The Kokusai Budoin, International Martial Arts Federation, is comprised of seven divisions representing the various
Japanese martial arts. These include Judo, Kendo, Karatedo, Aikido, Iaido, Nihon Jujutsu and Kobudo. Each division has

Traditional martial arts form one of the cultural properties of Japan. Depictions of warriors in combat utilizing the
classical weapons of the sword, bow and lance, as well as un-armed measures, known collectively as Jujutsu, can be
found in ancient scrolls dating from the dawn of Japanese civilization.
Japanese history features extensive periods of warfare, and the subsequent development of the bakufu, military government,
which began with the Kamakura era (1192 - 1333), and ending with the Meiji restoration (1868). Throughout this period the
samurai held great influence politically and culturally, which lead to the establishment of numerous schools of martial
studies. This unique cultural heritage forms the basis of both ancient and modern Japanese martial arts practiced
throughout the world today.

realized after many years of dedicated practice. To gain proficiency in any one area requires endless study and
commitment, and it is through this very process that numerous unanticipated benefits occur. As such, traditional Japanese
martial arts constitute much more than methods of combat, rather, they comprise a means of developing discipline,
knowledge, soundness of mind and body, all of which in turn, serve to enrich other aspects of one’s life."
