Kudo is a contemporary martial art that integrates elements of full-contact punching, kicking, throwing, ground fighting, and submissions. It serves as a lifelong discipline, a comprehensive system for youth development, as well as a practical method of self-defense and health promotion for adults.

Kudo emphasizes the principles of 'Reigi'—respect and etiquette—in line with its traditional Budo origins from Japan. As a modern martial art, Kudo has established an international presence, with practitioners and schools in over 50 countries worldwide.
