context_page_description: Daitō-ryū Aiki-jūjutsu, originally called Daitō-ryū Jujutsu, 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 and referred to the style he taught as "Daitō-ryū". 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.
context_section_description: The last major group consists of students of Yukiyoshi Sagawa (佐川 幸義, Sagawa Yukiyoshi, 1902–1998), who was once considered to be the successor to Takeda Sokaku (should Tokimune not have survived World War II). Sagawa ran only a single dojo and taught a relatively small number of students.  He began studying Daitō-ryū under Takeda Sokaku in 1914 after first learning the art from his father, Sagawa Nenokichi (1867–1950), who was also a student of Sokaku and a holder of a Kyōju Dairi (teaching license) in the system. Although considered by many to be one of the most accomplished students of Sokaku, Yukiyoshi Sagawa received the kyoju dairi in 1932—but did not receive the menkyo kaiden (certificate of mastery) of the system's secrets, as during the time he practised under Takeda Sokaku, the highest licence was not the menkyo kaiden. Sagawa often served as a teaching assistant to Takeda and traveled with him to various locations in Japan teaching Daito-ryu. He further developed the art of applying Aiki and is said to have remained powerful until very late in life, and – as a consequence of the success of Transparent Power – was featured in a series of articles in the Aiki News magazines prior to his death in 1998.
  Tatsuo Kimura (木村 達雄 Kimura Tatsuo, born 1947), a former mathematics professor at the University of Tsukuba and a senior student of Sagawa, ran a small aiki-jūjutsu study group at that institution. He retired from his professorship there in June 2013, and has retired from public instruction of Daito Ryu. He now privately instructs a small group of students. He has written two books about his training under Sagawa: Transparent Power and Discovering Aiki. 
  Daisuke Nagano, a descendant of Narimasa Nagano and noted Master of Asayama Ichiden Ryu under Yukio Nakamura and senior student of Sagawa, taught at Koikikawa Dojo near Tokyo and often taught United States military servicemen stationed in Okinawa in the 1970s. In the 1997 a branch dedicated to Nagano sensei's teachings called "Nagano Ryu Heihou Kyokai" was founded by his most senior student Jamie Ellerbe.
