Ninja Juhakkei were often studied along with the Bugei Juhappen (the 18 samurai fighting art skills).
Though some techniques were used in the same way by both samurai and ninja, others were utilized differently by the two warriors. The 18 disciplines are as follows:

• Seishin Teki Kyoyo - Spiritual Refinement
  The Togakure Ryu Ninja worked at developing a deep and accurate understanding of himself, his personal power, his strengths and weaknesses, and his influence on the playing out of life. The Ninja had to be very clear about his intentions, his commitments and his personal motivations in life. Personality traits could often mean the difference between life and death in his line of work. Exercises in mental endurance, ways of looking at things, were taught to the ninja along with his physical skills. By evolving into a mystics understanding of the universal process, the historical Togakure Ryu Ninja would became a warrior philosopher. His engagements in combat were then motivated by love or reverence and not by mere thrill of violent danger or need for money.
  
  
• Taijutsu - Unarmed Combat
  Skills of Dakentaijutsu or striking, kicking and blocking, Jutaijutsu or grappling, Jime (chokes) and escaping the holds of others, Taihenjutsu or silent movement, rolling, leaping and tumbling (Kurowaza) assisted the Togakure Ryu Ninja in life threatening defensive situations.
  
  
• Kenjutsu / Bikenjutsu - Sword Techniques
  The ninja’s sword (shinobigatana) had a short straight single edged blade and was considered to be his primary fighting tool. Two distinct sword skills were required by the ninja, “Fast Draw” techniques centred around drawing the sword and cutting as a simultaneous defensive or offensive action. “Fencing” skills used the drawn sword in technique clashes with armed attackers.
  
  
• Rokkushakubojutsu / Bojutsu - Stick Fighting
  
  The Japanese stick fighting art, practiced by Samurai and Peasants alike, was also a strong skill of the ninja. Togakure Ryu Ninja were taught to use the Bo (long staff – 6ft), Jo (4ft staff) and Hanbo (half staff – 3ft) as well as sticks and clubs of varying lengths. Specially constructed Shinobi-Zue or Ninja canes were designed to look like normal walking sticks, but concealed blades, chains, or darts that could be used against the enemy.
  
  
• Shurikenjutsu - Throwing Weapon Techniques
  
  Throwing blades were carried in concealed pockets and used as harassing weapons. The Togakure Ryu used a special four pointed throwing star called a Senban Shuriken, which was constructed from a thin steel plate. The blade was thrown with a flat spinning motion and hits its target with a sawing effect. Bo Shuriken or straight shaft darts and spikes were also constructed for throwing. Throwing stars in general are called Hira Shuriken.
  
  
• Sojutsu - Spear Tecniques
  
  Togakure Ryu Ninja were taught to use standard Japanese spears and lances as middle range fighting weapons. Spears and Lances were used for stabbing and piercing attacks, and rarely ever thrown in normal combat. The Togakure Ryu also used a unique spear weapon called a Kama Yari or “Sickle Lance”, which consisted of a spear blade with a hook at the base. The total length of the weapon was over nine feet. The lance point could be used to lunge and stab, and the hook point could be used to snag and pull the opponent or his weapon.
  
  
• Naginatajutsu / Besentojutsu - Halberd Techniques
  
  Virtually a short sword blade mounted on a Rokushakubo, the Japanese Naginata was used for cutting and slashing attacks against adversaries at medium range. Togakure Ryu Ninja were also proficient in the use of the Bisento, A huge heavy bladed version of the Naginata. Based on a Chinese weapon the broad bladed weapon was heavy enough to knock down attackers, smash through armour and ground the horses of mounted Samurai.
  
  
• Kusarigamajutsu - Sickle & Chain Techniques
  
  The Japanese Kusarigama was adopted into the arsenal of the Togakure Ryu Ninja. A chain, six to nine feet in length with a Fundo (weight) attached at one end, was attached to the handle of a Kama (sickle) a traditional grain cutting tool. The chain could be used to block or ensnare the enemies weapon and the blade then used to finish off the attacker.
  
  
• Kyogetsu Shoge - Over The Fields And Plains
  A weapon similar to the Kusarigama, It was favoured by the Togakure Ryu Ninja. The Kyogetsu Shoge is commonly thought of as the predecessor to the Kusarigama. The weapon consisted of a straight blade with a secondary forward facing hook blade protruding from the hilt, attached to a fifteen foot resilient cord usually made from a woman’s or horses hair. A large steel ring was attached to the free end of the cord with the other end attaching to the Kashira/Pommel of the blade.
  
  
• Kayakujutsu - Pyrotechnics
  
  Togakure Ryu Ninja were experts in the placement, timing and rigging of explosive devices for demolition and distraction predominantly utilizing fire and smoke. In later years, the use of black powder or Bakuyaku and other explosives were supplemented with knowledge of firearms and their strategic applications. Kayakujutsu was generally taught in three stages Katon No Jutsu – the use of fire smoke and heat for infiltration, evasion and deception, Kayakujutsu – The use of gunpowder, firearms and explosives, Shinobi Kaki – Fire Tools
  
  
• Hensojutsu - Disguise And Impersonation
  
  Essential to the ninja’s espionage work was his ability to assume false identities and move undetected through his area of operation. More than merely putting on a costume, Ninjutsu’s disguise system involves thoroughly impersonating the character adopted. Personality traits, areas of knowledge and body dynamics of the identity assumed were ingrained in the ninja’s way of thinking and reacting. He or she literally became the new personality, whether taking the role of a monk, craftsman or wandering entertainer. This art of assuming alternate identities is called Shi Chi Ho De (The Art of Seven Disguises)
  
  
• Shinobi Iri - Stealth And Entering Methods
  
  The ninja’s techniques of silent movement, breaking and entering, and gaining access to inaccessible areas became legendary in feudal Japan. Togakure Ryu Ninja learned special walking and running methods for covering long distances, passing over floors silently and for staying in the shadows while moving, in order to facilitate entry and escape.
  
  
• Bajutsu - Horsemanship
  
  Togakure Ryu Ninja were taught to be proficient on horseback, both in riding and mounted combat skills.
  
  
• Sui Ren - Water Training
  
  Stealth swimming, silent movement through water, methods of using special boats and floats to cross over water, and underwater combat techniques were taught to Togakure Ryu Ninja. Also training and fighting in icy conditions, most often performed by practicing Taijutsu wearing Geta (wooden sandals) on ice.
  
  
• Bo Ryaku - Strategy And Tactics
  
  Unconventional tactics of deception and battle, political plots and advantageous timing for use of current events were used by Togakure Ryu Ninja. By employing or influencing seemingly outside forces to bring the enemy around to doing what the Ninja wanted him to do, Ninja were able to work their will without drawing undue attention to themselves. This is an extensive area of study which cannot be summarized into a small caption
  
  
• CHo Ho - Espionage
  
  Methods of successful espionage were perfected. This included ways of locating and recruiting spies and served as a guide for using espionage agents as efficiently as possible.
  
  
• Intonjutsu - Escape And Concealment
  
  Togakure Ryu Ninja were experienced masters in the ways of using nature to cover their exit, allowing them to “disappear” at will. The Goton Po five elements of escape were based on a working familiarity with the creative use of Earth (Chi), Water (Sui), Fire (Ka), Metal (Kin) and Wood (Moku) aspects of nature and the environment.
  
  
• Ten Mon - Meteorology
  
  Forecasting and taking advantage of the weather and seasonal phenomena was an important part of any battle consideration. Ninja were trained to observe all the subtle signals from the environment in order to predict weather conditions.
  
  
• Chi Mon - Geography
  
  Knowing and successfully using the features of the terrain were crucial skills in the historical art of Ninjutsu. High and Low points, Undulated Terrain, Horizons, Cover, Etc.
