Karate is a Japanese martial art and combat sport centred primarily on striking techniques, including punches, kicks, blocks and controlled movement, with different styles also incorporating sweeps, throws, joint manipulation or other techniques to varying degrees. The word karate is commonly written with Japanese characters meaning empty hand, reflecting the modern interpretation of fighting without conventional weapons.
Karate developed historically in the Ryukyu Islands, particularly Okinawa, through interactions among indigenous fighting traditions and Chinese martial arts, before being systematised and spread more widely in Japan. Modern karate includes both traditional practice and competitive formats, with kata and kumite being two major components. Kata involves formalised sequences of techniques, while kumite involves sparring under rules designed to control competition.
The historical development of karate is complex and cannot be reduced to a single founder or invention date. Okinawan martial traditions commonly associated with terms such as Te interacted with Chinese martial arts and subsequently developed into different regional and family traditions. During the twentieth century, Okinawan teachers such as Gichin Funakoshi played important roles in introducing karate to mainland Japan, where it was adapted to educational and institutional settings. Different teachers developed distinct styles, including Shotokan, Goju ryu, Shito ryu and Wado ryu, each with its own technical emphasis and historical lineage. Modern karate therefore represents a family of related systems rather than one completely uniform curriculum.
Karate techniques include punching, kicking, blocking, striking and movement designed to control distance and create opportunities for attack or defence. Straight punches such as the choku zuki, reverse punch or gyaku zuki and front kicks such as mae geri are common across many systems, although terminology and execution differ. Karate training often emphasises stance, hip rotation, posture, balance, timing, breathing and precise body mechanics. Traditional practice can involve repetitive technical drills designed to develop form and coordination. The emphasis on exact movement can make karate look highly formal, but the underlying purpose is to develop controlled and efficient movement that can be adapted to particular applications and competitive contexts.
Kata is one of karate's defining training and competitive forms. A kata is a predetermined sequence of movements representing combinations of offensive and defensive techniques performed against imagined opponents. Practitioners are assessed on factors such as technical execution, stance, balance, timing, rhythm, power, control and overall performance depending on the competition rules. Traditional practitioners may also study bunkai, which refers to the analysis or application of movements contained within a kata. Different karate styles have different kata, and the same or similarly named kata can have stylistic differences. Kata therefore preserves technical knowledge while also functioning as a method of individual practice and, in some settings, formal competition.
Kumite is the sparring component of karate and can take many forms depending on the style and ruleset. Competitive sport karate commonly uses controlled techniques and scoring systems that reward appropriately executed attacks to permitted target areas. Traditional dojo sparring can use different degrees of contact and different rules. Some karate styles emphasise distance and precise linear attacks, while others incorporate closer exchanges, sweeps or combinations. Because the rules vary, a statement that karate competition always involves the same type of contact or scoring would be inaccurate. Athletes must understand the particular rules of their style and competition.
Karate training also includes physical conditioning and mental discipline. Repetition can develop coordination, flexibility, balance, speed and strength, while controlled sparring develops timing, distance management and reactions. Traditional karate places importance on etiquette, discipline, respect and self control, and many dojos use formal procedures such as bowing and structured commands. Rank systems using coloured belts and black belt grades are common, although exact grading structures differ among organisations. Progression through grades generally reflects technical knowledge, practical ability, discipline and experience, but belt systems should not be interpreted as perfectly standardised indicators across all karate organisations.
Karate's influence extends beyond competition. It is practised for fitness, self defence education, cultural interest, discipline, recreation and competitive performance. However, sport karate and practical self defence are not identical. Competition rules deliberately restrict certain actions to create a manageable sporting environment, while real world situations are unpredictable and do not provide referees, weight classes or agreed boundaries. Similarly, cinematic depictions of karate often exaggerate the speed or effects of techniques. Serious karate training is normally based on repetition, timing, controlled contact, technical precision and progressive learning rather than theatrical movement.
Modern karate includes many organisations and styles, so its techniques, terminology, kata curricula, contact rules and competitive formats can differ significantly. International sport karate has included disciplines such as kata and kumite, while traditional organisations may place greater emphasis on historical forms, philosophy and practical applications. Karate's international development culminated in its inclusion as an Olympic sport at the Tokyo 2020 Games, held in 2021, although its Olympic status should not be treated as representing every traditional karate organisation. The broad concept remains a Japanese and Okinawan striking art characterised by disciplined movement, formal technique, striking skill and diverse approaches to training and competition.
