He was appointed to the staff of the newly established Kenkoku University in what was then Shinkyo (present-day Changchun).

Rinjiro Shirata, one of Ueshiba’s best prewar students, was originally selected for the Kenkoku University post, but was forced to bow out following his conscription into the Japanese Imperial Army in 1937.
Largely through Tomiki’s efforts, aiki training become a compulsory subject for students of judo and kendo at the University, and he sent for his close associate Hideo Oba, then a 5th dan, from Akita in order to develop a teaching staff. Also, Morihei Ueshiba made regular fall trips to Manchuria during these years to conduct classes at Kenkoku University. Professor Tomiki made great strides during the Manchuria years in fleshing out his theory of rikaku taisei. This term refers to the use of techniques for dealing with attacks by an opponent separated from the defender. This was part of Tomiki’s view of a “complete judo” which encompassed two parts: “grappling judo” (kumi judo) which equated to Kodokan Judo, and “separated judo” (hanare judo) which was equivalent to aikido.

On February 26, 1958, as a result of Tomiki’s efforts, Waseda University approved the creation of an aikido club, one of the conditions being that a method of competition be developed. Together with the members of the aikido club, he devised a form of competitive sparring where an attacker wielding a dagger attempted to score points against a weaponless adversary. It was this action on the part of Tomiki of attempting to convert aikido into a sport that led to a schism with the Aikikai around this time. Tomiki was urged by the Aikikai to adopt a different name for his art other than “aikido” if he intended to introduce such a system of competition. Convinced of the need to modernize aikido, he stood his ground and persisted in his efforts to develop a viable form of competition. He did, however, refer to his art in this period as “Shin Aikido.”
