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 was no longer of practical use. Another frequent visitor, Imai Genshiro of school of jujutsu, also refused.

where he taught five students. Fukuda is said to have emphasized technique over formal exercise, sowing the seeds of Kano's emphasis on in judo.
On Fukuda's death in 1880, Kano, who had become his keenest and most able student in both ''randori'' and , was given the of the Fukuda dōjō. Kano chose to continue his studies at another ''Tenjin Shin'yō-ryū'' school, that of Iso Masatomo (–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 .

Judo versus Jujutsu
Central to Kano's vision for judo were the principles of and . He illustrated the application of ''seiryoku zen'yō'' with the concept of :
![Judo](https://upload.wikimedia.org/wikipedia/commons/4/45/Judo.svg)
Kano realised that ''seiryoku zen'yō'', initially conceived as a jujutsu concept, had a wider philosophical application. Coupled with the

-influenced ''jita kyōei'', the wider application shaped the development of judo from a to a . Kano rejected techniques that did not conform to these principles and emphasised the importance of efficiency in the execution of techniques. He was convinced that practice of jujutsu while conforming to these ideals was a route to self-improvement and the betterment of society in general. He was, however, acutely conscious of the Japanese public's negative perception of jujutsu:
Kano believed that "''jūjutsu'' was insufficient to describe his art: although means "art" or "means", it implies a method consisting of a collection of physical techniques. Accordingly, he changed the second character to , meaning "way", "road" or "path", which implies a more philosophical context than ''jutsu'' and has a common origin with the Chinese concept of ''
tao
''Tao'' or ''Dao'' is the natural order of the universe, whose character one's intuition must discern to realize the potential for individual wisdom, as conceived in the context of East Asian philosophy, East Asian religions, or any other phil ...
''. Thus Kano renamed it .
Judo ''waza'' (techniques)
There are three basic categories of in judo: , and . Judo is mostly known for ''nage-waza'' and ''katame-waza''.
Judo practitioners typically devote a portion of each practice session to , in order that ''nage-waza'' can be practiced without significant risk of injury. Several distinct types of ''ukemi'' exist, including ; ; ; and
The person who performs a ''Waza'' is known as and the person to whom it is performed is known as .
''Nage-waza'' (throwing techniques)
''Nage-waza'' include all techniques in which ''tori'' attempts to throw or trip ''uke'', usually with the aim of placing ''uke'' on his back. Each technique has three distinct stages:
*: the opponent becoming off balanced;
*: turning in and fitting into the throw;
[Kano (1994) p. 44; Mifune (2004) p. 44]
*: execution and completion of the throw.
[
''Nage-waza'' are typically drilled by the use of , repeated turning-in, taking the throw up to the point of ''kake''.
Traditionally, ''nage-waza'' are further categorised into , throws that are performed with ''tori'' maintaining an upright position, and , throws in which ''tori'' sacrifices his upright position in order to throw ''uke''.][Daigo (2005) p. 10]
''Tachi-waza'' are further subdivided into , in which ''tori'' predominantly uses his arms to throw ''uke''; throws that predominantly use a lifting motion from the hips; and , throws in which ''tori'' predominantly utilises his legs.
''Katame-waza'' (grappling techniques)
''Katame-waza'' is further categorised into , in which ''tori'' traps and pins ''uke'' on his back on the floor; , in which ''tori'' attempts to force a submission by choking or strangling ''uke''; and , in which ''tori'' attempts to submit ''uke'' by painful manipulation of his joints.
A related concept is that of , 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'' (striking techniques)
''Atemi-waza'' are techniques in which ''tori'' disables ''uke'' with a strike to a vital point. ''Atemi-waza'' are not permitted outside of ''kata''.
Pedagogy
''Randori'' (free practice)
Judo pedagogy emphasizes . This term covers 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 , in which neither participant offers resistance to their partner's attempts to throw. A related concept is that of , in which an experienced judoka allows himself to be thrown by his less-experienced partner. At 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 (forms)
are pre-arranged patterns of techniques and in judo, with the exception 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 the Kodokan today:
* , comprising two kata:
** Fifteen throws, practiced both left- and right-handed, three each from the five categories of ''nage waza'': ''te waza'', ''koshi waza'', ''ashi waza'', ''ma sutemi waza'' and ''yoko sutemi waza''.
** . Fifteen techniques in three sets of five, illustrating the three categories of ''katame waza'': ''osaekomi waza'', ''shime waza'' and ''kansetsu waza''.
* . Twenty techniques, illustrating the principles of defence in a combat situation, performed from kneeling and standing positions. Attacks are made unarmed and armed with a dagger and a sword. This kata utilises ''atemi waza'', striking techniques, that are forbidden in randori.
* . The most recent recognised kata, comprising twenty-one techniques of defence against attack from an unarmed assailant and one armed with a knife, stick and pistol. This kata incorporates various jujutsu techniques such as wrist locks and ''atemi waza''.
* . Fifteen techniques, arranged in three sets of five, demonstrating the principle of ''Jū'' and its correct use in offence and defence.
* . One of the oldest kata, comprising ten forms that illustrate the efficient use of force and resistance. Now rarely practiced.
* . An advanced kata, illustrating the principle of ''seiryoku zen'yō'' and the movements of the universe. The kata predates the creation of Kodokan and originated in Tenjin Shinyō-ryū Tenjin may be:
* Tenjin (kami), the Shinto kami (spirit) of scholarship
* Tenjin, Fukuoka, Japan, the downtown region of the city
** Tenjin Station, a subway station
* Tenjin River, in Tottori Prefecture, Japan
* Tenjin Beach, a recreational beach ...
.
* . Derived from ''Kitō-ryū'' Jujutsu, this kata was originally intended to be performed wearing armour. Kano chose to preserve it as it embodied the principles of judo.
* . A series of exercises designed to develop the physique for judo.
* . An exercise completed in 1943, and of which the development was ordered by Jiro Nango, the second Kodokan president.
In addition, there are a number of commonly practiced kata that are not recognised by the Kodokan. Some of the more common kata include:

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 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 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.[Hoare (2005) pp. 4–7] 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

announced changes in evaluation of points. There will only be ippon and waza-ari scores given during 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 .][ A pin lasting for less than 20 seconds, but more than 10 seconds scores waza-ari (formerly waza-ari was awarded for holds of longer than 15 seconds and yuko for holds of longer than 10 seconds).][

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 the opponent is penalised (Hansoku-make).

Penalties
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 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 the tournament of the penalized player.

Alternative rulesets and derivative martial arts
Kano Jigoro's Kodokan judo 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:
*: Sometimes erroneously described as 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.

(free practice) was a central part of judo pedagogy and shiai (competition) a crucial test of a judoka's understanding of judo. Safety necessitated some basic innovations that shaped judo's development. Atemi waza (striking techniques) were entirely limited to kata (prearranged forms) early in judo's history. Kansetsu waza (joint manipulation techniques) were limited to techniques that focused on the elbow joint. Various throwing techniques that were judged to be too dangerous to practice safely at full force, such as all joint-locking throws from Jujutsu
Jujutsu ( ; ja, link=no, 柔術 , ), also known as jiu-jitsu and ju-jitsu, is a family of Japanese martial arts and a system of close combat (unarmed or with a minor weapon) that can be used in a defensive or offensive manner to kill or subdu ...

(rice straw mats).
''Kansetsu'' and ''shime waza''
The application of joint manipulation and strangulation/choking techniques is generally safe under controlled conditions typical of judo dōjō and in competition. It is usual for there to be age restrictions on the practice and application of these types of techniques, but the exact nature of these restrictions will vary from country to country and from organization to organization.
''Nage waza''
Safety in the practice of throwing techniques depends on the skill level of both tori and uke. Inexpertly applied throws have the potential to injure both tori and uke, for instance when tori compensates for poor technique by powering through the throw. Similarly, poor ukemi can result in injury, particularly from more powerful throws that uke lacks the skill to breakfall from. For these reasons, throws are normally taught in order of difficulty for both tori and uke. This is exemplified in the ''Gokyo'' , a traditional grouping of throws arranged in order of difficulty of ukemi. Those grouped in are relatively simple to breakfall from whereas those grouped in are difficult to breakfall from.
Judoka (practitioner)
A practitioner of judo is known as a . The modern meaning of "judoka" in English is a judo practitioner of any level of expertise,[Inokuma and Sato (1987) p. 253] but traditionally those below the rank of 4th ''dan'' were called ; and only those of 4th ''dan
Dan or DAN may refer to:

In Western dōjō, it is common to call an instructor of any ''dan'' grade ''sensei''. Traditionally, that title was reserved for instructors of 4th ''dan'' and above.

at the 1986 Maastricht IJF DC Meeting. For competition, a blue judogi is worn by one of the two competitors for ease of distinction by judges, referees, and spectators. In Japan, both judoka use a white judogi and the traditional red obi (based on the colors of the Japanese flag) is affixed to the belt of one competitor. Outside Japan, a colored obi may also be used for convenience in minor competitions, the blue judogi only being mandatory at the regional or higher levels, depending on organization. Japanese practitioners and traditionalists tend to look down on the use of blue because judo is considered a pure sport, and replacing the pure white judogi with the impure blue is an offense.
For events organized under the auspices of the International judo Federation (IJF), judogi have to bear the IJF Official Logo Mark Label. This label demonstrates that the judogi has passed a number of quality control tests to ensure it conforms to construction regulations ensuring it is not too stiff, flexible, rigid or slippery to allow the opponent to grip or to perform techniques.

The IJF is responsible for organising international competition and hosts the World Judo Championships and is involved in running the Olympic Judo events.
Rank and grading
Judo is a hierarchical art, where seniority of judoka is designated by what is known as the - ranking system. This system was developed by Jigoro Kano and was based on the ranking system in the board game Go.
Beginning students progress through kyu grades towards dan grades.
A judoka's position within the kyu-dan ranking system is displayed by the color of their belt. Beginning students typically wear a white belt, progressing through descending kyu ranks until they are deemed to have achieved a level of competence sufficient to be a dan grade, at which point they wear the . The kyu-dan ranking system has since been widely adopted by modern martial arts.
The ninth degree black belt ''kudan'', and higher ranks, have no formal requirements and are decided by the president of the Kodokan, Kano Jigoro's grandson Kano Yukimitsu served as the fourth president from 1980 until 2009 and died as of March 2020. As an educator by profession, Kanō believed that there should be no end to an individual's learning, and therefore no limit to the number of dan ranks. As of 2011, fifteen Japanese men have been promoted to the tenth degree black belt ''judan'' by the Kodokan, one of whom is still alive;[ the IJF and Western and Asian national federations have promoted another eleven who are not recognized (at that level of rank) by the Kodokan. On 28 July 2011, the promotion board of USA Judo awarded ]Keiko Fukuda

Kawaishi visited London and the Budokwai in 1928, and was probably inspired to bring the coloured belt system to France.]
