Bukijutsu (武器術; Literally meaning "Weapon Techniques") are techniques that entail the use of any handheld weapons in combat, whether the users be shinobi or samurai. Students of the Academy are taught the use of ninja weapons and tools like shuriken and kunai, learning how to throw and wield them through target practice.
Bukijutsu can be used in combination with taijutsu, ninjutsu, genjutsu, chakra flow, and even other weapons in order to achieve more devastating effects, such as the flail used in conjunction with the Infinite Armour, Kakashi Hatake's use of lightning-infused kunai, Asuma Sarutobi's use of wind-infused chakra knives for close-range fighting, and Danzō Shimura's wind-infused weapons. Kosuke Maruboshi's Leaf-Style Willow technique combines kenjutsu with Genjutsu. Orochimaru was also able to effectively combine the sight-impairing effects of the Bringer-of-Darkness Technique with shuriken to increase the likelihood of hitting his intended target. In addition to this, fūinjutsu are often used in conjunction with bukijutsu, as it provides a quick and easy means of transporting and using weapons. Because of this versatility, bukijutsu is employed in a vast array of ninja techniques.
Bukijutsu, in some form, is used by almost all shinobi. Tenten is a notable user of bukijutsu, as are the Gold and Silver Brothers, Kinkaku and Ginkaku, who were well known for their usage of the Treasured Tools of the Sage of the Six Paths. In the anime, Seimei, the Takumi Village founder, was also considered a very powerful bukijutsu user.
Types of Bukijutsu
Bōjutsu (棒術; Literally meaning "Staff Techniques") are techniques that involve the use of staffs for close-range fighting. The most notable user of such techniques was none other than the Third Hokage, Hiruzen Sarutobi. By using his technique to transform the Monkey King, Enma into a large staff, Hiruzen could use this art, which he was particularly skilled in, shown in his match against Orochimaru. With his staff techniques, he was even able to break the Wood Release of the First Hokage, Hashirama Senju.
Kayakujutsu (火薬術; Literally meaning "Gunpowder Techniques") are techniques that involve the use of explosives. A common variation of kayakujutsu is the usage of explosive tags. Often shinobi will attach these detonating tags to their weapons (usually a kunai) in order to make them deadlier. Hanzō, in particular, combines explosive tags into his Fire Release, creating a deadly technique which, even when avoided, can cause permanent damage, as it did to Nagato's legs.
Main article: Kenjutsu Kenjutsu (剣術; Literally meaning "Sword Technique") pertains to techniques that entail the use of swords, whether the users be shinobi, or samurai. Kenjutsu can be used in combination with taijutsu, ninjutsu, fūinjutsu, chakra flow and even genjutsu in order to achieve more devastating techniques. It is regarded as a branch of bukijutsu.
Main article: Shurikenjutsu Shurikenjutsu (手裏剣術; Literally meaning "sword hidden in the hand techniques") pertains to techniques that entail the throwing of shuriken, kunai, senbon or any other of a number of bladed, hand-held weapons. Shurikenjutsu can be used in combination with taijutsu, ninjutsu, and/or chakra flow in order to create more devastating techniques.
Kusarigamajutsu (鎖鎌術; Literally meaning "Kusarigama Technique") is a rarely used form of bukijutsu which uses the kusarigama. A notable user of this art is Hanzō, who took on the sword master, Mifune, with this technique. Hanzō was noted to use an unorthodox method, swinging the sickle with the chain rather than the weighted end, as is the most common and effective manner of using kusarigamajutsu. Hanzō also poisoned the sickle of his kusarigama, making it much more lethal to the point where even a single blow could decide a fight. Tenten has also displayed competence with this unique form of weapons technique and Jiga was also proficient with a kusarigama combining this skill with his Magnet Ninja Art.
Kyūjutsu (弓術; Literally meaning "Bow Technique"), another technique rarely seen in the ninja world, is one where the user will utilise a bow and arrow to attack targets from long-range. The most notable user of this art is Sasuke Uchiha, who was taught archery from a young age. In the present day, however, he mainly uses archery through his Susanoo technique. Archery seems to require a great deal of precision and aim. Kidōmaru, while using his Cursed Seal Level 2, uses his Spider War Bow: Terrible Split, a type of kyūjutsu. He was skilled enough with it to leave Neji Hyūga, a master of the Byakugan, near-death.
Outside of the traditional techniques of bukijutsu, shinobi have come up with other methods to employ ninja tools. Might Guy, for example is extraordinarily skilful with his Sōshūga, being able to effectively employ it against Obito Uchiha during the Fourth Shinobi World War. His use of this weapon is particularly unique in that he could use them to fight Kisame who was using Samehada, a sword. Other shinobi, such as Kinkaku, Ginkaku, and the Seven Ninja Swordsman of the Mist, base their fighting style around the utilisation of their weapon's special abilities. For example, Zabuza Momochi's Kubikiribōchō can regenerate by using the blood of those it has slain. Therefore, Zabuza makes every effort to cut his foes and draw blood.
Madara Uchiha also utilised unique forms of bukijutsu, employing a kama during his fight with Hashirama Senju, and both he and Obito Uchiha can utilise gunbai in close-range combat. Madara himself incorporates his gunbai with his ninjutsu techniques while Obito, on the other hand, uses it in an unorthodox fashion as a flail and a defence mechanism, using it to block Naruto Uzumaki's Rasengan and Guy's Sōshūga. Obito will also use shurikenjutsu combined with his Kamui technique, allowing him to eject several large shuriken, without warning, to defeat his foes. He has also been shown using shuriken as melee weapons, which is unique to him.
Bukijutsu is also employed in certain kekkei genkai. Toroi, of Kumogakure, would use his Magnet Release kekkei genkai to magnetise his large, specialised shuriken, causing the struck target to become magnetised. One hit to the body will cause a magnetic field within the said body, making it an easy target for any further magnetised weapons to be drawn to it. However, each time the magnetism is transferred, it weakens. Additionally, the Mangekyō Sharingan technique of the Uchiha Clan, Susanoo, will manifest unique spirit weapons when mature enough. Bukijutsu is also employed in Minato Namikaze's Space–Time Ninjutsu, making use of specialised kunai to allow him to move around using the technique, or to change the course of an opponent's technique.
In the anime, Seimei, the founder of the Takumi Village, created four unique weapons which, when used together, were considered by the village to be the "Ultimate Weapon". These were the Garian Sword, the Infinite Armour, the Weaknessless Soaring Shortswords, and an unnamed longsword. When used together, Seimei was able to fight on par with Gaara, who was the jinchūriki of Shukaku at the time.
Main article: Puppet Puppets (傀儡, Kugutsu) are used as weapons by puppeteers. They are most often humanoid-looking creations, but depending on the creator, can resemble anything. They are fashioned in a manner that uses every part as a weapon, giving the puppeteer a myriad of ways to manipulate it. Puppets are long-ranged type weapons that can be used offensively, defensively or for supplementary reasons, and are controlled via Chakra Threads. Because of their design, the weak point of any puppet is its joints. There are two types of puppets: ones made from material such as wood, and Human Puppets. Famed puppeteer Sasori of the Red Sand was the inventor of human puppets and also created a puppet which he wore like armour, bypassing the usual disadvantage that puppeteers had of being weak in close-ranged combat. Puppets are often sealed within scrolls using fūinjutsu, for ease of transport.
Main article: Manipulated Tools
Tenten's fighting style is completely reliant on her own unique applications of bukijutsu. Because of her skill with fūinjutsu, she seals her weapons into an assortment of scrolls, allowing her to perform various techniques unique to herself. For example, she can toss her larger scrolls into the air, causing the tools sealed within to rain down on her target. In the anime, her Twin Rising Dragons technique allows her to assault her foe with an endless barrage of ninja tools. She can also use this style of fighting as a defence mechanism should the situation call for it.
- The Kōga-ryū, a historical school of ninjutsu located in the region of Kōka, taught Kakushi bukijutsu (隠し武器術; Literally meaning "Hidden Weapons Techniques"), with several sub-groups, such as kenjutsu (sword techniques), bōjutsu (long staff techniques), and kyūjutsu (archery).
- Though he is not a noted bukijutsu user, in the OVA of the fight between Madara Uchiha and Hashirama Senju, on the game Naruto Shippūden: Ultimate Ninja Storm Generations, Hashirama can be seen summoning a vast amount of swords and other ninja tools from one of his giant scrolls.
