In 1984 David Dangerfield had his first encounter with Aikido. On seeing a demonstration, he was instantly attracted by the formal and structured nature of the art, combined with its visual beauty and obvious potential effectiveness. David had already been training in various martial arts since 1974, including Shotokan Karate & Chinese boxing and had gained experience in the security industry. In 1986 he began training in Aikikai style Aikido. He learned from various instructors, most memorable were occasional seminars with Takeda Sensei. In 1990 he attained his Shodan (first degree black belt).

In 1991 Dangerfield commenced his study of Yoshinkan Aikido with Joe Thambu Shihan of Aikido Shudokan.Dangerfield officially founded The Aikido Institute Inc as a non-profit martial arts education organisation on the Sunshine Coast in Queensland in 1991. The Aikido Institute was a full-time Dojo providing Alternative Education programmes based on Aikido for young people in local schools. Dangerfield achieved his Nidan (second degree black belt) in 1993. It was around this time that Dangerfield began to travel to Japan to further his understanding of Aikido and Budo in general. He traveled twice a year to Japan on month long training trips where he studied at the Yoshinkan Hombu dojo, training under Inoue Kyoichi Sensei and Chida Tsutomu Sensei. He also made occasional trips to the Aikikai hombu dojo in Tokyo and several trips to Iwama, where he trai ned with Saito Morihiro Sensei.

In 1996 Dangerfield was awarded his Sandan, by this time he had already been teaching for 4 years full-time. In 1997 Dangerfield met Nishioka Tsuneo Sensei, a senior master of Shintō Musō-ryū. This meeting had a great impact on Dangerfield and he found that his personal direction and ‘style’ became clearer. 2000 marked the year that he was accepted as Nishioka Sensei’s student and furthered his studies in this Kobudo.

In 2003 Nishioka Sensei awarded Dangerfield Oku Iri Sho and in 2006 he became one of a small number of people to receive the traditional certification ‘Shomokuroku’ from Nishioka Sensei. In the same year he received his Yondan (4th degree black belt) in Yoshinkan Aikido. Most recently Dangerfield was promoted to Rokudan (6th degree black belt) in the art of Aikido at the 100 years of Aikido celebrations in Malaysia 2012.
