Aikido ~ (合気道 Aikidō, also 合氣道 using an older style of kanji) Literally meaning “harmony energy way”, or with some poetic license, “way of the harmonious spirit”, is a gendai budo – a modern Japanese martial art. Practitioners of aikido are known as aikidoka. It was developed by Morihei Ueshiba (植芝盛平) (also known by aikidoka as o-sensei (大先生)) over the period of the 1930s to the 1960s. Technically, the major parts of aikido are derived from Daitō-ryū Aiki-jūjutsu (大東流合気柔術), a form of jujutsu with many joint techniques, and kenjutsu (剣術), or Japanese sword technique (some believe the tactics in Aikido are especially influenced by Yagyū Shinkage-ryū). Aikido is also considered to contain a significant spiritual component.
