As a 7th dan who was promoted by my teacher and husband who was a 4th dan when we left Kokikai, I can tell you that my rank is legitimate to me. I really don't care what anyone thinks. I know how much I am on the mat and I know what aikido means to Ron and to me.
If people want to know our pedigree we are very open about it. Certificates don't make a person a good teacher or a good student. An open welcoming dojo where students can learn how to defend themselves and become more aware is our goal. And of course, being able to train till we are dead.
