The JO Staff
Winter Weapons Workshop


with 6th degree black belt


Chief Instructor of HOSHU DOJO
Portland, OR

Tom Groendal JODO SENSEI traditional weapons

Aimed at developing and diversifying the staff JO skills of
AIKIDO practitioners familiar with AIKI-JO concepts,
this event, presented by an experienced AIKI practitioner, offers a window into
traditional combat applications of the unique, effective, and pragmatic 400-year-old weapon art called JODO.


Closely related to the principles of AIKIDO, JODO is the fun and challenging, paired KATA-based system
of defending oneself with a staff from an opponent armed with a sword.

Having lived in Nagoya, Tokyo, Osaka, and Oita, Japan for ten years, and being fluent in the Japanese language and culture,
Thomas Groendal Sensei is uniquely qualified to teach this rare and powerful martial art.

Beginners welcome.
No JODO or AIKIDO experience necessary.
No falling or rolling.


 Training weapons available for sale at the workshop.


For an optimal training experience,
this seminar will be limited to the first 22 registrants.

Yes, I’m coming! Save me a spot on the mat.
