Japanese martial art in the context of "Jujutsu"

Morihei Ueshiba (植芝 盛平, Ueshiba Morihei; December 14, 1883 – April 26, 1969) was a Japanese martial artist and founder of the martial art of aikido. He is often referred to as "the founder" Kaiso (開祖) or Ōsensei (大先生/翁先生), "Great Teacher".

The son of a landowner from Tanabe, Ueshiba studied a number of martial arts in his youth, and served in the Japanese Army during the Russo-Japanese War. After being discharged in 1907, he moved to Hokkaido as the head of a pioneer settlement; here he met and studied with Takeda Sōkaku, the headmaster of Daitō-ryū Aiki-jūjutsu. On leaving Hokkaido in 1919, Ueshiba joined the Ōmoto-kyō movement, a Shinto sect, in Ayabe, where he served as a martial arts instructor and opened his first dojo. He accompanied the head of the Ōmoto-kyō group, Onisaburo Deguchi, on an expedition to Mongolia in 1924, where they were captured by Chinese troops and returned to Japan. The following year, he had a profound spiritual experience, stating that, "a golden spirit sprang up from the ground, veiled my body, and changed my body into a golden one." After this experience, his martial arts technique became gentler, with a greater emphasis on the control of ki.

Iaidō (居合道), abbreviated iai (居合), is a Japanese martial art that emphasizes being aware and capable of quickly drawing the sword and responding to sudden attacks.

Iaido consists of four main components: the smooth, controlled movements of drawing the sword from its scabbard (or saya), striking or cutting an opponent, shaking blood from the blade, and replacing the sword in the scabbard. While beginning practitioners of iaido may start learning with a wooden sword (bokutō 木刀) depending on the teaching style of a particular instructor, most of the practitioners use a blunt-edged sword called an iaitō or mogitō. Few, more experienced, iaido practitioners use a sharp-edged sword (shinken).

Kendo (Japanese: 剣道, Hepburn: Kendō; lit. 'sword way' or 'sword path' or 'way of the sword') is a modern Japanese martial art, descended from kenjutsu (one of the old Japanese martial arts, swordsmanship), that uses bamboo swords (shinai) as well as protective armor (bōgu). It began as samurai warriors' customary swordsmanship exercises, and today, it is widely practiced within Japan and has spread to many other nations across the world.

Kitō-ryū (起倒流) is a traditional school (koryū) of the Japanese martial art of jujutsu. Its syllabus comprises atemi-waza (striking techniques), nage-waza (throwing techniques), kansetsu-waza (joint locking techniques) and shime-waza (choking techniques). The style is focused on throws and sweeps, and many of these techniques are designed to be performed while in full armor.

Daitō-ryū Aiki-jūjutsu (大東流 合気柔術), originally called Daitō-ryū Jujutsu (大東流柔術, Daitō-ryū Jūjutsu), is a Japanese martial art that first became widely known in the early 20th century under the headmastership of Takeda Sōkaku. Takeda had extensive training in several martial arts (including Kashima Shinden Jikishinkage-ryū and Sumo) and referred to the style he taught as "Daitō-ryū" (literally, "Great Eastern School"). Although the school's traditions claim to extend back centuries in Japanese history there are no known extant records regarding the ryū before Takeda. Whether Takeda is regarded as either the restorer or the founder of the art, the known history of Daitō-ryū begins with him. Takeda's best-known student was Morihei Ueshiba, the founder of Aikido.
