Sensei Moira Barber 

Kaichou Kai Karate Association was formed in 2009 by Sensei Moira Barber, 8th Dan, who has experience teaching both traditional and sport karate. The association developed quickly and soon gained recognition for its professionalism. We are affiliated to the English United Karate Federation and The World United Karate Federation. We work closely with these groups, to maintain high standards of karate practice and provide opportunities for students to reach world class status. 



Our clubs are based in Rainham, Grays and Hornchurch. Students range from 5 years to adult. Our instructors are all DBS checked and trained in first aid. 



The meaning of Kaichou Kai is ‘Strength in Unity’, together we support, encourage and help each other in our goals.


Founder of Kaichou Kai Karate Association


Sensei Moira Barber: 8th Dan 

From her very first lesson, Moira found the discipline and strenuous training in karate very challenging, both mentally and physically. Some 40+ years later, it is apparent that these challenges developed into a passion for the art of Karate-do. She also offers personal training and sports massage.

Moira is a highly experienced instructor, who has gained knowledge over her many years of training with some of the world’s top karate-ka. She first opened the Grays dojo in 1979, many years later in 1992 and through popular demand she then opened a second dojo in Rainham. 

Through her time as an instructor, she has trained numerous black belts, many of whom still train with her today.

Moira herself received her Great Britain badge and represented the GB at the first ever Ladies European Championships at Crystal Palace in 1982. In this debut international performance, she won a bronze medal in the under 53 kilo category - the first ladies medal won for Great Britain in Kumite. She went on to perform at European and World tournaments and picked up more trophies along the way.

She retired from international competition to raise her children, who themselves began training at the age of 7 years and reached their black belt grades. Her daughter has also represented England at European and World championships.

Following her competition days, she went into coaching and lead her students to further success, boasting English and British champions at junior and senior level. Many of these students held onto their title for 3, 4 or 5 years in a row and also gained international status.

She went on to gain her British Referee badge for both kata and kumite in the early 1990s. 

Sensei Moira Barber was awarded her 7th Dan in November 2014.


Sensei Martyn Le Breiully; 5th Dan

Chief instructor, Kaicou Kai Grays


Martyn started karate at age 7 under instructor Sensei Moira Barber. He soon realised, even at a young age, that dedication and self discipline was needed in order to succeed. That philosophy paid off, with further years of training to develop when in 1999 he achieved his 1st Dan black belt.


Focusing on competition in team kata, he won his first gold medal at the English Championships, alongside his then fellow club mate Sensei David Young. At this point, he was selected to represent England in the 2001 World Karate Championships in Athens. Further success at national level followed, with the team retaining their British champions title for three successive years, winning silver in the 4-Nations cup and an individual silver at the English Championships in 2003.


In 2004 he was given the opportunity to take over the running of the Grays club from Sensei Barber, where he has since driven new as well as existing students to success.


Having been awarded his 5th Dan in 2015 and qualifying as an English Karate Referee in 2016, he continues to progress and pass on his enthusiasm to our students.

Sensei David Young; 6th Dan

Chief instructor Kaichou Kai Hornchurch


David began karate at the age of 8 years and attained his 1st DAN black belt in 1997. This huge achievement gave him great confidence and he began to win medals in both kumite and kata.

It was at this point he also began to support Sensei Moira with the teaching at her club. This was something he enjoyed enormously and really helped with his development and understanding of techniques.   


In 2001, he took part in the adult National Championships where he came away with gold in team kata. Success in team kata continued in the following two years and led to his England badge being awarded. After a few silver medals at the British Open, the team finally won a gold in 2004. This was to be his last competition for ten years. In 2004 he also got his 3rd DAN black belt, which remains one of his greatest achievements.


David was awarded 5th DAN in 2015. It was during 2015 that he also opened his new club – Hornchurch Kaichou-Kai. His club has grown in numbers, with many now advancing with their belts and also winning medals at competitions.


Our Sampeis

Sensei Michael Frewin; 4th Dan 

"You are never too old to set a goal."

Sampei Luke Frewin; 2nd Dan

"Wearing a Black Belt doesn't mean you are invincible. It means you never gave up, pushed yourself mentally and physically and kept fighting on."


Sensei Kerry Barber; 2nd Dan

"Karate is so much more than self-defence, as valuable as that is. The life lessons that are taught along the way such as strength and determination in difficult situations are second to none."

Sampei James Frewin; 2nd Dan

"Karate is a way of life. You put all your hard work in to karate and in return you receive treasured and priceless attributes, many of which my fellow Sampei have mentioned. But one thing I truly cherish is the determination it gives me, whether it is within karate; becoming world champion or out of karate; achieving my dream job."
