Aikido was developed by Morihei Ueshiba, who studied a number of martial arts. One of these was Dai To Ryu Aki Jujitsu, which was derived from the secret teachings of the Takeda samurai clan. Ueshiba Sensei synthesized several martial arts to create modern Aikido. One of Ueshiba's greatest students was Gozo Shioda. He had first studied judo from a very young age in his father's dojo called the "Yoshinkan" - or "House of Cultivating Spirit" Soke Shioda eventually started the Yoshinkan style, which maintained the original 'martial' aspects of Aikido. Yoshinkan Aikido is taught throughout Japan and the world. Members of the RCMP, the Tokyo Riot Police and other forces train in Yoshinkan Aikido. Yoshinkan Aikido is for everyone, allowing practitioners to train at their own pace and intensity. With proper effort and training, it is an extremely effective form of self-defense.
