Having started Aikido under Shioda Sensei in 1969, Tsutomu Chida Sensei is renowned for amazingly fluid and effortlessly masterful technique. He was previously the Chief Instructor (Dojocho) of the Yoshinkan and was the longest serving uchi-deshi under Gozo Shioda Sensei. He is widely recognised as a living legend of Aikido. In January 2008, due to numerous developments Chida Sensei decided to establish his own organisation dedicated to the teaching and dissemination of the Aikido of Gozo Shioda. His organisation is called Aikido Renshinkai.
