Nice post!!!! I feel empathy with your desire to learn Ninjutsu, your perseverance and your feeling now, as a Shihan.
Let me paraphrase your words:
“The reason I study ninjutsu — for me it is not a hobby or a fad. It is a beautiful life long journey of learning and teaching.
That what I feel too. I cannot teach yet, but I hope I can soon.
Thanks for your text. Very inspiring!!!!
Domo arigatou gozaimasu!
