Dojo Etiquette
In Aikido, worldwide, we use Japanese customs. To be welcome in dojos everywhere you travel and wish to train (and to give no offense) you need to:
Bowing: We bow to show respect. It is generally equivalent to shaking-hands,
except that it is also used to show respect for our predecessors and tradition.
Also, in the context of the dojo, the bow is a ritual mnemonic action
by which we remind ourselves to be centered, aware and present with the training
experience. Standing bow is rei, bow seated in seiza is zarei.
When to bow:
Ways to say "Thank you": (less formal) Domo, Arigato, Domo arigato, Arigato gozaimasu, Arigato gozaimashita, Domo arigato gozaimashita (most formal).
Forms of address: Learn and use traditional, conventional, Japanese terms of address in the dojo. Within our dojo: on the mat, address and refer to dan-level instructor as Sensei (or 'last-name Sensei'); elsewhere first names may be appropriate. Be aware that in some schools the term Sensei is reserved for senior teachers and there regular instructors are addressed by last or even first names. An alternative term of address less exalted than Sensei is Sempai. Other students may be addressed by last name followed by 'san', or first names. When visiting elsewhere, assume a more formal level of address for instructors unless and until invited to be less formal.
Joining Class Late?
It is customary to step onto the mat and wait in seiza to be recognized
by the instructor and invited to join the class. Once so acknowledged,
if you need to warm up to safely join the class activity, it is appropriate
to do some warm-ups and ukemi before joining in.
