Yoseikan Aikido (養正館合気道 Yoseikan Aikidō) is the aikido taught at the Yoseikan Dojo in Shizuoka, Japan, under the direction of Minoru Mochizuki (望月 稔 Mōchizuki Minoru, 1907–2003).
Mochizuki was a direct student of aikido's founder, Morihei Ueshiba. He was an uchi deshi (live-in student) from around November 1930, to around August 1931. Mochizuki maintained contact with Ueshiba until the latter's death in 1969.
In the 1970s Yoseikan Aikido was formally organised into Yoseikan Budo along with the other arts Mochizuki had studied and mastered, including judo, karate, Tenshin Shoden Katori Shinto-ryu, jujutsu, kobudo, iaido, kendo, jojutsu, and Mongolian kempo. However, some dojos still exist throughout the world that maintain their art as Aikido, and as such, still refer to it as Yoseikan Aikido, or Yoseikan Aikijujutsu/ Aikijutsu.
