Yoseikan Budo ("the house in which is taught with courage and honesty
the way of the warrior") was founded in the early 60's by Hiroo
Mochizuki Sensei, son of Minoru Mochizuki, one of the great martial
artists of the 20th century. Mochizuki Hiroo Sensei has high Dan
rankings in several martial arts, among them Aikido, Jujutsu, Wado-Ryu
Karate, and Iaido. Yoseikan Budo is today spread throughout Europe,
Africa and the USA. The FYBDA (Federation Internacional de Yoseikan
Budo et Disziplines Asimilees) is the worldwide umbrella organization,
which is subdivided in national Academies and regional federations.
Mochizuki Hiroo Sensei realized that most basic techniques are based
on a wavy movement beginning in the hip, which produces much more
power than when movement is limited to only extremities. These basic
elements are taught and applied to all YB techniques. YB consists of
(modified) techniques of Karate, Judo/Ju-Jutsu and Aikido. The use of
classical weapons as Bokken, Tanto, Bo, Nunchaku etc is taught as well
as traditional and new forms (kata). Beginners usually study basic
techniques for a year or so, including mae-geri, mawashi-geri etc,
nage-waza, falls, foot-work, kata, etc. From 3rd Kyu to 1st Kyu more
aikido-techniques and the use of weapons are taught. Competitions are
held and consist of Kata, Randori, Tanto-Tanto, etc.
There was a split of the umbrella organization in the early years,
leading to a sub-style (found primarily in the UA) with the name YB
that focuses primarily on Aikido-techniques.
