KatanaA katana is a Japanese sword characterized by a curved, single-edged blade with a circular or squared guard and long grip to accommodate two hands. Developed later than the tachi, it was used by samurai in feudal Japan and worn with the edge facing upward. Since the Muromachi period, many old tachi were cut from the root and shortened, and the blade at the root was crushed and converted into katana. The specific term for katana in Japan is uchigatana (打刀) and the term katana (刀) often refers to single-edged swords from around the world.
NinjaA ninja (忍者; ɲiꜜɲdʑa) or shinobi (忍び; ɕinobi) was a covert agent, mercenary, or guerrilla warfare expert in feudal Japan. The functions of a ninja included siege and infiltration, ambush, reconnaissance, espionage, deception, and later bodyguarding and their fighting skills in martial arts, including ninjutsu. Their covert methods of waging irregular warfare were deemed dishonorable and beneath the honor of the samurai.
Iaido, abbreviated iai, is a Japanese martial art that emphasizes being aware and capable of quickly drawing the sword and responding to sudden attacks. Iaido consists of four main components: the smooth, controlled movements of drawing the sword from its scabbard (or saya), striking or cutting an opponent, shaking blood from the blade, and replacing the sword in the scabbard. While beginning practitioners of iaido may start learning with a wooden sword (bokken) depending on the teaching style of a particular instructor, most of the practitioners use a blunt-edged sword called an iaitō or mogitō.
Japanese swordA Japanese sword is one of several types of traditionally made swords from Japan. Bronze swords were made as early as the Yayoi period (1000 BC – 300 AD), though most people generally refer to the curved blades made from the Heian period (794 – 1185) to the present day when speaking of "Japanese swords". There are many types of Japanese swords that differ by size, shape, field of application and method of manufacture. Some of the more commonly known types of Japanese swords are the uchigatana, tachi, odachi, wakizashi, and tantō.
TantōA 短刀 is one of the traditionally made Japanese swords (nihonto) that were worn by the samurai class of feudal Japan. The tantō dates to the Heian period, when it was mainly used as a weapon but evolved in design over the years to become more ornate. Tantō were used in traditional martial arts (tantojutsu). The term has seen a resurgence in the West since the 1980s as a point style of modern tactical knives, designed for piercing or stabbing. The tantō is a single or double edged dagger with a length between (1 Japanese shaku).
Japanese martial artsJapanese martial arts refers to the variety of martial arts native to the country of Japan. At least three Japanese terms (budō, bujutsu, and bugei) are used interchangeably with the English phrase Japanese martial arts. The usage of the term budō (武道) to mean martial arts is a modern one: historically the term meant a way of life encompassing physical, spiritual and moral dimensions with a focus on self-improvement, fulfillment or personal growth. The terms bujutsu (武術) and bugei (武芸) have different meanings from budō, at least historically speaking.
SwordA sword is an edged, bladed weapon intended for manual cutting or thrusting. Its blade, longer than a knife or dagger, is attached to a hilt and can be straight or curved. A thrusting sword tends to have a straighter blade with a pointed tip. A slashing sword is more likely to be curved and to have a sharpened cutting edge on one or both sides of the blade. Many swords are designed for both thrusting and slashing. The precise definition of a sword varies by historical epoch and geographic region.
SamuraiSamurai were the hereditary military nobility and officer caste of medieval and early-modern Japan from the late 12th century until their abolition in the late 1870s during the Meiji era. They were the well-paid retainers of the daimyo, the great feudal landholders. They had high prestige and special privileges. Following the passing of a law in 1629, samurai on official duty were required to practice daishō (wear two swords). Samurai were granted kiri-sute gomen: the right to kill anyone of a lower class in certain situations.
