Bujinkan Dai-Shihan

Bujinkan 15’th Dan, Dai-Shihan

I have been training Bujinkan Budo-taijutsu since around 1983-84 (I forgot). I passed my 5’th Dan test in August 1992, 10’th Dan in 2003, and 15’th Dan in 2008. In October 2017 I received the Dai-Shihan title (the highest rank in Bujinkan) by Hatsumi Sōke.

I have been to many many seminars all around the world for my own training, and still does. I went to 16 Taikai with Hatsumi Sōke between 1988 and 2003 when he travelled around the world (plus many Daikomyousai in Japan). I have done around 50 training trips to Japan to train with Hatsumi Sōke and the Shihan since 1990. 

I teach weekly in my own dojo at Kaigozan Dōjō in Stockholm. I do seminars when asked. I have also taught many seminars in Sweden but also in Latvia, Turkey, Hungary, Germany, Holland, Finland, Australia and Estonia.

The natural mind is one that has absorbed all learning
and is free from thought of all that it has learned.
Do not see things in things that are, and do not see things that are not.
Move beyond these things and see the truth behind.
