About Yoseikan Aikido
Yoseikan aikido is a composite style created by Minoru Mochizuki (1907–2003). Mochizuki studied judo under Jigoro Kano and in 1930 Kano sent him to Morihei Ueshiba, whose uchideshi he was for about a year. In November 1931 the Yoseikan dojo was built for him in Shizuoka. According to Stanley Pranin, he was then teaching Daito-ryu aikijujutsu and developed the composite system only after the war. According to the style's federation, Yoseikan draws on Ueshiba's prewar Aiki Budo and also on judo, aikijujutsu, karate, jujutsu, kenjutsu, Katori Shinto-ryu and other schools, and techniques are practiced empty-handed and with weapons. In 1970 and 1971 Mochizuki wrote four kata, and alongside them training relies on the study of techniques and on free practice, randori. For dan grades he introduced his own black belt with a red stripe. He remained organizationally independent of the Aikikai. In 1951 Mochizuki went to France to teach judo and is usually named the first to teach aikido in the West. The first official representative of the Aikikai arrived there in 1952. His son Hiroo Mochizuki developed Yoseikan Budo, which, unlike the Aikikai, includes competitions.
History
Minoru Mochizuki was born in 1907 in Shizuoka, and sources differ on his birthday, giving anything from 7 to 11 April. In 1930 Jigoro Kano sent him to study with Morihei Ueshiba, and Mochizuki spent about a year as his uchideshi at the Kobukan dojo. In November 1931, while recovering from pleurisy and tuberculosis of the lungs, his brother and friends built him the Yoseikan dojo in Shizuoka. In June 1932 he received two scrolls from Ueshiba, Daito-ryu Aiki Bujutsu and Hiden Ogi. According to Stanley Pranin, he was then teaching Daito-ryu aikijujutsu and developed the composite Yoseikan system only after the war. In 1951 he went to France to teach judo and is usually named as the first person to teach aikido in the West. Sources put his stay at between one and two and a half years. Tadashi Abe, the first official representative of the Aikikai, arrived in France in 1952. The founder's son Hiroo Mochizuki taught in France in 1957 and 1958 and returned in 1964. Minoru Mochizuki died on 30 May 2003 in southern France.
How it differs
Yoseikan differs from Aikikai aikido in its breadth. It is a composite style that adds judo, karate and weapons work to aikido, and Mochizuki remained organizationally independent of the Aikikai Hombu Dojo, although he kept in contact with Ueshiba until Ueshiba's death in 1969. The genealogy that Yoseikan gives runs from Saigo Chikamasa through Takeda Sokaku and Ueshiba to Mochizuki. According to its own website, the Aikikai has no competitions that decide higher and lower levels. Hiroo's branch, Yoseikan Budo, does have competitions, and in that it comes close to Tomiki aikido, where according to Britannica competitors score points by touching with a rubber or wooden knife.
Technique
Yoseikan is a composite style. According to the International Yoseikan Budo Federation, it draws on Morihei Ueshiba's prewar Aiki Budo and also on judo, aikijujutsu, karate, jujutsu, kenjutsu, Katori Shinto-ryu, Gyokushin-ryu, iaijutsu, kendo, yari spear work and Kito-ryu. Techniques are performed both empty-handed and with weapons. In 1986 Mochizuki demonstrated in Tokyo sutemi techniques from Gyokushin-ryu combined with taisabaki evasions from aikido. In 1970 and 1971 Mochizuki wrote down four kata of Yoseikan. Tai sabaki no kata shows how body movements relate to the unbalancing kuzushi, the entry tsukuri and the execution kake. The name Hyori no kata refers to the front side hyo and the back side ri, and Patrick Augé interprets it as forms of complementing.
Training
Mochizuki saw kata as a foundation to build on. In Patrick Augé's account, kata is only one part of training, next to technique study (kenkyu), free practice (randori) and demanding practice (shugyo). Augé contrasts this with Ueshiba, who in his view did not encourage kata for fear that students would get stuck in forms without understanding. Pranin says the philosophy of Yoseikan was shaped by Kano's emphasis on character over victory and by Ueshiba's spiritual outlook. Mochizuki taught in his Shizuoka dojo almost to the end of the millennium.
Ranks and progression
Yoseikan uses Jigoro Kano's system of colored belts and dan grades from judo. The black belt with a red central stripe for 1st to 5th dan was introduced by Mochizuki in the nineteen-fifties, to set Yoseikan aikido apart from judo out of respect for Kano. For 6th to 8th dan a red and white belt with a red stripe is worn, and for 9th and 10th dan a red belt with a yellow stripe. In the North American IYBF, examinations are usually held twice a year and are not compulsory, and a grade holds while the practitioner stays active. Mochizuki himself held 10th dan in aikido, 9th dan in jujutsu and 8th dan in iaido, judo and kobudo.
Today
Minoru Mochizuki's successor is his son Hiroo, whose Yoseikan Budo differs in including competitions. The Italian national Yoseikan Budo championship was held for the first time in Rome in April 2024. In North America the International Yoseikan Budo Federation operates from Torrance, California, with Patrick Augé as technical director. The federation is affiliated with the Japanese Kokusai Budo Seifukai, led by Mochizuki Tetsuma.
Did you know
The name Yoseikan is written with three characters for learning and flourishing, truth or correctness, and building, and it was chosen by a family friend of Mochizuki, a philosophy teacher. Pranin says Ueshiba attended the dojo opening in November 1931. The dojo burned down during the war and was rebuilt. Mochizuki lived about eight years in Mongolia, where he worked as an educator. Pranin says Ueshiba offered him his daughter's hand and the role of successor, but Mochizuki refused. In judo, Kyuzo Mifune accepted him as an uchideshi after he fell into a frozen well during winter kangeiko training.
