Martial arts

I have been practicing martial arts since 1986, currently I run our Hakuzan dojo, where I teach Japanese swordsmanship of the Happó ryu style. We organize tournaments in Gekiken freestyle fighting and tameshigiri and cooperate on projects and with various personalities and participate in public exhibitions (enbu)

More details in - Profile.

In 2010 I have established Hakuzan Dojo (Toyama Ryu, Happo Ryu) in Prague and I still run it today.

In June 2012 in Prague, I organized the first Tameshigiri taikai - Japanese sword cutting competition. This became an every-year tradition of our Hakuzan Dojo Prague. In 2014, the first Enbu Taikai in shuriken jutsu. In 2016 and 2017, I happened to be the winner of shuriken jutsu Taikai in Prague.

For many years I have been theoretically and practically also interested in European fencing. I am an honorary member of the oldest Czech fencing club Riegel and the initiator of the national fencing style Czech saber. In 2020 I led a saber cutting workshop at the most prominent regular event with saber fencing in the Czech Republic called "Saber Slash".

In 2017, 2018, 2019 and 2022, I organized seminars with Master Matsuba Ichiro (menkyō kaiden Jiki Shinkage-ryu, 7th Dan Aikido), who is with his artistic name Kagemasa also a swordsmith with the highest master degree - Mukansa.

In 2018 I cooperated with the Veles stunts agency on organizing a workshop of Tetsuro Shimaguchi, Kengido master of the Kengidó style and among others the choreographer of the fighting scenes of Tarantino's Kill Bill. In 2019, I repeatedly performed with him at various exhibitions (enbu).

In 2018 I have organized the 1st annual "Japanese evening in Smíchov", presenting Japanese traditional culture and martial arts.

Since 2022, I am organizing in cooperation with the Strahov Brewery "Hanami" - festival of Japanese culture in the Strahov Monastery. This festival with many thousands of spectators aspires to become one of the largest events focused on Japanese culture in Prague and it also includes martial arts demonstrations of many friendly dojos and Taikai tournaments.



Our dojo participates (including Tameshigiri) in public exhibitions at cultural events mainly focused on Japan.


Basic info

For many years now I have been devoted to the Japanese art of throwing blades called "shuriken jutsu". I have won the Shuriden Jutsu Taikai several times (always 1st place). In addition to the traditional bo shuriken (kugigata, futabari gata), after meeting with the five-time knife throwing world champion Adam Čeladín, I began to study his unique no spin throwing method and to apply it to various Japanese blade weapons.


It is a competition in "shihoken shuriken" (four-pointed star) throwing which is easy for untrained individuals. We organize shuriken taikai at the regular Japanese culture festival "Advík".

Personal development

I plan to work hard on my skills so that one day I could aim for all-Japan shuriken jutsu competition. That's why I practice the art of shuriken jutsu as well as the art of the Japanese sword every day.


A tournament in the Gekiken discipline which we organize is also visited by international participants. During the tournament swordsmen with various previous specialization backgrounds (kendo, iaido, hema, historical fencing...) can compete and test and apply their previous experience in practice. Technical grades can be obtained by winning the tournament. Gekiken Taikai is often held at the same time as the Tameshigiri Taikai.

My activities

I have designed Gekiken as part of Happó ryu in a way that it would be possible to verify techniques in real time and space, and so the understanding of the path of the sword would became more complex and so also the rules of the match reflect that. Those are based on the a martial arts requirement of surviving rather than scoring a point a fraction of a second earlier as often presented in sport fencing. In such a situation, an aiuchi (simultaneous hit) would be inevitable, which would inevitably lead to the death of both combatants. That is why Gekiken rules punish aiuchi.
