Renshusei from Woltersdorf, Germany

February 16th-20th, 2026 Renshusei: Erik, Robin and Tino.

Three karateka from Woltersdorf, Germany, came for training as 練習生 (Renshusei). Robin Zehbe (Godan), Tino Weichert (Sandan) and Erik Lewerenz (Shodan) from Nikko Dojo: https://www.nikko-dojo.de/

They diligently trained for two hours every day for a total of five days. Also, on one day we also did an additional two-hour training.


The focus of my teaching was on the fine details of Budo Karate. In particular, the correct use of energy and critical body mechanics; furthermore, ‘bujutsu no maai’.

I will not specifically outline the trainings as this knowledge is for them to share.


However, what I will say is that I was impressed by their enthusiasm and efforts over the days they were here as (Renshusei).


It was also great to see them improve their Kihon, Kata and Kumite as the sessions progressed.

In addition to time in the dojo, we also had a lot of good times. A big 'OSU' to Robin, Tino and Erik.
