Sensei Yoshinobu Ohta 7th Dan – Chief Instructor

Sensei OhtaOur Chief Instructor is Yoshinobu Ohta, 7th Dan. Ohta Sensei is a graduate of Takushoku University and has also attended the famous Instructors Classes at JKA Headquarters in Japan. Takushoku University in Japan has a tremendous reputation as one of Japan’s strongest Karate clubs and the club coach Ishikawa Sensei encouraged Sensei Ohta to continue studying karate. Many of the JKA’s top sensei’s including Masters Nakayama and Enoeda had previously graduated from Takushoku.

After leaving university he decided to continue with Karate at the JKA. Sensei Tsuyama chief instructor of the Takushoku University Karate Club encouraged Sensei Ohta to train at the highly prestigious JKA instructors classes where Sensei Ohta soon found himself training alongside such respected names as Sensei’s Shoji, Asai, Abe, Tanaka, Osaka, Kagawa and Yahara. It was also common practice at this time for Sensei Nakayama to teach and assist during classes.

In 1982, Sensei Ohta was selected by Sensei Enoeda to come to England and become his assistant. From 1982-2003 Ohta Sensei was the assistant to Keinosuke Enoeda, 9th Dan. In the following twenty years Sensei Ohta had build up a reputation as a very popular and technically brilliant senior instructor in his own right. It was during this time he gained an international reputation for being one of the most technically skilled JKA instructors. In 2003, following the death of his mentor Sensei Enoeda, Sensei Ohta was appointed as the chief instructor of JKA England and has built up the association from strength to strength.

In April 2010 Sensei Ohta passed the examination for 7th Dan in front of the JKA’s most senior technical committee at the JKA HQ Honbu Dojo in Tokyo.

Simon Marchant-Jones 3rd Dan – Treasurer

Simon Marchant-Jones first studied karate at Leeds University in 1974; like many new studentsimon-marchant-joness at that time, he had seen Bruce Lee and had been inspired to start a martial art. Gradings at Leeds were given by Sensei Enoeda so when, in 1976, he moved to London he joined the renowned Marshall Street dojo. Simon was at Marshall Street when Sensei Ohta arrived in 1982, but pressure of work and a young family took priority so Simon took a sabbatical until 1999.

In 1999, aged 45, he re-commenced training and gained his first black belt in 2003 under Sensei Ohta, and passed third dan in 2011. A Chartered Accountant by profession, Simon teaches at the Harpenden JKA Karate club. He is a regular at Sensei Ohta’s Oasis dojo and can be seen at most JKAE events where his specialisation is taking money and stamping licences.

Glyn Morgan 5th Dan – Child Protection and Discipline Officer

Glyn started karate back in 1974 when he saw a small advert for “learn karate – beginners wantglyn-morganed”, and went along to a small club on the Isle of Portland in Dorset. Gradings back then were held over the weekend for 3 days with Sensei Eneoda, and Sensei Tomita (even taking all his grading with Sensei Eneoda). Even as a white belt, he remembers them as unforgettable experiences and so has continued training ever since.

A keen believer in attending a many courses as possible, he focuses on continually improving his own karate and those of his students in the Purbeck & Wareham club for which he is an instructor. As well as a regular face at courses and a referee at competitions, often giving out medals, Glyn was also a member of the Coastguard Service for 25 years involved in search and rescue and has collected several medals himself for life saving.

Lester Wellington 4th Dan – Licensing and Membership Officer


Lester started karate back in 1981 at the Budokwai dojo in Chelsea with Sensei Caesar Andrews taking his first few gradings under Sensei Tomita. After a fairly long break due to the pressures of work, it was his son Christopher who persuaded him to restart and not before long, he had gained his Shodan in 1999. He is currently a C Licence Examiner; C Licence Instructor and C Licence Referee.

A former Metropolitan Police officer spanning 30 year career, Lester taught self defence to other police officers for over 10 years. It had always been Lester’s ambition to run his own club and in 1999 opened Tairyoku SKC and has grown in students ever since then.

A firm supporter of JKAEngland, Lester is a regular feature at JKAE courses and competitions. Lester has his hands full running his club but still manages to find time to enjoy his family and his favourite pastime of Geocaching.
