Aikido

Aikido (合気道， aikidō) is a modern Japanese martial art (gendai budō) founded in the early twentieth century by Morihei Ueshiba (1883–1969), who synthesized techniques drawn principally from classical jujutsu—especially Daitō-ryū aiki-jūjutsu—with his own philosophical and spiritual convictions. Characterized by circular and spiraling movements, joint locks, and throws that redirect an attacker's momentum rather than oppose it with brute force, aikido seeks to neutralize aggression while minimizing injury to the attacker. This aim reflects Ueshiba's vision of martial practice as a path of personal refinement and social harmony, and it distinguishes aikido from many combative arts. Today aikido is practiced in dojos on every inhabited continent, and estimates commonly place the number of practitioners worldwide at over one million.

Etymology

The Japanese name is written with three characters: 合 (ai), meaning "to join," "unite," or "harmonize"; 気 (ki), denoting "spirit," "energy," or "vital force"; and 道 (dō), meaning "way" or "path." The term is often rendered as "the way of harmonizing with the spirit" or "the way of blending energy." The concept of aiki predates Ueshiba and appears in classical jujutsu lineages such as the Daitō-ryū, where it referred to subtly joining with an opponent's movement and intention in order to control him. Ueshiba used various names for his teaching—including aiki-jūjutsu, Ueshiba-ryū, and aiki-budō—before the name "aikido" came into general use around 1942, when it was adopted in connection with organizational reclassification under the Dai Nippon Butoku-kai, the prewar governing body of Japanese martial arts.

Historical Origins and the Founding by Morihei Ueshiba

Morihei Ueshiba was born on December 14, 1883, in Tanabe, in present-day Wakayama Prefecture. A slight and often frail child, he took up martial study as a youth. Over the following decades he trained in several traditions: Tenjin Shin'yō-ryū jujutsu under Tozawa Tokusaburō in Tokyo (from about 1901), Yagyū Shingan-ryū under Nakai Masakatsu in Sakai, and judo under Kiyoichi Takagi in Tanabe. The decisive influence, however, came in 1915, when he met the celebrated jujutsu master Sokaku Takeda in Hokkaido and began intensive study of the Daitō-ryū; Ueshiba received teaching certificates in the art and later became one of its most prominent students.

A second formative influence was his involvement from 1919 with the Ōmoto-kyō new religion in Ayabe, Kyoto Prefecture, and especially his relationship with its charismatic leader Onisaburo Deguchi. Through Ōmoto-kyō, Ueshiba absorbed ideals of universal peace, spiritual purification, and the unity of humanity, which reshaped his understanding of the purpose of martial arts. He taught in Ayabe in the early 1920s, moved to Tokyo in 1927, and in 1931 established the Kobukan Dojo in the Wakamatsu-chō district of Shinjuku, which served as the art's principal center in the prewar years.

During this period his art evolved substantially. Ueshiba's technical repertoire shifted from the harder, more combative jujutsu of his early training toward movements of greater
