Aotake dōjō
In April 2020, Yaoki Dōjō was bestowed on Stephanie Dunham Sensei. Because of the pandemic, Yaoki Dōjō was later opened in September of that year. Having accepted a student, Stephanie Sensei began teaching Ninpo Taijutsu and Japanese Jujutsu. When the organization connected to Yaoki Dōjō closed, Stephanie Sensei sought out another organization to join.
In August of 2023, Stephanie sought entry into the Shisenkan International Kobudo Federation and was accepted by Ron Kosen Sensei as his student. Ron Kosen Sensei awarded Stephanie a new dōjō name, Aotake (Blue/green bamboo) Dōjō as an official dōjō of the Shisenkan International Kobudo Federation. Stephanie is excited about the future of Aotake Dōjō and welcomes anyone who wants to grow as a person to join her and her students in their new endeavors!
