On passing this Hatsumi Sensei awarded David with a special gift, a Bujinkan gold medal and a poem by Grandmaster Hatsumi which refers to the past, the present and the future of the Bujinkan. With this Soke Hatsumi had fulfilled one of his main intentions of having 1000 Shidoshi (Teacher) and with this great honour and responsibility David commits himself to teach these warrior traditions through his school "Sen Ki Dojo"(Training Hall of the 1000th Warrior Demon).
The Bury branch of Bujinkan Senki Dojo is based at Jericho Methodist Church, Elbut lane.
The classes cover Bujinkan Budo Taijutsu and are be run by Shidoshi Gavin Chadwick. Gavin has over 20 years experience in martial arts, is qualified to deliver Physical Intervention and Conflict Management and has studied a number of sport martial arts including boxing, thai boxing and karate before finding a martial art that takes its spirit from bushido (warrior way). Discovering Bujinkan Budo Taijutsu he studied the arts covered in the nine schools.
Through Bujinkan Sen Ki Dojos, Sensei David Castan, and Gavin Chadwick are committed to teaching the Samurai and Shinobi Martial Arts of Bujinkan Budo Taijutsu. Today they regularily train with high ranking instructors at International levels and also travel to Japan to gain knowledge in the Bujinkan Martial Arts with Grandmaster Dr. Masaaki Hatsumi and his Senior students. Their purpose is to bring back and preserve the historical accuracy of these traditional arts, as well as translate this living Budo (warrior path) into the modern context so that it can be easily understood and used by individuals to better themselves.
