Master Hiroo Mochizuki, who inherited his knowledge from many generations of experts in martial arts, received the basis of his knowledge in Aikido (8.Dan), Ju-Jitsu (8.Dan), Iaido (7th Dan), Judo (3rd Dan).

His father officially gave him his title of Soke of the Yoseikan School in summer 2000. Master Hiroo Mochizuki also received a solid training in Karate in which he practiced different styles that he introduced in Europe in the 50's. Through a rich and exceptional career, started during his childhood by Master Ueshiba with many other famous Japanese masters, his knowledge in a large variety of martial arts made him understand their potential to develop adaptation and creativity.

He then made his best to improve the learning process of these qualities that he thought were essential within our modern society.

His personal reflection made him create an original method composed of two parts: the martial part and the sports part (including a kind of specific competition made in the same purpose). He presents, with the World Technical Director: Mario Ambrosini and his oldest son: Mitchi Mochizuki, respectively 6th and 4th Dan YWF, both state graduated teachers, a section of the martial part of Yoseikan Budo: Happoken Godan, Hasshakuken Yodan (2 Kata without weapons) Kyoei Landoli, Tonfa and Iai Kumidatchi. The sports part is dealt with in another video entitled: Yoseikan Budo competition.
