Sensei Iha, Mark and Roberto

Beikoku Shidokan National Training Seminar


Seikichi Iha, Hanshi, 10th Dan
Seikichi Iha, Hanshi, 10th Da

This year’s Beikoku Shidokan National Training Seminar will be held July 31 and August 1. Normally, NTS is held in Lansing, Michigan. This year Sensei Seikichi Iha, 10th Dan, will hold a virtual seminar so you can attend from your home! Sensei Masatoshi Miyazato, 10th Dan, from Argentina will also attend! Each day will have one 2-hour long training session.

Just imagine, you get to train with two 10th Degree Karate Masters while attending only one event and you don’t even have to leave town!

We may set up so you can participate from the dojo so we can correct or improve your techniques giving you the maximum training benefit of this one of a kind event.


Please contact me for more details as they become available.
