Kiyoyuki Terada (寺田精之, March 20, 1922 – July 13, 2009) was a Japanese aikido teacher. He was ranked 10th dan in Yoshinkan Aikido and served as the most senior instructor in Yoshinkan Aikido until his death.
Terada was born in Nagasaki, Kyūshū, Japan. His martial arts life began in April 1934 at Kaisei Junior High School where he took up his first martial art of Kendo. At age 15, he received an award for the best Judo player of the year after winning a Judo championship that same year. Upon his entry into Takushoku University at age 18, he began his karate training. It was there that in 1941 he met Gozo Shioda, the future head of the Yoshinkan Aikido dojo. During the period between 1940 and 1943, Terada learned Sumo from Akutsugawa Sensei, Judo from Sone Sensei, and Kashimaryu Jujitsu from Osugi Sensei.
At age 21 in 1943, Terada joined the Imperial Japanese Army due to the ongoing war. In March 1944 he was ordered to the Japanese Airforce Academy and became an aircraft mechanic. From 1944 to 1945 he worked in aircraft maintenance at Kumamoto Airfield. It was here where he learned that the war had ended and two days later on August 17, he returned home to Nagasaki.
Terada moved to Tokyo in 1948 and worked for the Miyakoshi Company. In 1950 he went to work for the military police in Yokohama. This same year he joined the Aikikai Honbu dojo. His primary teacher was Kisshomaru Ueshiba and he also took lessons from aikido founder, Morihei Ueshiba.
