I would like to express my heartfelt thanks to Ikeda Jūshū 池田重秀, the 4th Sōke of Tō’on-ryū. Without karate training, it is almost impossible to write an academic paper on a karate figure, a karate kata, or even a karate anecdote. In this process, it is not only important to consult written works but also to speak with karateka within a karate lineage. Without taking these steps, the expected research results cannot be achieved.

The Jion kata was already my favorite kata during my Shōtōkan days, and I still focus on it. This led to the decision that Ikeda Sensei showed me „Yabu no Jion,“ even though this kata was planned for a later visit. Since I was already familiar with a version of Jion, I was able to quickly adapt Yabus version of Jion – of course, there are still many things that need Ikeda Sensei’s corrections.
I am deeply grateful to Ikeda Sensei for teaching me „Yabu no Jion“ and for allowing us to include two photos with him in the article. A special thanks also goes to my wife, who took the fantastic pictures.
A small note about the photos: we chose identical movements that were also performed by Funakoshi Gichin (1925) and Hanashiro Chōmo (1938).
Ikeda senseis words are as follows:
Yannick, a member of Tō’on-ryū, published his research findings on Jion in [Gekkan] Hiden. I consider the research content to be excellent.
