Judo

 Judo was established in samurai society since the 12th century. Judo has evolved in the Edo period after the Warring States period. Now it has become one of the most widely practiced martial arts in Japan. The philosophy and subsequent pedagogy developed for judo became the model for other modern Japanese martial arts that developed from koryu (traditional schools). The worldwide spread of judo has led to the development of a number of offshoots such as Sambo and Brazilian Jiu-Jitsu. Practitioners of judo are called judoka.
 There are two game style "Kata(forms)" and "Randori(free practice)". There are three basic categories of waza (techniques) in Judo: nage-waza (throwing techniques), katame-waza (grappling techniques) and atemi-waza (striking techniques). Judo is most known for nage-waza and katame-waza. There is also ukemi-waza(break-falls techniques) to prevent injury.
