Over the years, I’ve put out a few articles regarding the importance of working on kihon gata (基本形), or basic techniques, for kobudō, as one would have a difficult road proceeding forward without a solid foundation these develop. Now I want to go into a little about kata (形), or forms with preset movements, which are next in the journey of learning a Japanese martial art. Just like basic techniques, one must take the same approach and work hard on what would be the basic for forms, in order to properly learn the methodology of one’s martial system.

A term found in traditional Japanese systems is “honwaza” (本技). What does honwaza mean? This label is used to identify kata that are base forms. Honwaza is used a good deal when working with kata (形), a well known term for forms used in most of Japanese martial arts. Depending on the martial art school, there may be different terms used to identify forms, such as sei (勢), or gyō (業). In the end, they represent the same concept of forms to learn a school’s methodology.

Why are base forms so important? For starters, they are the vehicles for learning one’s selected martial system; from principles, strategies, to techniques, a base form is constructed as the prime instruction for this. Also, base forms are built on the basic techniques one learns at the start of one’s martial journey, so they become another method of refining those core skills, and enhancing one’s overall ability. Of course, if one’s basics are not cemented properly, then base forms will expose this, for you will find difficulties in performing them as instructed.

Along with base forms, there are “variation” forms that accompany them in order flesh out a student’s understanding of their martial system. Falling under specific terms such as henka (変化), ura gata (裏形), sayū jōge (左右上下), and so on, these variations are taught at different stages depending on when students have achieved an adequate understanding of said base forms. These variation forms are necessary for teaching options in specific situations, from utilizing different movements, techniques, and so forth, adding more tools to one’s repetoire. While there is a lot to be taken from these, understand that they do not replace the importance of base forms. For starters, variation forms, while necessary for further instructions in one’s martial system, may not fully “teach” key methodologies or principles clearly without understanding the original. While some variation forms may differ from the base form in simply a few movements or the technique used to defeat one’s opponent, others may change early in the form and use a strategy that veers away a considerable amount from the original. Then there are those cases where the variation form does not resemble the basic form at all.

Let’s take a kata from Kukishin ryu Bōjutsu called “Sashi Ai” as an example. In the base form, after several sequences, when our opponent raises their sword to strike, we react by crouching low and swinging our bō upwards into our opponent’s lower area. There is a lot to unpack here even just by focusing on this simple movement of taking a low profile against a high strike. Now, let’s compare with a similar version of this kata, but instead we step to the side, and lower one’s stance while thrusting the tip of our bō to the opponent’s face. It can be stated that this alternative movement is equally effective as the base form. However, it deviates by using different movements that change certain key elements, such as distance, timing, and positioning. Alternative movements in a kata like so may not utilize core fundamentals that are part of the identity of a martial art, but instead introduce supplemental lessons in the event a situation changes based on the opponent’s movements, thus why this is labeled as a variation form.

In truth, all versions of kata are important, whether it be the base form or a variation. However, since the base form usually represents the identity of a martial system, full details of it, whether in the form of visuals or specific lessons, may be held back. In its place, a variation can be openly presented…which in turn is a strategic decision of its own. Here’s a scenario to which variation forms are chosen over base forms. During a public demonstration, a school may choose to use a variation form with many changes from the original. This keeps the core principles of the martial system safe, not exposing the key components, so those viewers who see just the variation form and choose to copy it won’t be able to steal the most critical points. From another angle, those same viewers could later turn around and openly declare they too have learned a specific martial system in order to draw unsuspecting students by demonstrating the variation form they saw, saying it’s the real deal. Of course, legitimate schools can expose them as lying, revealing them as frauds.

In ending, the idea of honwaza, or base forms, being a key component of one’s growth in martial arts is on the same level as learning, establishing, and refining one’s foundation through fundamental skills. Base forms can be thought of as a form of treasure, which should be preserved even when you have mastered all that there is to learn in the martial system you dedicate yourself to. While there is no love lost for legitimate schools that present only variation form so long as within inner circles they are acknowledged as truly knowing the original, it still holds true the importance of ensuring that base forms are preserved accurately in order to continue being an essential tool for proper learning.
