Being respectful to ourselves and to each other is a vital part of karate. It is also part of the dojo kun. Here are some points on being respectful in the dojo.
Treat everyone with respect and dignity
Shoes should be removed before entering the dojo
Practice good personal hygiene
Ensure your gi is clean and washed regularly
Keep fingernails and toenails short to prevent hurting yourself or training partners
Remove jewellery or cover it up before the lesson to prevent hurting yourself or training partners
Tie long hair back
As you enter/leave, bow with both feet together
Try your best
Refrain from foul language and violence
Refer to your teacher as Sensei, never by their name alone
Using sensei as a title before or after the first/last name is also acceptable e.g. Sensei Simon or Apen-Sadler Sensei
If late, warm up if possible without interfering with the class and kneel at the edge of the dojo where the instructor can see you. You will be invited to join the class when it is safe to do so.
Never just join in a class without permission - this could be dangerous, and is also disrespectful
Help your senior grades / instructor(s)
Example - If you see a senior grade sweeping the floor before the lesson, offer to help
