The last major group consists of students of Yukiyoshi Sagawa (佐川 幸義, ''Sagawa Yukiyoshi'', 1902&ndash;1998), who was once considered to be the successor to Takeda Sokaku (should Tokimune not have survived World War II).{{citation needed|date=February 2010}} 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,<ref name="Pranin-Sagawa">{{cite encyclopedia|last=Pranin |first=Stanley |title=Sagawa, Yukiyoshi |encyclopedia=Encyclopedia of Aikido |year=2006 |url=http://www.aikidojournal.com/encyclopedia?entryID=563 |access-date=20 July 2007|url-status=dead |archive-url=https://web.archive.org/web/20070926225632/http://www.aikidojournal.com/encyclopedia?entryID=563 |archive-date=26 September 2007}}</ref> 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&nbsp;– as a consequence of the success of ''Transparent Power''&nbsp;– was featured in a series of articles in the Aiki News magazines prior to his death in 1998.<ref name="Pranin-Sagawa"/>

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''.<ref>{{cite journal|last=Wollos |first=Paul |title=Report on Sagawa-ha Daito-ryu Aikibujutsu |journal=Aikido Journal |url=http://www.aikidojournal.com/article.php?articleID=242 |access-date=20 July 2007 |url-status=dead |archive-url=https://web.archive.org/web/20071013161512/http://www.aikidojournal.com/article.php?articleID=242 |archive-date=13 October 2007}}</ref>
