A small shrine, especially in an aikido,
generally located the the front of the dojo, and often housing a
picture of the founder, or some calligraphy.
Here at Aikido Academy of Nebraska, you will not
find a Kamiza. Sensei is of the belief, that religion is a
personal choice and worshiping of a shrine in a Dojo is not
appropriate in his school.
Never! The instructor must always be addressed as Sensei or
Paden Sensei. Any other name is not appropriate and even
Sensei Roy or Sensei Paden is considered disrespectful.
It is like the notation of MD after a doctors name...Like:
Mike Smith M.D. You would pronounce it "Mike Smith 'M.D.' "
