The commonality with your aikido and kinomichi is visible in your physical waza AND in the writing and philosophical, spiritual emphasis.
Your sensei didn't adopt the name change?
Never read his thoughts though. My teacher adopted a name for his Aikido and went independent too. He called it Zen Shin Kan Aikido. Based in North Watford. Still going today, as a private dojo.
He has a few students who went on to be teachers in various parts of the world. My co-teacher and friend recently visited him and helped him through an illness. All good.
