Re: What exactly is an independent dojo?
My "blue book" is a passport-like booklet from Aikikai Hombu. It is inscribed "Aikikai International Yudansha Book" on the front and incorporates my Aikikai membership number, my Aikikai Foundation number, and my rank registration number. Mine is signed by Kobayashi Shihan and chopped by Doshu. I also received a membership card from the Aikikai Foundation at the same time.
