mainly done for practical reasons. One is that the teacher can see how the student positions his or her legs and feet. Another reason is that the teacher and students can quickly see whom to call upon for assistance. In more traditional groups, everyone wears hakama. Kihon Basic technique and movements are shown in the table below. Traditional kata The following five classical or orthodox kata are the only ones practiced in Japan today and were established in this order by the time of Yamada Heizaemon Ippusai in the late 17th century. Instead of the extension 'no kata', the kata in Yamada's book have the extension 'no bu' (之部), which means section (of this book). Kimiyoshi Suzuki's students in Shinbukan also practice these classical katas and this lineage practises its own set of katas preparing for the classical ones. Hōjō The Hōjō no kata (法定之形) is the first classic kata of the Jikishinkage-ryū style and can be translated as laws, rules or methods ('principals') (which are) definitive, crucial or stable ('fundamental') or fundamental principals, i.e. the basics. Both the shidachi and the uchidachi usually use wooden swords, bokken (木剣) or bokutō (木刀), although real swords, shinken (真剣), can be used as well. The Hōjō no kata is composed of four stages which are named after the four seasons, namely haru (春) spring, natsu (夏) summer, aki (秋) autumn and fuyu (冬) winter in order of execution. Each season contains from six to eight waza (movement). Before each season is executed the kamihanen, and after each season, the shimohanen. Each season has a respective pace, kōan (公案) theme, footwork, breathing, kiai, and other features reminiscent of the perceived characteristics of that season. Spring has waza which are executed in a smooth and fast manner, accompanied by loud kiai. The kōan of spring is eight-directions explosive-blast which can be translated as all directions. Summer has movements that are explosive and intense. The kōan of summer is one-sword both-cut which can be translated as cutting your ego. Autumn has a varied pace, symbolizing change. The kōan of autumn is right-turn left-turn which can be translated as times of change. Winter movements are slow, reserved but firm and efficient. This is even more accentuated on the footwork of each season. The kōan of winter is long-short one-body. The following example is an illustration of this principle. Imagine a situation where one person has a
