Advice on Hombu dojo etiquette
I'll be visiting Japan in April, and hope to get in a few classes at the Hombu dojo in Tokyo, as well as various others around the country. In the cases of the smaller dojos I've contacted them directly to introduce myself. What is the correct etiquette for the Hombu? The website gives some general guidelines about signing in and payment etc, but should one make oneself known to the sensei once on the mat, or just dive in?
As a relative newcomer (5th kyu), would Doshu's classes be way out of my league? Any other tips?
Be gentle, this is my first post.
All the best.
