Even when a ball rolls it maintains its centre, and that is true of the Yoseikan Aikidoka when performing sacrifice throws.

Before World War II, aikido students were required to have previously studied martial arts, and have a letter of reference from their instructor.

This meant that all pre-war students already possessed basic skills of uke (the attacker), including falling and striking.

Yoseikan has a very logical structure, which can be seen as a fundamental influence of Jigoro Kano, who stressed the science of judo.

He was appointed supervisor of the uchi deshi, and also served as a teaching assistant, Ueshiba even suggested that Mochizuki marry his daughter and hence become his successor.

The characteristics of Mochizuki's Yoseikan Budo was still in essence aikido, with the addition of more Judo techniques, specifically ground work, the development of more sacrifice throws, and the inclusion Katori Shinto Ryu in higher grades.

Europe's introduction to aikido and its association with judo came about directly due to the early activities of Mochizuki.

He was to set a pattern that would be repeated in most European countries where aikido would cast its roots within the existing judo community.

A large number of early European practitioners were judoka who were past their competitive years and found the graceful techniques of aikido to be a perfect alternative allowing them to continue active martial arts practice.

Mochizuki spent a total of two-and-one-half years in France and his efforts sowed the seeds for the development of the world's largest aikido population outside Japan.

French and European Tai-jitsu is considered as a "cousin discipline" of martial arts taught in Yoseikan Ryu.

The Italian Aikido Federation was established, chaired by the lawyer Ezio Viarana and whose technical director was the master Murakami Tetsuji (1927 - 1987), a pupil of Mochizuki Shihan.

After the death of Mochizuki Shihan, the master Sugiyama, his senior pupil, developed the Yoseikan Aikijujitsu Sugiyama-ha method: this method has been recognized by the FIJLKAM (Italian Federation of Judo, Wrestling, Karate and Martial Arts) and is actually taught in Italian Dojos.

When Huntsville officers learned that Demizu was an aikido man, they asked him to begin teaching and he agreed.

Glenn Pack, now the technical director of the United States Yoseikan Budo Association (USYBA) started training around this time.

Pack continued teaching at the University of Alabama until 1975, when he went to graduate work in Arkansas, leaving the Tuscaloosa class in the hands of Rick Moncrief.

Currently there are 8 schools listed under the International Yoseikan Budo Federation (IYBF) in Canada and the US, most have the word aikido in their title.

In 1968 a gentleman by the name of Phillipe Boiron began teaching Yoseikan Aikido for Jan de Jong in Perth, Western Australia.

This lead Jan de Jong to travel to Japan in 1969 to train directly under Minoru Mochizuki for approximately 3 months receiving the rank of Shodan.

In 1974, on an official request from Jan de Jong, Mochizuki dispatched Yoshiaki Unno to Perth to teach Yoseikan Aikido.

In 1976 Yoshiaki Unno left Jan de Jong Self Defence School and opened his own dojo teaching Iaido, Kobudo, Karate and Aikido.

On the 08/10/1968, Master Le Van Nhi established a dojo under the name Aikibudo at the Sports Club in Saigon (CSS), 55 Red Cross, this is The department of Culture and Labor now.

Below is a list of common attacks used in Yoseikan, excluding strikes and kicks which encompass all of the basics from karate.
