The May Seminar

CKF International Spring Jodo and Iaido Seminar and Grading

34th Annual - May 17-20, 2024

Originally the Sei Do Kai Spring Iaido Seminar, when I say "May" this is what I mean because it pretty much takes over my life for that month.

Christopher Mansfield Sensei

Ohmi Goyo Sensei


Kurogo Genji Sensei

Fujisaki Koro Sensei

The University Hostel Services has provided the following information.

The Jodo instruction this year will focus on Koryu. There will be practice on the Sunday morning to prepare for the grading that afternoon.

The CKF plans to hold a Jodo grading up to 3rd dan at the University of Guelph on May 19 at 1pm. See here for details.

Further details will be provided as they become available.

The long-time discount we have enjoyed at the University of Guelph is going to be discontinued. Our discount will be decreased by 25% each year for the next 4 years until we are paying the full price. Registrations will need to increase to keep us from losing money, and I estimate that an increase of $20 per person will be so that we don't lose money, but we'll see about future years.

** For those who've registered for Sei Do Kai events so many times it's a habit, please note the change in our Payment Methods last year. **
