Bjarke Frellesvig 

3rd Dan JKA

JKA International Level D Instructor


Bjarke started karate when he was in high school in Denmark. He was so taken with it that he took a gap year between high school and university to go to Japan to train. He stayed for just over three months, with intensive training (three times day) at Hashiguchi Shinobu Sensei’s Seishinkan dojo in Kyushu.


He passed black belt (1st Dan) in 1982 and was graded 2nd Dan in 1986. By then he was studying Japanese at University and went back to Japan as an exchange graduate student for one and a half years , experiencing the teaching of some of the great JKA instructors of the time, including Asai, Osaka, Tanaka, and Yahara. 


Work and family commitments curtailed training for a while. He came to Oxford to work in the University in 1999 and was able to get in to regular training again with the Oxford University Karate Club. He was graded 3rd Dan (Sandan) in 2013 by Osaka Sensei.  


His work teaching  Japanese linguistics takes him to Japan regularly and always tries to take advantage of the opportunity to train there, with some of the best instructors in the world.
