Dojo Kun - literal translation means "training hall rules". There are five main rules that serve as guiding principles for all who train in the dojo. Although they are usually listed in a set order, no one rule is more important than any other. To emphasise this all five are prefixed with hitotsu and end with koto, which together means "one point".
One Point! Refrain from Violent Behaviour
Hitotsu! Kekki no yu o imashimuru koto
