The vision of World Ju-Jitsu Federation Ireland is to empower people in our community’s lives through the martial arts. To help people get in shape, be safe and instil the life skills and character of a true martial artist while upholding important values like courtesy, patience, respect, self control and integrity.


World Ju-Jitsu Federation Ireland’s purpose is to provide support to our students. We do this by helping students develop confidence, focus, self discipline and self esteem through our martial arts coaching. We support our students by teaching them both martial arts and true self-defence while helping them get in the best shape of their lives, which helps our students create a positive outlook, a spirit of constant improvement and an attitude that refuses to give up.


World Ju-Jitsu Federation Ireland promise is that with the utmost professionalism, in a safe atmosphere, and with care and respect, to uphold and teach our students the values and life skills that will lead to remarkable improvements in work/school and relationships – literally making a better community one black belt at a time.


  • Getting a child to do what they are told can be challenging enough, and our program will develop discipline and respect in your child. Developing self discipline in children is one of the most important lessons they can learn in Ju-Jitsu so they have the knowledge to know what they should do and have the self discipline to do it, also to not do something just because a peer group asked them to is an important factor – you can’t always be there but you don’t need to be if they know for themselves what is right and what is wrong! This will be invaluable as they grow into successful teens and adults.

  • A confident child is a much happier child. They no longer live in anxiety or fear. Confidence is the first step to get a child to succeed at all areas of life. Once confidence is developed, the coaches in our clubs can help them to perform at their highest possible level.

  • Children will begin by keeping their eyes focused on the eyes of people speaking to them. They will begin paying more attention to their teachers and for longer periods of time, therefore hearing and learning more. Focus is a skill and like any other skill it can be learned and developed, the more you use it, the better and stronger it gets. With martial arts training we train children to focus and concentrate at a much higher level.

Our Coaches

Our Instructors have spent many years devoted to training in Ju-Jitsu – there are no fast tracks or easy routes to becoming a coach in WJJF (Ireland). Everyone starts at the bottom and works their way up – that way they understand what you are going through in your training and will give you the support and guidance you need. Each coach has went through an extensive training programme and teach under supervision for many years before they open their own clubs. This is why they get results. They have gained a lot personally and professionally and they all have an ethos of giving back to the organisation, which is why they find it rewarding to share and pass on their knowledge to their students. This is what makes a truly motivated teacher.


Our Founder, Soke Clark was a 9th dan of Ju-Jitsu, the charismatic and technical chief of the WJJF. He was born in Liverpool on 2nd February 1946 and he started martial training when he was 6 years old. His master was Jack Britton. We owe him a debt of gratitude for the real development of ju-jitsu all around the world and the promotion of ancient schools through modern methods. He also acted as International Technical Director of WJJKO, the organization created for gathering together all ju-jitsu styles. Robert Clark developed his own ju-jitsu techniques for more than four decades. The current WJJF syllabus was written and developed by him. Having written several books and produced numerous training DVDs, he is one of the foremost authorities on effective ju-jitsu techniques.

Giacomo Spartaco Bertoletti

Shike Bertoletti started his “martial” training when he was 12 years old with Graeco-Roman wrestling and fencing (foil). He started practicing karate Shokukai, that would develop into Sankudo and Sankukai with Master Jean Michael Baroche, one of the first black belt students of Master Yoshinao Nanbu, in 1961. He practiced judo and kendo, but above all a ju jitsu style of Japanese origin: Yoshin Ryu. He also practiced Shotokan in the school of Master Hiroshi Shirai (yudanshakai) and Masaru Miura, and Shito with Sō Shihan Ogasahara Eiji (Kenshukai). In 1976, with the foundation and leadership of the WJJF (World Ju Jitsu Federation) headed by Soke Robert Clark, he started his long trips to Japan and he joined the school Hontai of Saburo Masanori Minaki, 17th Patriarch, thanks to the presentation of Sō Shihan Eiji Ogasahara, where he remained until Soke Minaki’s death (1986). He received the 7th dan Kyoshi in 1984 by the same Master Sabuno Minaki, with whom also Soke Fumon Tanaka (Nippon Koden Kobudo) trained in secrecy. In 1997 he received the 8th dan by Soke/Sosai Kunio Tatsuno of the Sheshinkai of Osaka. In 2004 President Paul Hoglund (President of JJIF, International Ju Jitsu Federation) issued him the 9th dan grade. His career successes culminated on April 2005 (Venice) when he was granted 5th Shike  title of the school Koden ENSHINRYU Honmon ENSHINRYU-BUJUTSU, an honorary and dynastic title that only a few western persons can get.

David Toney

President of WJJF (Ireland)
David Toney is the President of WJJF (Ireland) his title Kai cho translates to ‘President’ or more literally: ‘head of house’ or ‘head of the family’. This title is very fitting as World Ju-Jitsu is one large family which works together for the betterment of all. David started training in 1982 and quickly was hooked on learning as much as he could. So much so, that he travelled to England once a month to train with Soke Robert Clark (until his passing) and brought his teachings to the students in Ireland. He, along with his wife Anne, have hosted the WJJF/WJJKO World Congress twice and he travels extensively, not only in Ireland but around the World, passing on the knowledge that was passed to him. David holds the grade of 8th Dan, and is supported by an ever-growing team of highly technical coaches who, like him, want to pass their knowledge to others. To quote our Soke regarding his Federation, and using his analogy of a large family – ‘you are bred into World Ju-Jitsu’ – and here at World Ju-Jitsu Federation Ireland – we place paramount importance on taking very good care of every one of our family members.
