Sword Related Accidents

Compiled and Edited by Nathan Scott



Are You an Asset or Liability to Japanese Sword Arts (JSA)?

Sword safety is quite a serious subject. For some reason, certain exponents of unrelated arts like karate, tae kwon do, kumdo, hapkido and others have become notorious for consistently embarrassing themselves and those that do seriously study Japanese swordsmanship by performing what can only be described as unnecessary, public stunts of stupidity. Often times, Japanese swords have no historical relationship to their art. Their obvious lack of formal qualified training in Japanese swordsmanship shows clearly during public demonstrations such as the ones listed below, reeking of ignorance and poor judgment. Many of these acts are simply irresponsible, and nothing short of offensive to their own art, swordsmiths, Japanese culture, and most importantly - those that sincerely follow the way of the sword.

The Japanese sword is not simply viewed as "another weapon" in Japan; in the past or the present. Following are some brief references that hopefully provide some insight into how the sword is viewed in Japanese society.

In the earliest written records of Japanese history, the sword is said to have
been one of three objects that played a very important pivotal role in it's mythical
history and the development of the Shinto belief system:



The Sanshu no Jingi are considered core symbols of the Shinto belief system, as well as the symbols of authority and legitimacy for the presiding Emperor of Japan.

Shinto rituals are still included in the forging of new nihonto by traditional smiths, as well as by many traditional martial ryu-ha before and after training. Despite the changes in battlefield tactics and strategy over the centuries of civil wars in Japan, the sword still served as the central weapon of study, which is why even today, instructors of many Japanese martial arts still insist that swordsmanship should be studied at some point to more deeply understand their own art. Japan has historically depended on the sword both literally and figuratively over the years as a symbol of power, virtue, justice - and historically, as the symbol of the samurai class (daisho).

Even in modern times, there can still be found numerous Japanese sayings and anecdotes that refer to the Japanese sword. For example, to do something "shinken" (real sword) means to approach an endeavor as seriously as if you were handling a live blade. "Shinogi wo kezuru/kezutte" (shaving the ridgeline) is to fight furiously, or, to walk the narrow line. "Saya ate", striking another persons scabbard with your own, indicates a rivalry (traditionally resulting in an immediate duel should proper apologies not be offered). "Seppa ga tsumaru/tsumatte" (sword spacers packed together) refers to being compelled by necessity, or driven into a tight corner. "Sori ga awanai" (incorrect sword curvature) is to not get along well with another person. "Moto no saya ni osamatta" means to make up after a quarrel and be reunited. These types of sword references remain in use by modern Japanese even though the practical need for swordsmanship has long since past.

There have been many generations of kenshi that have devoted their entire lives towards preserving and transmitting the methods, virtues and philosophy of Japanese swordsmanship. Such individuals tend to take these matters very seriously. Hopefully this brief overview of the sword in Japanese culture will help to illustrate the necessity for proper instruction, etiquette and respect with regards to Japanese swords and their use.

Accidents can happen to anyone, but the types of incidents listed below are reproduced here because they all could have been avoided through discretion, experience and/or proper instruction in swordsmanship. These examples involve individuals with martial art and/or sword training that became involved in irresponsible public acts, and in some cases, criminal acts. Though not all incidents recorded below involve Japanese swords, it is the author's belief that sword accidents by exponents of any style of sword art will negatively affect all others training in swordsmanship in the eye of the public. This page is published in hopes of encouraging others to act responsibly with good judgement when such choices and decisions present themselves.

PLEASE seek qualified instruction in swordsmanship before attempting to wield a sword - especially around other people.
