The rules of Kirigakure are brutally enforced by the higher ranking ninja's of the village, and in special cases even the Mizukage himself.

1. Kirigakure follows an arm for an arm/eye for an eye rule.

2. Do not attack foreign ninja unless they show open hostility.

3. Respect those above your rank, even if its a chuunin to an academy student. The punishment for disrespecting a jounin is the loss of an eye. The kage, however doesn't really care.

4. If you leave the village without permission you will be considered a missing nin immediately and you will be hunted down before you can get out of the country.
