It is widely known that competitive aikido was created by Kenji Tomiki (1900-1979). His hard work and research in the latter years of his life concluded in the creation of a systematic practice method for randori in aikido.
This book describes this practice system, from the basics to application, along with an explanation of the underlying principles and a clarification of the historical and theoretical foundations of competitive aikido.
The result is a detailed work of reference that will not only benefit your randori practice but will improve your level of kata and give you a deeper insight into aikido in general.
