Our Instructors


At Rugby Ninjutsu we pride ourselves on providing the highest possible standard of martial arts tuition available, due to this the expectations of our instructors are much higher than conventional sports martial arts systems. After all we aren’t training to score points in a controlled arena but training to survive the often harsh realities of modern society.

So how do we differ from other martial arts schools?

Each of our instructors has earned their place! Racking up thousands of hours of study and training over the years! Ranks are never given out freely but are strived for and achieved with hard work and dedication!

We expect our instructors to have comprehensive knowledge of 9 schools of unarmed combat (Ku Ryuha), 18 skills (Bugei Juhappen), the use and application a huge variety of traditional Japanese weaponry, strategy and tactics, mixed martial arts, understand and teach complex Japanese, the law and much more. Most of the Bujinkan Shihan (15th Dan) have been training for over 30 years.

This doesn’t mean it’s unobtainable but you definitely earn your black belt (Shodan/1st Dan) and the right to be called a Ninja!

The key difference is our lesson times are longer, We train harder and expect more from our students but keep lessons fun, engaging and energetic.

We don’t just claim to train mini ninjas, we actually do! The results speak for themselves! We have some exceptional students!

All instructors are fully qualified insured and DBS checked to work with children. A copy of our safeguarding policy can be found in the lessons section of the website.

If you enjoy you two free taster sessions, your first month of lessons is included with your membership and you also receive a free uniform, free belt and free copy of our book (The Principles of Heaven, Earth and Ninja available on Amazon).
