Kenjutsu (剣術) is the umbrella term for all traditional (koryū) schools of Japanese swordsmanship, in particular those that predate the Meiji Restoration and the modern styles of kendo and iaido that emerged from the traditional schools in the late 19th century. Kenjutsu, which originated with the samurai class of feudal Japan, means "the method, or technique, of the sword." This is opposed to kendo, which means "the way of the sword".

The exact activities and conventions undertaken when practicing kenjutsu vary from school to school, where the word school here refers to the practice, methods, ethics, and metaphysics of a given tradition, yet commonly include practice of battlefield techniques without opponent and techniques where two persons paired kata (featuring full contact strikes to the body in some styles and no body contact strikes permitted in others). Historically schools incorporated sparring under a variety of conditions, from using solid wooden bokutō to use of bamboo sword (shinai) and armor (bogu). In modern times sparring in Japanese swordsmanship is more strongly associated with Kendo.

History

Early development

It is thought likely that the first iron swords were manufactured in Japan in the fourth century, based on technology imported from China via Korean peninsula. While swords clearly played an important cultural and religious role in ancient Japan, it is in the Heian period when the globally recognised curved Japanese sword was developed, and when swords became an important weapon, as well as a symbolic item. No known Kenjutsu lineage survived from this period; the oldest schools still in existence today arose in the Muromachi period (1336 to 1573), known for long periods of inter-state warfare. Three major schools emerged during this period.

• Kage-ryū (Aizu) (Aisukage ryū)
• Chujo-ryū
• Tenshin Shōden Katori Shintō-ryū

These schools form the ancestors for many descendent styles, for example from Ittō ryū has branched Ono-ha Ittō ryū and Mizoguchi-ha Ittō-ryū (among many others). On the island of Okinawa, the art of Motobu Udundi includes a unique method of both Kenjutsu and Iaijutsu. This is the only surviving sword system from Okinawa. It was the martial art of the noble Motobu family during the period of the Ryukyu Kingdom.

Edo Period

During the Edo period schools proliferated to number more than five hundred, and training techniques & equipment advanced. The nineteenth century led to the development of the bamboo practice sword, the shinai, and protective armor, bogu. This allowed practice of full speed techniques in sparring, while reducing risk of serious harm to the practitioner. Prior to this, training in Kenjutsu had consisted mainly of basic technique practice and paired kata, using solid wooden practice swords (bokutō), or live blades.

Decline

Beginning in 1868, the Meiji Restoration led to the breakup of the military class and the modernization of Japan along the lines of western industrial nations. As the samurai class was officially dissolved at this time, kenjutsu fell into decline, an unpopular reminder of the past. This decline continued for approximately twenty years, until rising national confidence led to an increase of the uptake of traditional sword arts again, particularly in the military and the police.

In 1886 the Japanese Police gathered together kata from a variety of kenjutsu schools into a standardised set for training purposes. This process of standardization of martial training continued when, in 1895, a body for martial arts in Japan, the Dai Nippon Butoku Kai, was established. Work on standardizing kenjutsu kata continued for years, with several groups involved, until in 1912 an official edict was released by the Dai Nippon Butoku Kai. This edict highlighted a lack of unity in teaching, and introduced a standard core teaching curriculum to which the individual kenjutsu schools would add their distinctive techniques. This core curriculum, and its ten kata evolved into the modern martial art of kendo. This point could be regarded as the end of the development of kenjutsu and the kenjutsu was transmitted to the modern kendo.

20th and 21st century

With the increasing interest in Japanese martial arts outside Japan during the twentieth century people outside Japan started taking an interest in kenjutsu. Many martial artists who study Japanese martial arts know the principles of kenjutsu. For modern kenjutsu type training most practice is done in suburi style with bokken.

Weapons

One of the more common training weapons is the wooden sword (bokuto or bokken). For various reasons, many schools make use of very specifically designed bokuto, altering its shape, weight and length according to the style's specifications. For example, bokuto used within Yagyū Shinkage-ryū are relatively thin and without a handguard in order to match the school's characteristic approach to combat. Alternatively, Kashima Shin-ryū practitioners use a thicker than average bokuto with no curvature and with a rather large hilt. This of course lends itself well to Kashima Shin-ryū's distinct principles of combat.

Some schools practice with fukuro shinai (a bamboo sword covered with leather or cloth) under circumstances where the student lacks the ability to safely control a bokuto at full speed or as a general safety precaution. In fact, the fukuro shinai dates as far back as the 15th century.

Techniques and styles

Nitōjutsu

A distinguishing feature of many kenjutsu syllabi is the use of a paired katana or daitō and wakizashi or shōtō commonly referred to as nitōjutsu (二刀術, two sword methods). Styles that teach it are called nitōryū (二刀流, two sword school); contrast ittō-ryū (一刀流, one sword school). The most famous exponent of nitōjutsu was Miyamoto Musashi (1584 – 1645), the founder of Hyōhō Niten Ichi-ryū, who advocates it in The Book of Five Rings. Nitōjutsu is not however unique to Hyoho Niten Ichi-ryū, nor was nitōjutsu the creation of Musashi. Both Tenshin Shōden Katori Shinto-ryū were founded in the early Muromachi period (ca. 1447), and Tatsumi-ryu founded Eishō period (1504–1521), contain extensive nitōjutsu curricula while also preceding the establishment of Musashi’s Hyoho Niten Ichi-ryū.

Techniques

Kenjutsu techniques can be compared to the strategies of warfare, while batto-jutsu or kendo can be compared to shooting range techniques. As in the "Book of Five Rings", by Miyamoto Musashi, a kenjutsuist relies on the conditions of the ground, light source, as well as the opponents' capabilities, before implementing a practical attack. The attack is not set on any particular weapon or move to capitulate. Nor is there a predisposed target or trajectory - any exposed part of the opponents body is a possible target (as in Musashi's "Injuring the Corners").

To be effective, a kenjutsu strike/or counter-strike is a composition of several techniques: feigning, cutting, jabbing, thrusting, parrying or binding, footwork, choice of weapon, and even knowing the opponents weapon. It was mentioned that once Musashi realized the physics of the Chain-and-Sickle (kusarigama) that he was able to defeat it.

The feigning techniques are effective movements of the weapon, footwork, center of gravity, and even the use of kiai. Applied effectively, the opponent is set-back one move, while creating an opening elsewhere. The feigning technique should be angled to allow a quick direct shot from this position. Only sufficient amount of practice will perfect these techniques, and whatever method of teaching it takes to convey the training of proper reflexes. There is not much time to think during a skirmish or battle. A fluent continuation of techniques must be deployed in order to manage even multiple opponents. One second per each opponent is too long. Managing an entire army should be treated the same way. A practical understanding of the body and weapon is necessary in order to be able to dispatch a strike or counter strike whether standing, walking, or rolling around the ground, (or whether an army is attacking or retreating). There is no time-out or ready position. It might even be a fight under minimum visibility or even total darkness. When striking range is reached, reflexes dictate the outcome.

Cutting, Jabbing, and thrusting techniques must be all preceded by a feign. The defender can easily parry a strong attack due to the telegraphing momentum behind the attacker's weapon. Therefore, a strong cutting technique can easily receive a deadly cut across the sword hand or forearm. The feigning movement should compliment both double-sword, two-handed sword, or any weapon.

There are some strikes that do not require a preceding subterfuge. These are referred to as "Quick Strikes". They are done with two hands on the sword, or with sword in each hand. One hand is at the base of the tsuka (to provide longer reach), and the other hand is at the ridge of the blade to provide the initial force to flick the sword as quick as an arrow to hit the target. This could also be done with the double sword, with one sword providing the push for the dispatch. These postures are hidden, and the ready positions are implemented while switching hands or while changing steps. These flicking strikes can be administered from any angle (from the top, sides, or below).

When parrying, always try and direct the point of the sword to the target. This minimizes the step needed to be able to counter-attack. Thus, the opponent is at an immediate disadvantage. Also, using the quick strike at the opponents sword hand or forearm will immediately incapacitate the opponent's attack before having to parry it. A simple rule of thumb to keep the point of the sword pointed to the opponent (or at within the area of the gate) while attempting to parry in all angles, will provide a good foundation for an appropriate counter maneuver reflexes.

Musashi had mentioned that the footwork shall be accommodating to whatever terrain or purpose that is given. The correct stride is to be applied to whatever leverage is necessary or needed to effectively wield the weapon on-hand. The choice of weapon and knowing the opponents' weapons is detrimental to the assessment of the right technique and strategy. Knowing the center of gravity of a particular weapon can help the assessment of its maneuverability and speed, as much as its effects on leverage and kinetic forces.

The use of the double-sword (a sword in each hand) can provide an ultimate control of the gate. The "Gate", as referred to by Miyamoto Musashi is the opening between two fighters at a given time. All attacks must go through the gate in order to reach the target from any angle. To close or disrupt the gate at the correct given time is necessary to deflect incoming attacks. The double swords' ability to alternate and compliment their trajectories provide a strong continuous flowing barricade as well as trapping and striking repetitions. Timing is essential in the use of this technique, and Musashi had advised that the double-sword technique should be learned early-on.

In the later stages of kenjutsu, one can win without the use of a blade - by merely understanding on how the physics of sword work. A kenjutsuist can resolve or win without having to fight (or without having to cut) - and gaining followers instead. There is not one individual or certain religion that started this. Any level headed person would not want to maim or kill another human being if he knows that he can do it at will. A kenjutsuist (a true swordsman) strives to attain well beyond cutting techniques - to be able to serve his master or act on his own as a diplomat of fairness in the living hell.
