The following was posted last year by Ikeda Sensei on the Tou’on-ryu Facebook page, but I thought I would repost it here.

After Kanzaki sensei’s passing, we applied to trademark the characters “Tou’on” (東恩), and on March 3rd 2020 we were successful in registering it. We would like to express our sincere gratitude to all the people who helped us to achieve this. Now the name “Tou’on” will never disappear from Beppu and remain forever!
Comment from Kyan Morikazu
Congratulations! I feel that in this day and age it’s not only necessary to pass on technique and spirit, but also to do this. I admire what you’ve done.
