Tsu shin gen is a offshot from kyokushin created by David Cook (born in the england but like many other english kyokushin profiles living in sweden since the 70/80ies). Cook Left Kyokushin in the late 80ies/early 90ies, went to ashihara (and was a leading figure in Ashihara international in europe, and cooperated close with Bluming until a few years ago when they had a falling out.
Like Daido juku it has become very MMA inspired, and allows a lot of grappling in competitions.
These are trailers for the AFS (Allround Fighting System) open event held regularly by tsu shin gen in sweden.
