The Martial Art of Yoseikan Budo

Founded in 1970, by Japanese Master Hiroo Mochizuki, Yoseikan Budo draws from his vast experience in several martial arts including Karate (9th Dan), Jujutsu (8th Dan), Aikido (8th Dan), Iaido and Kobudo (7th Dan), Judo (3rd Dan), French Savate Kickboxing and English Boxing.

The Wave


Yoseikan Budo is a complete system, based around one key principle that connects all the martial arts: The Wave.

Power and speed of any martial art technique is considerably amplified by using ten different wave-like motions of the body that are unique to the Yoseikan Budo style. When performing a wave, the feet push on the ground, and the power is transferred to the hips that will direct it through the body to the target. Leg lock A correct execution of the wave utilizes a smooth combination of muscle contraction, tendon elastic energy, body weight and rotational forces for maximum penetration power, with minimum expansion of energy and therefore minimum fatigue. Through wave mastery, the practitioners also become more internally aware of their muscles, tendons, bones and joints improving their alignment and force transfer through their structure. This results in better bio-mechanics which not only improves efficiency but also preserves the anatomy of the practitioner over the years. Finally optimal wave mastery allows the practitioner to be able to develop power from short range even if the extremity is in contact with the target (e.g. the one inch punch).


Training in yoseikan budo blends and flows through:

Head kick
  • Striking (Medium Range “Ma”)
  • Grappling (Short Range “Tchikama”)
  • Weapon Training (Long Range “Toma”)
  • Striking (Punches, kicks, elbows, knees, various opened hand techniques)
  • Grappling (Standing: clinch, throws, locks, chokes. Ground: pins, sweeps, choke holds, locks.)
  • Weapons (small (Knife), medium (stick) and long (Sword) range) (Foam version for sparring). Other weapons also trained include: nunchakus, tonfa, sai, bo and jo.

The same waves are applied to all ranges of combat with the appropriate amplitude.

The Name

Yoseikan Budo

The name yoseikan has many different meanings that all convey the philosophy of both Minoru and Hiroo Mochizuki. The literal translation is “the place where what is true (or right) is taught” or to make more sense to the western mind, “the way that works best”. Yoseikan is a personal experience that may not be the same for each practitioner.

A more broken down meaning would be as follows:

  • YO: Education, food for the soul.
  • SEI: Righteousness
  • KAN: School
  • BU: Searching for peace
  • DO: The way

The Symbol

Circle: Perfection. The circle is interrupted by the bottom tip of the mountain symbolising that it is impossible to achieve perfection therefore it is important to remain modest and humble.

Yoseikan Budo Symbol

The mountain: Being grounded, solid and strong. There are many paths to the top of the mountain and each person must follow their own path.

The River: (Zigzag at the bottom of the mountain). Represents the ever changing directions of life itself and the many situations that can be experienced by each individual.

The Red: Air, Oxygen, Light

The Blue: Water, Suppleness, Calm, Adaptation, Hope.

The White: (In the mountain) Earth, Honesty, Clarity

The Outfit (Gi)


JACKET: Dark Blue, Yin (IN) negative, defence, deflect, absorb, feel, sensitive, soft

TROUSERS: White with blue strips, Yang (YO) positive, offense, power, hard, strong

BELT: White and blue, symbolises the wave. Everybody from the novice to the expert wears the same belt so there is no visual difference. This forces the practitioners to focus on their own self, their weaknesses. The technical ability of a person is only realised when training with them. Technical ability is not necessary proportional to moral value and vice versa.

Master Hiroo Mochizuki

Hiroo MochizukiBorn in 1936 in Shizuoka, Japan, Master Hiroo Mochizuki owes the basis of his knowledge in Aikido (8th Dan), Ju-Jitsu (8th Dan), Iaido (7th Dan), Judo (3rd Dan) and Kobudo to his father. In addition, he received solid training in Karate (9th Dan) and is adept in several styles: principally Karate Shotokan with Master HYOGO and Karate Wado Ryu with Masters Hironori OHTSUKA and Shinji MICHIHARA. He has also practiced French Savate Kickboxing, English boxing (with a professional champion) and has a marked interest in all martial arts, especially those Chinese as he spent some time living in China with his father.

Samurai Lineage

3 Different sized weapons

The Mochizuki family come from a samurai heritage that can be traced back directly. This is one of the main reasons that we use the 3 different sized foam weapons for sparring – the small size represents the tanto, the middle size represents the wakizashi and the big size represents the katana. The samurai were adverse to many forms of combat for the battlefield – Ken-Jutsu, Iaido and Kobudo for weapons fighting, though they also had to know unarmed combat – Jiu-Jutsu (if they were ever disarmed or without their weapons) - throws, locks and striking - which would later become known as styles such as Karate, Judo, Aikido, etc…
