context_section_description: Aikido
  Aikido was created and developed by Morihei Ueshiba in first half of the 20th century.
  Judo
  It was created as a physical, mental and moral pedagogy in Japan, in 1882, by Kanō Jigorō.
  Jujutsu
  Jujutsu, the "way of yielding", is a collective name for Japanese martial art styles including unarmed and armed techniques. Jujutsu evolved among the samurai of feudal Japan as a method for defeating an armed and armored opponent without weapons. Due to the ineffectiveness of striking against an armored opponent, the most efficient methods for neutralizing an enemy took the form of pins, joint locks, and throws. These techniques were developed around the principle of using an attacker's energy against him, rather than directly opposing it.
  Karate
  It began as a common fighting system known as "ti" (or "te")  among the pechin class of the Ryukyuans. There were few formal styles of ti, but rather many practitioners with their own methods. One surviving example is the Motobu-ryū school passed down from the Motobu family by Seikichi Uehara. Early styles of karate are often generalized as Shuri-te, Naha-te, and Tomari-te, named after the three cities from which they emerged.
  Ninjutsu
  Developed by groups of people mainly from the Iga Province and Kōka, Shiga of Japan. Throughout history, many different schools (ryū) have taught their unique versions of ninjutsu. An example of these is the Togakure-ryū. This ryū was developed after a defeated samurai warrior called Daisuke Togakure escaped to the region of Iga. Later he came in contact with the warrior-monk Kain Doshi who taught him a new way of viewing life and the means of survival (ninjutsu).
  Okinawan martial arts
  In the 14th century, when the three kingdoms on Okinawa (Chūzan, Hokuzan, and Nanzan) entered into a tributary relationship with the Ming Dynasty of China, Chinese Imperial envoys and other Chinese arrived, some of whom taught Chinese Chuan Fa (Kempo) to the Okinawans. The Okinawans combined Chinese Chuan Fa with the existing martial art of Te to form Tō-de (唐手, Okinawan: Tū-dī, Tang hand), sometimes called Okinawa-te (沖縄手). By the 18th century, different types of Te had developed in three different villages - Naha, Shuri, and Tomari. The styles were named Naha-te, Shuri-te, and Tomari-te, respectively. Practitioners from these three villages went on to develop modern karate.
  Sumo
  Sumo is said to have started in the Heian period (794-1192). The imperial family watches sumo as a form of entertainment. It has evolved over the centuries with professional sumo wrestlers appearing in the Edo period (1603-1868).It may have been based from Mongolian, Chinese, and Korean wrestling. The word sumo is written with the Chinese characters or Kanji of  “mutual bruising."
