A Kushanku inspired drill from Rok Derencin (video)

In this video Rok Derencin shows a drill he developed – for his black belt exam – which utilises movements and principles found in Kushanku kata. I met Rok and Tomaz Stanovnik (the uke in the clip) at a seminar I taught in Germany a year or so ago. We talked a lot at the seminar and since then Tomaz and I have been in regular contact. Some of you may remember I have posted some of Tomaz’s videos too and they have been very well received.

I really like Rok’s drill and, as I’ve said many times before, I think it is a fantastic thing for our community that people are using modern technology to openly share their ideas and methods. It takes both creativity and depth of understanding to come up with such material; and it takes courage, confidence, and selflessness to openly share such information.

I hope you will support Rok – and all others who are adding to the collective knowledgebase – by sharing this drill with others in the hope that they find it valuable and that it inspires more people to put their heads above the parapet and share their own ideas.


All the best,

I like it! Many of the movements he shows are different from how we do Kusanku, but they are still familiar to me from other kata, and I like the applications. Thank you for sharing, Rok!

Thank you for sharing! I like your applications! I'm not familiar with Kushanku performed in that way, but the bunkai seems smooth, efficient and well designed to flow past any obstructions that might occur.

Well done again and keep posting your great work!

Thanks for sharing. Depth of detail and highly informative. A lot of information here to digest. 

I'm particulary interested in the arm bar at  0:13, 0:41 & 2:10 resulting elbow hyperextension/dislocation. We've been studying Naihanchi\Tekki Sandan & Wan Kan, I've been stuck on a few places and now I can see possible arm bar sequences to explore there.

Hello everyone,

thank you for all your kind words, I am glad you like the drill as I (and Tomaž) have spent quite some time working on it. As far as the Kusanku goes, it is (as far as I know) the variation from Oyata. 

I'm very happy that you can find it useful for your training and drills and that it sparked new ideas  :)

Iain, thank you again for posting the video and your words of encouragement.
