the strength and posture by hooking, open palmed, the wrists, and guiding the punch, while applying resistance.
In Uechi-Ryu, the practitioner stops the kata for each sequence of shime checks, then the kata starts up again - stopping and starting for each series of checks; as opposed to the kata being done continuously without regard to the person giving shime. Also in Uechi-ryu, the practitioner is open handed and the shime involves roundhouse kicks directed to the legs and occasionally the arms. Shin conditioning is checked by toe-kicks directly to the shins.
Traditional Okinawan schools will vary on their application of shime.
