I received the email below from Jiro Nakazono Sensei - who asked for his comment to be added to the article.
Dear Ellis sensei,
I read your article in recollection of my father, Masahilo Nakazono, and it brought back all of my memories of Aikido in Europe in the 1960s' which was in its Golden Age.
Thank you, from the bottom of my heart, for this tribute; no one can do this better than a person who has actually pioneered the Martial Art in Europe, then filled with the many and real physical challenges. You were my heroes then, and you still are today in my heart that remembers the Aikido in its birthing period in Europe. You made it golden with all of these great teachers.
