The above styles can trace their lineage through senior students back to the founder of aikido, Morihei Ueshiba. Two other prominent martial arts use the name aikido but are not directly related. They are Korindo aikido founded by Minoru Hirai (平井 稔 "Hirai Minoru", 1903–1998) and Nihon Goshin aikido (日本護身合気道 "Nihon Goshin Aikidō") founded by Shodo Morita 書道森田 ("Morita Shodo", fl. c. 1930s–1962). These schools, with some historical justification, suggest that the name aikido is not the exclusive domain of arts derived from the teachings of Morihei Ueshiba.
