I was born in 1985 in Germany. I started my martial arts training in 2005 with German Jūjutsu and traveled to Okinawa in 2008 for the first time. Since then, I have traveled annually to Okinawa or Japan. I spent hours in specific libraries to get a better understanding of Japanese martial arts history.
After years of private research, I think it is time to share some of my findings.
