Progressive Aikido

A practical guide—written by the grandson of the founder of Aikido—for those seeking greater understanding of both the basic forms and advanced techniques.

Aikido was developed by Morihei Ueshiba, who drew on Japan’s rich history of martial arts to develop an entirely new system that preserves the classical tradition within a contemporary context. In Progressive Aikido, Moriteru Ueshiba, the grandson of the founder and the third Doshu (living symbol and embodiment of the spirit of Aikido), focuses on the most fundamental principle of Aikido: proper movement. Using hundreds of photographs and readily accessible explanations, Ueshiba shows how this crucial technique is the basis for all training, whether as a beginner or as a senior instructor. The book is based on a systematic, step-by-step approach that emphasizes proper movement to train in a range of Aikido techniques, from basic to advanced.

Standard and Primary covers are widely available through general retailers. They often have higher print runs and can be cheaper, especially during sales.

In contrast, Direct Market (DM) and variant covers are primarily sold in comic shops. DM editions tend to have more limited availability and may be more valuable to collectors.

The main differences lie in artwork style, availability, price, and collector appeal. Ultimately, the choice between standard and variant covers depends on personal preference, budget, and individual collecting goals.
