Aikido Terms

Aikido Terms

Aikido = the way of Harmony of the Spirit AIKIDO

Ai=  Harmony      Ki= Spirit         Do= Way

The pronunciation of Japanese words tends to be somewhat subject to interpretation. Do not be confused by minor differences. Japanese speakers are.

A little effort in learning this vocabulary can add much to one’s ability to learn and understand Aikido.  Japanese terminology is always used in teaching Aikido for two reasons;  First, it helps to preserve the traditional heritage of Japanese martial arts; and second, it provides/establishes a common language understandable to all Aikidoka around the world, regardless of their primary language or culture.

The consonants of Japanese are usually pronounced like those in the English language. Vowels are pronounced as follows:

A“ah” as the a in father

E“eh”as the e in met

I“ee” as the i in marine …(Irimi – ee/ree/mee)

O“oh”as the o in oboe

U“oo”as the u in rule … Uke (oo/keh)

Definition / Shindai:

To conduct oneself in awareness of the divine nature of those around us. To walk in the appreciation of the precious aspects of all life, with consideration for all. Taken from the Kojiki the word Shindai derives itself  from a time when men and gods walked the earth together. Indistinguishable from one another, one therefore conducted oneself as if everyone was a god. Consideration, empathy, respect, honor, a nurturing nature, ethics, an attitude of chivalry, a strong spirit, all of these things were the nature and second nature of all. This is Shindai.
