Judo ( Japanese : 柔道 , Hepburn : Jūdō , lit.   ' gentle way ' ) is an unarmed modern Japanese martial art , combat sport , Olympic sport (since 1964), and the most prominent form of jacket wrestling competed internationally. Judo was created in 1882 by Kanō Jigorō ( 嘉納 治五郎 ) as an eclectic martial art, distinguishing itself from its predecessors (primarily Tenjin Shinyo-ryu jujutsu and Kitō-ryū jujutsu) due to an emphasis on " randori " ( 乱取り , lit. 'free sparring') instead of kata ( 形 , kata , pre-arranged forms) alongside its removal of striking and weapon training elements. Judo rose to prominence for its dominance over established jujutsu schools in tournaments hosted by the Tokyo Metropolitan Police Department (警視庁武術大会, Keishicho Bujutsu Taikai ), resulting in its adoption as the department's primary martial art. A judo practitioner is called a "judoka" ( 柔道家 , jūdōka , lit.   ' judo performer ' ) , and the judo uniform is called "judogi" ( 柔道着 , jūdōgi , lit.   ' judo attire ' ) .

62-510: The objective of competitive judo is to throw an opponent, immobilize them with a pin , or force an opponent to submit with a joint lock or a choke . While strikes and use of weapons are included in some pre-arranged forms (kata), they are not frequently trained and are illegal in judo competition or free practice. Judo's international governing body is the International Judo Federation , and competitors compete in

124-419: A Waza is known as tori ( 取り , literally "taker") and the person to whom it is performed is known as uke ( 受け , "receiver") . Nage-waza include all techniques in which tori attempts to throw or trip uke , usually with the aim of placing uke on their back. Each technique has three distinct stages: Nage-waza are typically drilled by the use of uchi-komi ( 内込 ) , repeated turning-in, taking

186-482: A throw is a grappling technique that involves off-balancing or lifting an opponent, and throwing them to the ground, in Japanese martial arts referred to as nage-waza , 投げ技, "throwing technique". Throws are a subset of takedown (grappling) . Certain throwing techniques called sacrifice throws ( sutemi-waza , 捨身技, "sacrifice technique") involve putting oneself in a potentially disadvantageous position, such as on

248-433: A back arch). Variations of the suplex are common in most forms of wrestling and sometimes used in mixed martial arts competition. In Judo, the ura-nage throw is a version of the suplex, but it is classified as a sacrifice throw. Some of the more common throwing techniques are listed below. This is not an exhaustive list and the techniques may be referred to by other names in different styles. An English translation and

310-630: A common Japanese equivalent are given. ( Wayback Machine copy) Randori Randori ( 乱取り ) is a term used in Japanese martial arts to describe free-style practice (sparring). The term denotes an exercise in 取り tori , applying technique to a random ( 乱 ran ) succession of uke attacks. The actual connotation of randori depends on the martial art it is used in. In judo , jujutsu , and Shodokan aikido , among others, it most often refers to one-on-one sparring where partners attempt to resist and counter each other's techniques. In other styles of aikido , in particular Aikikai , it refers to

372-461: A common origin with the Chinese concept of tao . Thus Kano renamed it Jūdō ( 柔道 , judo) . There are three basic categories of waza ( 技 , techniques) in judo: nage-waza ( 投げ技 , throwing techniques) , katame-waza ( 固技 , grappling techniques) and atemi-waza ( 当て身技 , striking techniques) . Judo is mostly known for nage-waza and katame-waza . Judo practitioners typically devote

434-584: A core sport in the 22nd edition of the Commonwealth Games, in Birmingham and also the 23rd edition of the Commonwealth Games in Glasgow. Penalties may be given for: passivity or preventing progress in the match; for safety infringements for example by using prohibited techniques, or for behavior that is deemed to be against the spirit of judo. Fighting must be stopped if a participant is outside

496-431: A different name principally because my objectives were much wider than jujitsu. Kano believed that " jūjutsu " was insufficient to describe his art: although jutsu ( 術 ) means "art" or "means", it implies a method consisting of a collection of physical techniques. Accordingly, he changed the second character to dō ( 道 ) , meaning "way", "road" or "path", which implies a more philosophical context than jutsu and has

558-419: A form of practice in which a designated aikidoka defends against multiple attackers in quick succession without knowing how they will attack or in what order. The term is used in aikido, judo, and Brazilian jiu-jitsu dojos outside Japan. In Japan, this form of practice is called taninzu-gake ( 多人数掛け ) , which literally means multiple attackers. The term was described by Jigoro Kano, the founder of judo, in

620-585: A greater focus on nage-waza ( 投げ技 , throwing techniques) . In February 1882, Kano founded a school and dōjō at the Eisho-ji ( 永昌寺 ) , a Buddhist temple in what was then the Shitaya ward of Tokyo (now the Higashi Ueno district of Taitō ward). Iikubo, Kano's Kitō-ryū instructor, attended the dōjō three days a week to help teach and, although two years would pass before the temple would be called by

682-524: A jujutsu concept, had a wider philosophical application. Coupled with the Confucianist -influenced jita kyōei , the wider application shaped the development of judo from a bujutsu ( 武術 , martial art) to a budō ( 武道 , martial way) . Kano rejected techniques that did not conform to these principles and emphasized the importance of efficiency in the execution of techniques. He was convinced that practice of jujutsu while conforming to these ideals

744-523: A jujutsu teacher who was willing to take him on met with little success. Jujutsu had become unfashionable in an increasingly westernized Japan. Many of those who had once taught the art had been forced out of teaching or become so disillusioned with it that they had simply given up. Nakai Umenari, an acquaintance of Kanō's father and a former soldier, agreed to show him kata , but not to teach him. The caretaker of Jirosaku's second house, Katagiri Ryuji, also knew jujutsu, but would not teach it as he believed it

806-581: A lifting motion from the hips; and ashi-waza ( 足技 , foot and leg techniques) , throws in which tori predominantly utilises their legs. Katame-waza is further categorised into osaekomi-waza ( 抑込技 , holding techniques) , in which tori traps and pins uke on their back on the floor; shime-waza ( 絞技 , strangulation techniques) , in which tori attempts to force a submission by choking or strangling uke ; and kansetsu-waza ( 関節技 , joint techniques) , in which tori attempts to submit uke by painful manipulation of their joints. A related concept

868-482: A match with yuko scores now included within waza-ari. Ippon is scored in ne-waza for pinning an opponent on his back with a recognised osaekomi-waza for 20 seconds or by forcing a submission through shime-waza or kansetsu-waza . A submission is signalled by tapping the mat or the opponent at least twice with the hand or foot, or by saying maitta ( まいった , I surrender) . A pin lasting for less than 20 seconds, but more than 10 seconds scores waza-ari (formerly waza-ari

930-437: A more powerful opponent will result in your defeat, whilst adjusting to and evading your opponent's attack will cause him to lose his balance, his power will be reduced, and you will defeat him. This can apply whatever the relative values of power, thus making it possible for weaker opponents to beat significantly stronger ones. This is the theory of ju yoku go o seisu . Kano realised that seiryoku zen'yō , initially conceived as

992-508: A number of derivative martial arts around the world, such as Brazilian jiu-jitsu , Krav Maga , sambo , and ARB . Judo also influenced the formation of other combat styles such as close-quarters combat (CQC), mixed martial arts (MMA), shoot wrestling and submission wrestling . The early history of judo is inseparable from its founder, Japanese polymath and educator Kanō Jigorō ( 嘉納 治五郎 , Jigoro Kano, 1860–1938) , born Shinnosuke Jigorō ( 新之助 治五郎 , Jigorō Shinnosuke) . Kano

1054-536: A number of these, Kano was referred to Fukuda Hachinosuke ( c.  1828 –1880), a teacher of the Tenjin Shin'yō-ryū of jujutsu, who had a small nine mat dōjō where he taught five students. Fukuda is said to have emphasized technique over formal exercise, sowing the seeds of Kano's emphasis on randori ( 乱取り , randori , free practice) in judo. On Fukuda's death in 1880, Kano, who had become his keenest and most able student in both randori and kata ,

1116-413: A portion of each practice session to ukemi ( 受け身 , break-falls) , in order that nage-waza can be practiced without significant risk of injury. Several distinct types of ukemi exist, including ushiro ukemi ( 後ろ受身 , rear breakfalls) ; yoko ukemi ( 横受け身 , side breakfalls) ; mae ukemi ( 前受け身 , front breakfalls) ; and zenpo kaiten ukemi ( 前方回転受身 , rolling breakfalls) The person who performs

1178-659: A retrograde form as ju-jitsu was before the Kodokan was founded. Judo should be free as art and science from any external influences, political, national, racial, and financial or any other organized interest. And all things connected with it should be directed to its ultimate object, the "Benefit of Humanity". Human sacrifice is a matter of ancient history. At the 57th general session of the International Olympic Committee , held in Rome on 22 August 1960,

1240-724: A separate style of Judo, Kosen judo is a competition rules set of Kodokan judo that was popularized in the early 20th century for use in Japanese Special High Schools Championships held at Kyoto Imperial University. The word "Kosen" is an acronym of Koto Senmon Gakko ( 高等専門学校 , literally "Higher Professional School") . Currently, competitions are organized between Japan's seven former Imperial Universities and referred to as Nanatei Judo ( ja:七帝柔道 , literally "Seven Emperors Judo"). Kosen judo's focus on newaza has drawn comparisons with Brazilian jiu-jitsu . Throw (grappling) In martial arts ,

1302-546: A speech at the 1932 Los Angeles Olympic Games: "Randori, meaning "free exercise", is practiced under conditions of actual contest. It includes throwing, choking, holding the opponent down, and bending or twisting of the arms. The two combatants may use whatever methods they like provided they do not hurt each other and obey the rules of judo concerning etiquette, which are essential to its proper working." There are 2 types of randori. Most commonly, one or more attackers rush toward tori and try to grab both elbows. The tori's goal

1364-508: A traditional Japanese sport has been included in the Olympic competition. Finally, judo was first contested as an Olympic sport for men in the 1964 Games in Tokyo . The Olympic Committee initially dropped judo for the 1968 Olympics, meeting protests. Dutchman Anton Geesink won the first Olympic gold medal in the open division of judo by defeating Akio Kaminaga of Japan. The women's event

1426-514: A variety of forms of practice, and the intensity at which it is carried out varies depending on intent and the level of expertise of the participants. At one extreme, is a compliant style of randori, known as Yakusoku geiko ( 約束稽古 , prearranged practice) , in which neither participant offers resistance to their partner's attempts to throw. A related concept is that of Sute geiko ( 捨稽古 , throw-away practice) , in which an experienced judoka allows himself to be thrown by his less-experienced partner. At

1488-402: A waza-ari ( 技あり ) . Two scores of waza-ari equal an ippon waza-ari awasete ippon ( 技あり合わせて一本 ,  ) . This rule was cancelled in 2017, but it was resumed in 2018. Formerly, a throw that places the opponent onto his side scores a yuko ( 有効 ) . In 2017, the International Judo Federation announced changes in evaluation of points. There will only be ippon and waza-ari scores given during

1550-481: Is a means for personal cultural attainment. Only one of the forms of judo training, so-called randori or free practice can be classed as a form of sport. Certainly, to some extent, the same may be said of boxing and fencing, but today they are practiced and conducted as sports. Then the Olympic Games are so strongly flavored with nationalism that it is possible to be influenced by it and to develop "Contest Judo",

1612-518: Is conventional for the Japanese to name their throws in this manner, and many western martial art dojos have given English names to the throws feeling that it is easier for English speaking students to remember the names of throws if they can associate the throws by the descriptive nature of the throw name. In Judo, throws are divided into six categories—hand techniques, leg techniques, hip techniques, shoulder techniques, as well as sacrifice throws to

1674-528: Is placed upon both the uke (receiver) and the tori (thrower). A hip throw involves using the thrower's hip as a pivot point, by placing the hip in a lower position than an opponent's center of gravity. There are several types of hip throws such as O Goshi , which is often taught first to novices. Hip throws in Judo are called Koshi Waza, and in Aikido or Sumo they are called koshinage. Pickups involve lifting

1736-580: Is that of ne-waza ( 寝技 , prone techniques) , in which waza are applied from a non-standing position. In competitive judo, Kansetsu-waza is currently limited to elbow joint manipulation. Manipulation and locking of other joints can be found in various kata, such as Katame-no-kata and Kodokan goshin jutsu . Atemi-waza are techniques in which tori disables uke with a strike to a vital point. Atemi-waza are not permitted outside of kata . Judo pedagogy emphasizes randori ( 乱取り , literally "taking chaos", but meaning "free practice") . This term covers

1798-440: Is the most popular and well-known style of judo, but is not the only one. The terms judo and jujutsu were quite interchangeable in the early years, so some of these forms of judo are still known as jujutsu or jiu-jitsu either for that reason, or simply to differentiate them from mainstream judo. From Kano's original style of judo, several related forms have evolved—some now widely considered to be distinct arts: Commonly described as

1860-415: Is to perform quick tai sabaki and avoid hurting the attackers as much as possible. Therefore, the tori does not punch, but rather tries to avoid the attacks or to throw the attackers. In some aikido styles, the attack is free, and so are the techniques applied, as long as they follow the principles of aikido. Although in karate the word kumite is usually reserved for sparring, some schools also employ

1922-466: The IOC members formally decided to include Judo among the events to be contested at the Olympic Games. The proposal, which was placed before the session by the Japanese delegation, was welcomed by all participants. The few who opposed had nothing against Judo itself but against increasing the number of Olympic events as a whole. There were only two dissenting votes in the final poll. For the first time in history

1984-631: The Kodokan today: In addition, there are a number of commonly practiced kata that are not recognised by the Kodokan. Some of the more common kata include: Contest ( 試合 , shiai ) is a vitally important aspect of judo. In 1899, Kano was asked to chair a committee of the Dai Nippon Butoku Kai to draw up the first formal set of contest rules for jujutsu. These rules were intended to cover contests between different various traditional schools of jujutsu as well as practitioners of Kodokan judo. Contests were 15 minutes long and were judged on

2046-602: The age of seven, he studied English, shodō ( 書道 , Japanese calligraphy ) and the Four Confucian Texts ( 四書 , Shisho ) under a number of tutors. When he was fourteen, Kano began boarding at an English-medium school, Ikuei-Gijuku in Shiba, Tokyo . The culture of bullying endemic at this school was the catalyst that caused Kano to seek out a Jūjutsu ( 柔術 , Jujutsu ) dōjō ( 道場 , dōjō , training place) at which to train. Early attempts to find

2108-406: The basis of nage waza and katame waza , excluding atemi waza . Wins were by two ippons, awarded in every four-main different path of winning alternatives, by "Throwing", where the opponent's back strikes flat onto the mat with sufficient force, by "Pinning" them on their back for a "sufficient" amount of time, or by "Submission", which could be achieved via Shime-waza or Kansetsu-waza , in which

2170-410: The designated area on the mat. There are currently seven weight divisions , subject to change by governing bodies, and may be modified based on the age of the competitors: A throw that places the opponent on their back with impetus and control scores an ippon ( 一本 ) , winning the contest. A lesser throw, where the opponent is thrown onto his back, but with insufficient force to merit an ippon, scores

2232-502: The difference is that a reap is one smooth move, like that of a scythe , whereas a hook is pulling the opponents leg up first, and then swinging it away. Common leg trips are hooking variations of Ouchi Gari and Osoto Gari along with Kosoto Gake , referred to as inside and outside trips in Western wrestling. Sacrifice throws require the thrower to move into a potentially disadvantageous position in order to be executed, such as falling to

2294-573: The exception of elements of the Seiryoku-Zen'yō Kokumin-Taiiku , they are all practised with a partner. Their purposes include illustrating the basic principles of judo, demonstrating the correct execution of a technique, teaching the philosophical tenets upon which judo is based, allowing for the practice of techniques that are not allowed in randori, and to preserve ancient techniques that are historically important but are no longer used in contemporary judo. There are ten kata that are recognized by

2356-457: The first contestant to achieve any score wins. If there is no score during this period, then the winner is decided by Hantei ( 判定 ) , the majority opinion of the referee and the two corner judges. There have been changes to the scoring. In January 2013, the Hantei was removed and the "Golden Score" no longer has a time limit. The match would continue until a judoka scored through a technique or if

2418-477: The following year, the pair were granted shodan ( 初段 , first rank) grades, the first that had been awarded in any martial art. Central to Kano's vision for judo were the principles of seiryoku zen'yō ( 精力善用 , maximum efficiency, minimum effort) and jita kyōei ( 自他共栄 , mutual welfare and benefit) . He illustrated the application of seiryoku zen'yō with the concept of jū yoku gō o seisu ( 柔能く剛を制す - 柔能剛制 , softness controls hardness) : In short, resisting

2480-605: The ground, in order to execute a throw. There are several major types of throw, among Asian martial arts , Judo has the most developed throwing techniques and throws are considered its specialty. Most throws are named by describing the circumvention point of the throw (e.g., hip throw, shoulder throw, wrist throw etc.), or the nature of effect of the throw on the opponent (e.g., heaven and earth throw, valley drop, body drop) with variations being given descriptive names. The names used here are attributed to Jujutsu throws (and hence judo/ Aikido throws) are descriptions in Japanese. It

2542-402: The ground. The momentum of the falling body adds power to the throw and requires comparatively little strength, compared to the effect. In Judo (as well as in other martial arts), these throws are called sutemi waza and are further divided into rear (ma sutemi waza) and side (yoko sutemi waza) throws. In Judo, these throws are limited to a specific grade and higher due to the element of danger that

2604-430: The international IJF professional circuit. Judo's philosophy revolves around two primary principles: "Seiryoku-Zenyo" ( 精力善用 , lit.   ' good use of energy ' ) and "Jita-Kyoei" ( 自他共栄 , lit.   ' mutual welfare and benefit ' ) . The philosophy and subsequent pedagogy developed for judo became the model for other modern Japanese martial arts that developed from Ko-ryū . Judo has also spawned

2666-510: The name Kōdōkan ( 講道館 , Kodokan , "place for expounding the way") , and Kano had not yet received his Menkyo ( 免許 , certificate of mastery) in Kitō-ryū , this is now regarded as the Kodokan founding. The Eisho-ji dōjō was originally shoin . It was a relatively small affair, consisting of a 12 jo (214 sq ft) training area. Kano took in resident and non-resident students, the first two being Tomita Tsunejirō and Shiro Saigo . In August,

2728-427: The opponent is penalised (Hansoku-make). Two types of penalties may be awarded. A shido (指導 – literally "guidance") is awarded for minor rule infringements. A shido can also be awarded for a prolonged period of non-aggression. Recent rule changes allow for the first shidos to result in only warnings. If there is a tie, then and only then, will the number of shidos (if less than three) be used to determine

2790-420: The opponent off the ground and then bringing them down again. Common pick-ups are lifting variations of the double leg takedown , Judo's Te Guruma or sukui nage (both classified as hand throws Ganseki otoshi ) and the suplex from wrestling, in which the attacker lifts their opponents body vertically and throws the opponent over their own center of gravity while executing a back fall (usually accompanied by

2852-456: The opponent to fall over. Common leg reaps are judo's Ouchi Gari , Kouchi Gari , Osoto Gari , and Kosoto Gari . There are similar techniques in wrestling, including the inside and outside trips. Somewhat similar to leg reaps involve a hooking or lifting action with the attacking leg instead of a reaping action. The border between the two types of throw can be unclear, and many throws will exhibit characteristics of both reaps and trips, however,

2914-575: The opponent was forced to give himself or herself up or summon a referee's or corner-judge's stoppage. Finger, toe and ankle locks were prohibited. In 1900, these rules were adopted by the Kodokan with amendments made to prohibit all joint locks for kyu grades and added wrist locks to the prohibited kansetsu-waza for dan grades. It was also stated that the ratio of tachi-waza to ne-waza should be between 70% and 80% for kyu grades and between 60% and 70% for dan grades. In 1916, additional rulings were brought in to further limit kansetsu waza with

2976-415: The opposite extreme from yakusoku geiko is the hard style of randori that seeks to emulate the style of judo seen in competition. While hard randori is the cornerstone of judo, over-emphasis of the competitive aspect is seen as undesirable by traditionalists if the intent of the randori is to "win" rather than to learn. Kata ( 形 , kata, forms) are pre-arranged patterns of techniques and in judo, with

3038-508: The prohibition of ashi garami and neck locks, as well as do jime . These were further added to in 1925. Jigoro Kano for a long time wished to see judo as an Olympic discipline . The first time judo was seen in the Olympic Games was in an informal demonstration hosted by Kano at the 1932 Games . However, Kano was ambivalent about judo's potential inclusion as an Olympic sport: I have been asked by people of various sections as to

3100-506: The rear and side. A shoulder throw involves throwing an opponent over the shoulder. A shoulder throw which lifts the opponent from the ground is in Japanese referred to as seoi-nage (背負い投げ, "Back Throw"), while a throw which involves upsetting the opponent’s balance and pulling the opponent over the shoulder is referred to as seoi-otoshi (背負落とし, "Back Drop"). Seoi-nage is one of the most used throws in judo competition. One study indicated that approximately 56% of judokas implemented

3162-421: The technique. A common shoulder throw is judo's ippon seoinage ("Single-Handed Back Throw") or the similar flying mare in wrestling . In a leg reap , the attacker uses one of their legs to reap one or both of their opponent's legs off the ground. Generally the opponent's weight is placed on the leg that is reaped away. This coupled with the attacker controlling the opponent's body with their hands causes

3224-490: The term randori with regard to "mock-combat" in which both karateka move with speed, parrying and attacking with all four limbs (including knees and elbows). In these schools, the distinction between randori and kumite is that in randori, the action is uninterrupted when a successful technique is applied. (Also known as ju kumite or soft sparring.) Randori is also practiced in Bujinkan ninjutsu and usually represented to

3286-551: The throw up to the point of kake . Traditionally, nage-waza are further categorised into tachi-waza ( 立ち技 , standing techniques) , throws that are performed with tori maintaining an upright position, and sutemi-waza ( 捨身技 , sacrifice techniques) , throws in which tori sacrifices his upright position in order to throw uke . Tachi-waza are further subdivided into te-waza ( 手技 , hand techniques) , in which tori predominantly uses their arms to throw uke ; koshi-waza ( 腰技 , hip techniques) throws that predominantly use

3348-726: The tournament of the penalized player. A number of judo practitioners have made an impact in mixed martial arts . Notable judo-trained MMA fighters include Olympic medalists Hidehiko Yoshida (Gold, 1992), Naoya Ogawa (Silver, 1992), Paweł Nastula (Gold, 1996), Makoto Takimoto (Gold, 2000), Satoshi Ishii (Gold, 2008), Ronda Rousey (Bronze, 2008), and Kayla Harrison (Gold, 2012 and 2016), former Russian national judo championship bronze medalist Fedor Emelianenko , Yoshihiro Akiyama , Don Frye , Rick Hawn , Daniel Kelly , Hector Lombard , Karo Parisyan , Ayaka Hamasaki , Antônio Silva , Oleg Taktarov , Rhadi Ferguson , Dong-Sik Yoon , and Khabib Nurmagomedov . Kano Jigoro's Kodokan judo

3410-405: The winner. After three shidos are given, the victory is given to the opponent, constituting an indirect hansoku-make (反則負け – literally "foul-play defeat"), but does not result in expulsion from the tournament. Note: Prior to 2017, the 4th shido was hansoku-make. If hansoku-make is awarded for a major rule infringement, it results not just in loss of the match, but in the expulsion from

3472-399: The wisdom and possibility of judo being introduced with other games and sports at the Olympic Games. My view on the matter, at present, is rather passive. If it be the desire of other member countries, I have no objection. But I do not feel inclined to take any initiative. For one thing, judo in reality is not a mere sport or game. I regard it as a principle of life, art and science. In fact, it

He was, however, acutely conscious of the Japanese public's negative perception of jujutsu: At the time a few bujitsu (martial arts) experts still existed but bujitsu was almost abandoned by the nation at large. Even if I wanted to teach jujitsu most people had now stopped thinking about it. So I thought it better to teach under

3596-469: Was awarded for holds of longer than 15 seconds and yuko for holds of longer than 10 seconds). Formerly, there was an additional score that was lesser to yuko, that of Koka ( 効果 ) . This has since been removed. If the scores are identical at the end of the match, the contest is resolved by the Golden Score rule. Golden Score is a sudden death situation where the clock is reset to match-time, and

He married Sadako Kano, daughter of the owner of Kiku-Masamune sake brewing company and was adopted by the family, changing his name to Kano. He ultimately became an official in the Shogunate government. Jigoro Kano had an academic upbringing and, from

3720-662: Was given the densho ( 伝書 , scrolls) of the Fukuda dōjō. Kano chose to continue his studies at another Tenjin Shin'yō-ryū school, that of Iso Masatomo ( c.  1820 –1881). Iso placed more emphasis on the practice of "kata", and entrusted randori instruction to assistants, increasingly to Kano. Iso died in June 1881 and Kano went on to study at the dōjō of Iikubo Tsunetoshi (1835–1889) of Kitō-ryū ( 起倒流 ) . Like Fukuda, Iikubo placed much emphasis on randori , with Kitō-ryū having

3782-858: Was introduced at the Olympics in 1988 as a demonstration event, and an official medal event in 1992 . Judo was introduced as a Paralympic sport at the 1988 Summer Paralympics in Seoul , with women's events contested for the first time at 2004 Summer Paralympics . Judo was an optional sport included in the three editions of the Commonwealth Games : 1990 Commonwealth Games in Auckland, 2002 Commonwealth Games in Manchester and 2014 Commonwealth Games in Glasgow.
