Judo Etiquette page 3

From the very first time you enter any Dojo, you are expected to show and learn the proper reishiki (etiquette or mat manners).  The western culture of Judo reishiki in some Dojo's has long disappeared from the proper way of reishiki.  There are many reasons for this: some being laziness of the instructor; many feel that it has nothing to do with the techniques of Judo, so they omit it; lack of interest on the student's part; lack of proper instruction on the instructors part.  It should be stressed to all players or Judoka from the youngest up into Sensei ranks as well.  True Judoka will want to learn all that they can, not just Nagewaza (throwing techniques) but all forms including the Japanese terms and influences as well as reishiki.
Bowing
Through very specific customs an orderly, functional and efficient method of conduct has been laid down for use in all Dojo.  One of the very first items of etiquette which the Deshi (student) must learn is when they enter or leave any Dojo, they must perform a Ritsu Rei (standing bow) in and out of the Dojo.  This Rei is not just a physical thing to do, but is also mentally done.  By this I mean that when entering the Dojo each Deshi (student) clears his or her mind of all evil and negative thoughts, and feels good about themselves with the good thoughts in mind to be a better person for what they are about to learn, or what they have learned at the Dojo before leaving.
The second time that they are required to Rei is when they are about to enter or leave the mat area.  Also at this time their minds should be clean and fresh with desire to learn and to become at ease with themselves.
The third time they Rei is before and after working out with a partner.  This is done with much respect as you are asking your training partner for the pleasure of working out with you, also you are saying I come with a clean mind, and have no intention of hurting you; in the event I or you should suffer injury, no ill feelings shall exist between us.
Entering the Dojo
When you are ready to enter the Dojo, you are expected to make a Ritsu-Rei (standing bow) at the entrance of the Dojo.  Upon entering you should face the mat area towards the Kamiza (the wall with Professor Kano's picture), when doing this ritsu rei(standing bow).  When you have donned your Judogi (if you change at the Dojo) and you are about to enter the mat area, you will again perform a ritsu rei before entering on the mat area.  After you have moved onto on the mat area you should take up the proper seiza (kneeling-seated) position in the proper place according to your belt rank.  You should never sit in a anza (cross legged) position until told to do so by the Sensei.  You should never start any taiso (warm-up exercises) or do any ukemi (falling practice) until the Sensei has formally opened the class.
Opening and Closing of Classes
Before opening or closing of any class session, all students and instructors shall take their proper positions on the mat area according to proper reishiki.  The four sides of a Dojo are very important in reishiki, for each has a specific code of ethics to follow.
