This DVD-R contains a record of a day long workshop given in March, 2011, in Dublin by German Bujinkan teacher Holger Kunzmann, focussing on the Koto Ryu school of Koppojutsu.

It features a lot of in depth and detailed guidance on the basics of this school, using the first couple of kata and variations as an introduction.

In addition, as a bonus, it also features a record of a master class on Ichimonji no Kata from the Gyokko Ryu, given by Holger the night before the workshop.
