Welcome to my wordpress blog, which is where I share short articles on personal safety and karate.

I’m a best-selling martial arts author, international coach and training advisor, co-curricular education specialist, two-time transplant survivor and nerd.

You can watch short previews of some of my work on my youtube channel, read some helpful tips here on my blog, or visit my website to become a supporter and see more of what I share in my books and international seminars. 🙂

Want to know more about what I do?

A brief look at what I do…

I’m best known internationally for the realistic safe scenario simulation  training that I run and my focus on legally underpinned self defence, but have also gained widespread recognition in the karate community for writing six critically acclaimed best-selling books on the effective application of traditional karate kata.

My seminars, books, youtube videos and articles have become very popular with the growing number of groups and individuals looking to enhance their own training through a pragmatic approach to the practical application of traditional martial arts for effective self defence. In addition to my regular classes I travel to lecture and teach and am lucky enough to have taught in the UK, USA, Canada and Europe.

I am a member of the British Combat Association (one of the world’s leading groups for close-quarter combat, self-protection and practical martial arts) and the Chief Instructor of the Practical Karate Association. I’m fortunate to have great friends in a number of different martial arts, security and law enforcement fields with whom I share ideas and who encourage and help me in my own training.

In addition to my best-selling books, I have been a regular contributor for Traditional Karate Magazine, Combat Magazine and Jissen. When I’m not training, relaxing or doing voluntary work, I focus on researching and producing material for this blog and more in-depth articles and videos for my supporter community.

    Hi John, I can’t get an email to go through your DART site. I wanted to enquire about open seminars using your pressure testing system and the protective equipment etc. I can’t find details on the seminar link, I’m hoping that you run these for non-DART members from time to time. Please could you let me know how I can find out details. Many thanks

    1. Hi Gareth

      Sorry. I’d made some changes to the website recently and unwittingly deleted an email link. There is now an email link at the bottom of the seminars page.

      Most of the participants on my pressure testing days are not my students and I am in the process of arranging some more dates with my normal venue.

      All the best


  2. Hi John,

    I find your research and Bunkai very enlightening. I was wondering if you have ever heard of ‘Pinan Dai; The Great Pinan’, This is all 5 Pinan kata done at the same time to form something similar to a Tai Chi form.

    I feel that what you are doing is what this (Karate) is all about.

    Keep it up!

    1. Hi David

      Thank you for your kind comments.

      Not by that name. I’ve done all the forms back to back in the past and abbreviated versions joined together, however I’ve never seen anything in my own research that would indicate that historically the five Pinan were a single form or indeed originate from a single form. I see them as new forms, originally called Channan, later Pinan, later Heian, plausibly with originally two different creators at two separate times (one creating the first two forms, the other adding the latter three and tweaking all the version throughout the time period he taught them). The forms have obviously been changed slightly in every single style that has since adopted them. While they can be done by children, I do not regard them as children’s forms, rather I regard them as ‘new’ core forms – the equivalent of Naihanchi and Sanchin.

      All the best

    I have been working through your first Pinan Flow System book and was wondering: what is the difference between your Heian Flow System book and your Pinan Flow System books? For instance, if someone has read the Pinan Flow System series, is there any additional material in the Heian book? If you have covered this elsewhere please let me know. Thanks,


    1. Hi Stephen

      The Pinan Flow System is very different to the Heian Flow System. There’s about at 15% overlap in the physical drills with different strategies employed in each with differing training methodologies. The PFS is a result of a further decade of focusing on self defence related practice. The HFS has a bigger HAOV section. The HFS is now out of print though some retailers may carry copies. The HFS has a different layout reflected in the printing costs and technology of a decade a go with smaller darker pictures than its modern 4 book series counterpart.

      I’ve said a little bit about this in a blog article here about the release of the first book in the PFS series.

      All the best
