Koryu Aikido Book by Nobuyoshi Higashi

There are many techniques which cannot be fully executed in free practice (randori). Professor Tomiki classified and developed the most effective use of 50 of these techniques from traditional Jujutsu and Aikido. He called these Koryu Goshin no Kara (Self defense form of traditional Aikido). Koryu goshin no kata demonstrates defense against an armed or unarmed opponent. 

Koryu goshin no kata is an essential form of Tomiki Aikido. These techniques are all related to randori no kata (the basic techniques of free practice). 

This is a highly sophisticated form of Aikido. Beginning and advanced students alike will benefit from learning this form correctly to further refine their skills and develop proper technique.
