nature of real budo. While it is perfectly understandable that your average parent would not want his or her child actually learning how to kill, it must be understood that these arts were not created for the purpose of entertainment or for sport or for self-improvement—they certainly were not intended for children. The martial arts were intended to train soldiers in how to do their jobs, just as modern militaries train their recruits in the use of the rifle, bayonet, and grenade. The purpose of this book is to introduce you to the teachings of only one small piece of that life-and-death world of budo.
The word shuriken (shoo-ree-ken: The Japanese “r” sounds like a soft “d”) is a Japanese term for small pieces of metal used as throwing weapons. They appear quite often in films and on TV, so it’s unlikely that anyone would not recognize their basic form and function, even if it’s only at a superficial level.
Shuriken-jutsu means “hand release blade techniques.” It entails using shuriken in combat, primarily by throwing, but also by cutting or thrusting. For a long time, the practice of throwing shuriken has been most commonly associated with the ninja, but they were not the only users of these weapons. In fact, every Japanese school of martial arts has had, at some point in its history, at least one form of shuriken-jutsu in their teachings.
As a matter of fact, these weapons are not entirely unknown in the west. During the First World War, similar weapons were used as “bomblets” dropped by the hundreds from aircraft over enemy troops.
It is thought that some of the earliest Japanese practices of shuriken-jutsu were examples of warriors throwing their short swords in battle. The samurai carried two or three swords: a long sword, a short sword and a dagger. The odds of striking a fatal blow against an armored opponent by throwing a short sword are very low. It was an unlikely maneuver, but not totally without merit, as practice in throwing the short sword became common. In some cases, even the long sword was thrown.
The shuriken was never a weapon of great strategic importance to an army on the battlefield. During the Warring States period (1450 to 1600 AD), as in many other countries, battles were fought by large, strategically directed formations of men using weapons of distance.
When thousands of men joined in combat, weapons of range made the strategic difference. Long-distance weapons (cannon, firearms and the bow) were the great killers in feudal Japan (along with deliberately set fires). Formations fired on enemy formations; so combat was not typically man-to-man. Cannons would start the battle and then muskets and bows were employed. The ability to kill at a distance is the secret to survival in war. Cavalry and long spear formations would move around and basically finish the battle. Some of those spears were as long as 18 feet. Even though the spear was a hand-held weapon, it still provided the advantage of killing at a distance.
For those who were lucky enough to carry them, the firearm was the un-disputed supreme weapon. It had the range and power to kill that far exceeded the bow. The bow, however, was the main weapon before the arrival of firearms and continued to be used in great numbers even after the match-lock rifle appeared in battle. Once the sides closed and the advantage of the gun or bow was lost, armies fought with long spears. However, if a soldier lost his spear, he was in trouble, now he no longer had the ability to strike from a distance.
There are many pole arms that provide some distance, but in facing a line of thousands of long spears, only another long spear will be of use. There is a point, however, where an enemy gets too close for even a spear to be useful. There are a number of situations where an enemy can reach you before you can reload your musket or nock another arrow. This distance is the traditional domain of the sword, but it is also the domain of the shuriken.
One could say the shuriken was of great importance to an individual soldier on the battlefield, especially if he were to find himself on the losing side. Once the battle was clearly decided, the losers had three choices: be killed, be captured or escape. At this point, the possibility for close-quarters single combat was a distinct possibility. As the distance between combatants closed and their options ran out, the losing side had no choice but to resort to individual, last-ditch techniques. Such circumstances give rise to an artistic level of survival-inspired creativity. A soldier could find many possible weapons in the litter of a fresh battlefield—weapons lying on the ground or protruding from bodies like broken spears, broken swords, discarded knives, thousands of broken arrows, and pieces of broken armor plate. This may be why Tatsumi Ryu shuriken bear a very strong resemblance to a traditional Japanese yari (spear head).
Any of these battlefield remnants could be used as a buki (weapon) or as me-tsubushi (blinder/distraction). As a soldier on the losing side, all you had to do to survive was get off the field of battle and run. Even if you did not manage to kill your attackers, a distraction, a chance to escape would be enough. The chances of survival are much greater for the man who decides to distract his enemy and escape than for the man who decides to engage in combat.
After the age of wars there came a time of peace known as the Edo period (1600 to 1868 AD). The Edo period is called a peaceful period because there were no more great battles and widespread warring, but that does not mean that individuals were no longer fighting and killing other individuals with regularity. Many of the existing schools of martial arts were founded during the early Edo period. Often these schools “tested” each other by dueling, sometimes to the death, for the honor of their school. The early Edo period also saw thousands and thousands of suddenly unemployed soldiers roaming the countryside who had no other means of making a living. No longer were the fighting men confined to battlefields. During this time of “peace,” the potential for violence to individuals was possibly higher than during the age of wars. Crime was everywhere and there were few police officers. During the early Edo period, the Japanese people started to rebuild their country and grew wealthy, but violence and the fear of violence never left them. The practice of carrying (and using) concealed weapons became commonplace with men and women. There is a story from this period of the famous swordsman Musashi throwing his sword at an opponent. Musashi was losing a duel and was facing death. Were it not for shuriken-jutsu, the man reputed to be “the world’s greatest swordsman” would have been killed by a master of the kusarigama (chain and sickle). He was not the first or last warrior to do this.
Even today, training in shuriken-jutsu is tied closely to the use of the sword. Shuriken are usually thrown before or during the drawing of the sword or they are thrown during a sword fight as a surprise attack. There are even some shuriken designed to be held between the hand and the sword itself, making it easy to use both at the same time. Some martial arts schools consider the kozuka (by-knife) that is carried in the saya (scabbard) of the katana to be their only type of shuriken.
During the Warring States period and Edo periods, an incredible amount of creativity occurred with regard to weapons design and methods of concealing them. Every conceivable form of hand-held weapon found use in Japan at this time. Smaller, more concealable weapons, like the shuriken, were exploited and employed to a great extent. New schools were created and new shuriken designs and methods of hiding them on the body were developed.
Meifu Shinkage Ryu
The Meifu Shinkage Ryu is primarily a bo shuriken school. As such, we will only be discussing in depth the bo shuriken throw. There are two throwing techniques: the basic throw and the advanced throw. The basic throw will enable you to throw the shuriken and stick it in the target reliably and accurately. Compared to the advanced throw it is relatively slow and obvious,
