Morihiro Saito (斉藤 守弘 Saitō Morihiro, March 31, 1928–May 13, 2002) was a teacher of the Japanese martial art of aikido, with many students around the world. Saito's practice of aikido spanned 56 years, from the age of 18, when he first met aikido founder Morihei Ueshiba, until his death in 2002.
Meeting aikido's founder
By July 1946, the GHQ-imposed ban upon the practice of martial arts had forced Morihei Ueshiba into an official "retirement" from practice for several years. Ueshiba took this opportunity to seclude himself in the small town of Iwama, and was engaged in the practice of ascetic training (shugyō), and some believe that it was during this period that Ueshiba was perfecting the practice of aikido.
It was at this time, at the age of 18, that Saito joined Ueshiba for training, which already included then live-in students Kisshomaru Ueshiba, Koichi Tohei, and Tadashi Abe. This early training was quite brutal, but after persevering for several years, Saito became one of Ueshiba's closest students. Much credit is given to the fortuitous work schedule Saito had with the Japanese National Railways, where Saito worked 24 hours on, 24 hours off. As a result, Saito was often the sole training partner of Ueshiba, and had the unique opportunity to train with Ueshiba in the practice of the sword and short staff, which occurred early each morning before the other students arrived.
