HistoryEdit

The origins of the bo-shuriken in Japan are still unclear, despite continuing research.

This is partly because shurikenjutsu was a secret art and also due to the fact that throughout early Japanese history there were many independent exponents of the skill of throwing long, thin objects.

The earliest-known reference to a school teaching shurikenjutsu is Ganritsu Ryu, active during the 17th century.

This school utilized a long, thin implement with a bulbous head, thought to be derived from the arrow.

Surviving examples of blades used by this school appear to combine an arrow's shape with that of a needle traditionally used in Japanese leatherwork and armor manufacture.<ref name="mol" />

There are earlier mentions in written records,Template:Clarify such as the Template:Nihongo3, of the standard knife and short sword being thrown in battle.

Miyamoto Musashi is said to have won a duel by throwing his short sword at his opponent, killing him.

TypesEdit

Shuriken are also known as throwing stars, or ninja stars, although they were originally constructed in many different shapes.

Bo-shurikenEdit

A Template:Nihongo3 is a throwing weapon consisting of a straight iron or steel spike, usually four-sided but sometimes round or octagonal in section. Some examples have points on both ends.

The length ranges from Template:Convert and the average weight from Template:Convert.<ref name="mol">Template:Cite book</ref> They should not be confused with the kunai, which is a thrusting and stabbing implement that is sometimes thrown.

Bo-shuriken were constructed from a wide variety of everyday items, and as such came in many shapes and sizes.

Some derived their names from the materials of which they were made, such as kugi-gata (nail form), hari-gata (needle form) and tantō-gata (knife form); some were named after an object of similar appearance, such as hoko-gata (spear form), matsuba-gata (pine-needle form); while others have names that are purely descriptive, such as kankyuto (piercing tool form), kunai-gata (utility tool form), or teppan (plate metal) and biao (pin).<ref name="mol" />

The bo-shuriken is thrown in a number of ways, such as overhead, underarm, sideways and rearwards, but in each case the throw involves the blade sliding out of the hand through the fingers in a smooth, controlled flight.

The major throwing methods are the jiki da-ho (direct-hit method), and the han-ten da-ho (turning-hit method). These two are technically different, in that the former does not allow the blade to spin before it hits the target, while the latter requires that the blade spin.

Other items such as hairpins, kogata (utility knife), and chopsticks were thrown in the same way as bo-shuriken, although they were not associated with any particular school of shurikenjutsu.

Hira shuriken/shakenEdit

Template:Nihongo3 or Template:Nihongo3 generally resemble the popular conception of shuriken.

They are constructed from thin, flat plates of metal derived from a variety of sources including hishi-gane (coins), kugi-nuki (carpentry tools), spools, and senban (nail removers).

They often have a hole in the center and possess a fairly thin blade sharpened mainly at the tip. The holes derive from their source in items that had holes—old coins, washers, and nail-removing tools.

This proved convenient for the shuriken user as the weapons could be strung on a string or dowel in the belt for transport, and the hole also had aerodynamic and weighting effects that aided the flight of the blade.<ref name="mol" />

There are a wide variety of forms of hira-shuriken, and they are now usually identified by the number of points the blades possess.

As with bo-shuriken, the various shapes of hira-shuriken were usually representative of a particular school (ryū) or region that preferred the use of such shapes, and it is therefore possible to identify the school by the type of blade used.<ref name="mol" />

UsageEdit

Shuriken functioned as supplementary weapons to the sword or to other weapons in a samurai's arsenal, although they often had an important tactical effect in battle.<ref name="bmbb">Template:Cite journal</ref><ref>Template:Cite book</ref><ref name=":3">Template:Cite book</ref>

Effective areasEdit

Shuriken targets were primarily the more exposed parts of the body: the eyes, face, hands, or feet.<ref name="bmbb" /><ref name=":2">Template:Cite book</ref>

Shuriken, despite low mass, were capable of dealing lethal blows at short ranges. In some cases, shuriken were capable of partially disemboweling targets.<ref>Template:Cite journal</ref>

Shuriken, especially hira-shuriken, were also used in novel ways—they could be embedded in the ground, injuring those who stepped on them (similar to a caltrop), wrapped in a fuse to be ignited and thrown to cause fire, or wrapped in a cloth soaked in poison and lit to cover an area with a cloud of poisonous smoke.<ref name="DD">Template:Cite book</ref>

They could also be used as a handheld weapon in close combat.<ref name="aabb">Template:Cite journal</ref>

There are reports of shuriken being coated with poison, intended either as a throwing weapon or to be left in a conspicuous place for a victim to pick up.<ref>Template:Cite journal</ref><ref name=":2" />

Other reports indicate that shuriken may have been buried in dirt or animal feces and allowed to harbor the bacterium clostridium tetani - if the point penetrated a victim deeply enough, the bacteria transferred into the wound could cause a then-incurable tetanus infection.<ref name=":2" />

ShurikenjutsuEdit

{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}} The art of wielding the shuriken is known as shurikenjutsu<ref name=":3" /> and was taught as a minor part of the martial-arts curriculum of many famous schools, such as Yagyū Shinkage-ryū, Tenshin Shōden Katori Shintō-ryū, Ittō-ryū, Kukishin-ryū, and Togakure-ryū.<ref name=":0" /><ref name=":1"> Template:Cite book</ref><ref name=":2" />

LegalityEdit

Modern commercially available shuriken, which are sold in Europe and North America, are often made of stainless steel.

However, in many countries and jurisdictions, they are illegal to possess or carry, such as in Belgium, the Netherlands, Canada,<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Germany,<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> and the United Kingdom (manufacture, sale, distribution and import).<ref>Template:Cite legislation UK</ref>

In the United States, they are prohibited in some states, such as California<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> and New York.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> In some cases they may be allowed, but may still be subject to specific local legislation. Owners may be required to possess a certificate for possession.

Various forms of Shuriken

Shuriken are simple weapons, but their historical value has increased.<ref name=":1" /><ref name=":2" />

Unlike the katana and other bladed weapons, antique shuriken are not often well preserved (although some are blackened in ash to prevent corrosion), largely due to their expendable nature.<ref name="cvg">Template:Cite book</ref>
