Aiki
Japanese name
Hiragana	あいき
Kyūjitai	合氣
Shinjitai	合気
Transcriptions Revised Hepburn aiki

Aiki from a Japanese budo term, at its most basic is a principle that allows a conditioned practitioner to negate or redirect an opponent's power on contact. When applied, the Aiki practitioner controls the actions of the attacker with minimal effort and with a distinct absence of muscular tension usually associated with physical effort.

Etymology

In Japanese Aiki is formed from two kanji:

• 合 - ai - joining
• 氣 - ki - spirit

The kanji for "ai" is made of three radicals, "join", "one" and "mouth". Hence, "ai" symbolizes things coming together, merging. Aiki should not be confused with "wa" which refers to harmony. The kanji for "ki" represents a pot filled with steaming rice and a lid on it. Hence, "ki" symbolizes energy (in the body).

Thus aiki's meaning is to fit, join, or combine energy. However, care must be taken about the absolute meanings of words when discussing concepts derived from other cultures and expressed in different languages. This is particularly true when the words we use today have been derived from symbols, in this case, Chinese and Japanese kanji, which represent ideas rather than literal translations of the components. Historical use of a term can influence meanings and be passed down by those wishing to illustrate ideas with the best word or phrase available to them. In this way, there may be a divergence of the meaning between arts or schools within the same art. The characters "ai" and "ki" have translations to many different English words.

Historically, the principle of aiki would be primarily transmitted orally, as such teachings were often a closely guarded secret. In modern times, the description of the concept varies from the physical ^[1] to vague and open-ended, or more concerned with spiritual aspects.

Aiki martial arts

Aiki lends its name to various Japanese martial arts most notably Aikido and its parent art, Daito-ryu aiki-jujutsu. These arts tend to use the principle of aiki as a core element underpinning the bulk of their techniques. Aiki is an important principle in several other arts such as Kito-ryu and various forms of kenjutsu and is found as a concept in other many Chinese internal arts like tai-chi, hsing-i, bagua among others although the term aiki is not commonly referenced in non-Japanese cultures.^[2] Techniques accomplished with aiki are subtle and require little mechanical force with the Aiki arts generally classed as soft internal martial arts.

The concept of Aiki

Aiki is a complex concept, and three aspects have been used to describe it in relation to a martial situation:

1) Blending not clashing

Aiki typically describes an idea of oneness or blending in the midst of combat. In aikido it generally describes the more elevated notion of blending rather than clashing. "Blending" is often described even within aikido as "awase".^[3] Many definitions for "aiki" seem to be based around "awase". Emphasis is upon joining with the rhythm and intent of the opponent in order to find the optimal position and timing with which to apply force. To blend with an attack, many believe it is necessary to yield to incoming forces but basic practitioners of aiki understand that there is a difference between 'blending' and 'giving way', and they instead train to 'take the line' of attack subtly and control it. Aiki is closely related to the principle of ju though the latter places more emphasis on the active physical manipulation on a mechanical structural level.

2) Leading the assailant

The aiki practitioner is able to lead the attack, and thus the attacker, into precarious positions. The influence over an assailant grows as the assailant's balance deteriorates. Body movements (tai sabaki) used for this may be large and obvious or small and subtle, internally generated movements. Subtle weight shifting and the application of physical pressure to the assailant enable one to lead an assailant, keep them static, or keep them unbalanced (kuzushi) in order to employ one’s own technique. In the same manner, through deceptive movements, the aiki practitioner may negate a defence response from the assailant or create a defence response from the assailant that puts them even further into peril. There is a strong degree of intent, will or psychology^[4] to this aspect of domination. Mind and body are coordinated.

3) Use of internal strength - Ki energy

Kiai and aiki use the same kanji (transposed) and can be thought of as the inner and the outer aspect of the same principle. Kiai relates to the manifestation, emission or projection of one's own energy externally (external strength), while Aiki relates to one's own energy internally (internal strength). Thus kiai is union of external energies while aiki is union of internal energies. This use of ki will involve the use of kokyu power, i.e. breathing is coordinated with movement.^[5] Kokyu Ryoku is the natural power that can be produced when body and consciousness (mind) are unified. The term "kokyu" can also be used to describe a situation in which two opponent's are moving with appropriate timing.

Thoughts on aiki

Aiki is considered to be an ancient practice, and it's practice often kept within a particular individual or two from a family/school lineage. Culturally, and due to certain necessities of the time period, the aiki knowledge was usually a very well guarded secret and rarely disclosed.

The oldest book to have historically discuss aiki was the 1899 Budo Hiketsu-Aiki no Jutsu. On the subject of aiki it was written:

The Textbook of Jujutsu (Jujutsu Kyoju-sho Ryu no Maki) from 1913 wrote:
