We all know the meaning of the word kata. Even to nonpractitioners it is a familiar karate practice. Plus, the word has long been incorporated into the English language. For this reason I choose to write the plural as “katas,” and not follow the Japanese tradition where “kata” can be both singular or plural. By doing this I’ve ruffled feathers already, since many hold such a sacred bond with the time and place where karate took shape. Trouble with one word? Now how about the whole Okinawan martial tradition as passed on through katas? A kata is much like a family jewel that has passed down through generations. It holds a significance that is difficult to decipher, and many dispute the meaning of every micromovement it contains. Who created it? What are the applications? Is kata practice outdated? Is there more than we can see and understand? You bet. It is precisely because of the confusion and misunderstandings regarding the place of kata in the karate tradition that we are thrilled to present a two-volume e-book on this subject. If katas are learning tools that pass down knowledge of a valued art, then the authors included in this anthology can certainly facilitate the learning process for all interested in karate. Each author has excellent experience in the field, having studied directly under masters, often on the largest island in the Ryukyu island chain. In addition to their long years of physical participation in the school of hard knocks, their depth of scholarly research into the encompassing culture allows their writings to illuminate many aspects of kata practice that normally go unnoticed. In our quest to better understand the full significance of kata practice, we must take a serious look at why old masters formulated the routines. How can kata practice better our health and promise to hone our self-defense skills? Each chapter in this anthology deals with the principles that guide kata practice. Hopefully the reading will reveal some of the secrets to improving techniques. As with other martial traditions, some insights cannot be shared through written word. Like good teachers, may the chapters here inspire you to look deeper into kata practice.
