Jod­an / Chu­dan / Gedan

As a prac­ti­cal­ly ori­en­ta­ted mar­ti­al artist, who trains always with a degree of cont­act in part­ner work, I am used to rea­li­stic reac­tions after an impact. 

I ori­gi­nal­ly trai­ned with my tea­cher, Lud­wig Bin­der, in a full-cont­act-based form of Sho­to­kan Kara­te; sin­ce he had his roots in Yus­hin­kai-full-cont­act-kara­te.  Years later, I found fri­ends in New-York-City. Shi­han Michel­le Gay’s Dojo, KEN-WA-KAN Kara­te Do, is an off­shoot from world-Oya­ma-full-cont­act-kara­te. Last but not least, I beca­me fri­ends with Jür­gen Höl­ler, a prac­ti­tio­ner of Ashi­ha­ra-full cont­act kara­te for around fif­ty-years. The­se trai­ning expe­ri­en­ces have been very influ­en­ti­al on the way I view the dif­fe­rent levels or are­as in kara­te: jod­an, chu­dan and gedan.

Vir­tual­ly every kara­te­ka has heard of the­se clas­si­fi­ca­ti­ons, and most are awa­re what they mean. Typi­cal­ly, we think of jod­an for neck and head, chu­dan for should­ers to pubic-bone, and gedan for the legs and gro­in. Let’s now take a clo­ser look at the­se three terms. When explo­ring the­se terms, I asked mys­elf seve­ral ques­ti­ons.

•             Are we real­ly tal­king about heights?

•             Why were the­se are­as crea­ted and why do we use them?

•             Should we view them from defen­si­ve or offen­si­ve point of view?

•             Are they tra­di­tio­nal­ly or do they ori­gi­na­te is modern sport kara­te? 

•             Whe­re are the demar­ca­ti­ons bet­ween them?

•             Can we bet­ter descri­be and use the­se clas­si­fi­ca­ti­ons?

Exami­ning the sources, I found two main ways of loo­king at the levels. First­ly, the­re are pic­tures with lines on a stan­ding body to divi­de the heights. Second­ly, the­re are texts to explain which part of the ana­to­my are included in each level. Bey­ond that, we don’t have a gre­at deal to go off, so it initi­al­ly seems that defi­ni­ti­ve ans­wers may be hard to come by. Howe­ver, I think we need to look bey­ond the sur­face and exami­ne things more deep­ly.

Jod­an (上段) means “high-level”, chu­dan (中段) means “midd­le-level” and gedan (下段) means “low-level”. This would seem obvious when appli­ed to a stan­ding body, but they can also be appli­ed to a fal­ling or pro­ne body. The­se clas­si­fi­ca­ti­ons are the­r­e­fo­re best seen, not as heights from the flo­or, but as desi­gna­ted are­as on the body. We can view the­se desi­gna­ti­ons from both an offen­si­ve and defen­si­ve per­spec­ti­ve.

From an offen­si­ve per­spec­ti­ve, the ter­mi­no­lo­gy around the three levels can make things easier for ever­yo­ne; stu­dents and tea­cher. We can sim­ply say “jod­an elbow” ins­tead of “elbow strike to the head”. We can say, “strike chu­dan” ins­tead of “deli­ver a strike to the sto­mach”. We can say, “kick gedan” ins­tead of “deli­ver an attack a leg”. Howe­ver, such ins­truc­tions lack pre­cis­i­on and don’t com­mu­ni­ca­te the spe­ci­fic ana­to­mic­al tar­gets or how to best attack them. This is important infor­ma­ti­on and hence the vague natu­re of the terms is poten­ti­al­ly pro­ble­ma­tic.

From a defen­si­ve per­spec­ti­ve, the vague natu­re of the terms can be seen as a posi­ti­ve. You don’t neces­s­a­ri­ly need to have know­ledge of the pre­cise tech­ni­que coming at you in order to stop it. It can be enough to defend a cer­tain area. It would the­r­e­fo­re seem the terms have more value defen­si­ve­ly. Howe­ver, it seems odd to me that the terms are still appli­ed to offen­si­ve tech­ni­ques.  Sure­ly, their wide­spread use that way would sug­gest they must have some value offen­si­ve­ly; bey­ond simp­le con­ve­ni­ence in trai­ning.

From a modern com­pe­ti­ti­ve per­spec­ti­ve, the levels are used pro­hi­bit cer­tain attacks and to desi­gna­te the num­ber of points award­ed for others. This is of litt­le con­cern with regards to this artic­le, becau­se we are con­side­ring things from a tra­di­tio­nal and com­ba­ti­ve per­spec­ti­ve.

As a prac­ti­cal mar­ti­al artist, who has always trai­ned with a degree of cont­act, I have been able to obser­ve how the enemy’s body reacts after any given strike. Tho­se like me will be awa­re that after cont­act the part­ner usual­ly leans back­ward, for­wards or side­ways. I think the three levels can be very hel­pful in deter­mi­ning what the most likely reac­tion will be; and hence what the most appro­pria­te fol­low up attack will be. This is whe­re we find their offen­si­ve value.

I belie­ve the­re is an important line, which isn’t include on the dra­wings that typi­cal­ly show the three levels. This the line from elbow to elbow; just abo­ve the solar ple­xus. This line divi­des the body in such a way we can pre­dict the enemy’s reac­tion after impact. If one was hit abo­ve this line, his body will lean back­wards. As a result, the abdo­mi­nal mus­cles will be stret­ched, and the geni­tals will be vul­nerable to attack. If one is hit below this line, his head will come for­ward and his arms will be posi­tio­ned in front of his sto­mach and chest. Addi­tio­nal­ly, he will bend at the waist such that his backside will move back­ward.

When we have con­side­red this, prac­ti­cal kara­te­ka can best defi­ne the levels as:

Jod­an is abo­ve the elbow-line.

Chu­dan is the lower tor­so.

Gedan is the geni­tals and lower.

To make use of the levels offen­si­ve­ly, we know that if we want the ene­my to lean back­ward, then strike jod­an. Con­ver­se­ly, if you want the enemy’s head to come for­ward, then attack chu­dan. The terms the­r­e­fo­re have offen­si­ve com­ba­ti­ve value in deter­mi­ning the enemy’s reac­tion to impact. 

Defen­si­ve­ly, the­re are also advan­ta­ges to divi­ding the body this way:

Jod­an is this area you can pro­tect with your arms alo­ne.

Chu­dan is the area you can pro­tect with your legs and arms

Gedan is the area you pro­tect with your legs alo­ne.

By moving the jod­an line down from the neck to the elbows, the three levels have both offen­si­ve and defen­si­ve value. I the­r­e­fo­re sug­gest that all prac­ti­cal kara­te­ka join us in defi­ning the levels in this way.
