The use of Red Cross and Red Crescent symbols is strictly regulated under international law, particularly the Geneva Conventions. These emblems are protected as symbols of medical and humanitarian aid, and their misuse is prohibited to maintain their neutrality and trust. Unauthorized use, including for commercial purposes, non-medical contexts, or deceptive actions, is forbidden.

Member states of the Geneva Conventions, including Japan and the United States, have incorporated these rules into domestic laws, with penalties such as fines or imprisonment for violations. Authorized use is limited to specific organizations like the International Committee of the Red Cross (ICRC) and National Red Cross or Red Crescent societies.

Even in illustrations or non-commercial designs, using these symbols can lead to legal issues. To avoid potential violations, it is recommended to use alternative designs, such as a green cross, when similar visual elements are needed. This ensures compliance with international and domestic regulations.
