The grading syllabus can be split into two elements. Mastering the techniques that make up the art of jujutsu and applied combative application for self- defence. To be graded correctly in Japanese combat jujutsu you must have both of these elements trained.

My syllabus runs from red belt to black belt and above. Each grade gets progressively more demanding as new techniques and advanced applications are learnt.

The physical components of the art can be broken down in to sub sections. They are as follows:

  • ATEMI -WAZA – Striking and manipulation of the bodies vital points and nerve centres.

  • NAGE-WAZA- Throws and takedowns.

  • KANSETSU-WAZA -Joint locks, immobilisations.

  • TAIHO -WAZA -Arresting and control techniques.

  • KOTSU HO WAZA – Bone breaking.

  • SHIME -WAZA – Choking and strangulation.

  • NEWAZA- ground fighting.

  • KOBO-WAZA -Weapons techniques.


Most combat jujutsu techniques will incorporate one or more of these components combined.

80% of its techniques will be standing and 20% will be on the ground unlike modern day Brazilian jujutsu.

The reason for this was that original battlefield jujutsu was fought in armour and with weapons. Unarmed techniques only came into play if a weapon was lost, broken or both party’s clashed into a grapple.

Going to the ground would have been extremely dangerous.

This ideology holds truth for the combative self defence techniques of the art were again going to the ground would not be your first option in the street. We are not having a sporting grappling match with rules and regulations. The street is an unpredictable environment were the only rule is there are no rules.

Many of the sporting techniques of modern-day jujutsu would not translate well to the street, where weapons and multiple attacks are prevalent.


Additional techniques taught are of a cerebral nature.

  • Warrior mindset

  • Fear control and adrenal responses

  • The anatomy of violence

  • Streetwise awareness and tactics



If you do not have the time or inclination to learn the whole system or you are not interested in belt grades you can just learn the combative side of the art for self- defence. This may take the form of blocks of 4, or more lessons to suit your needs and goals. If you successful complete your course, you will be issued with a signed certificate as evidence that you have done it.
