Development of Budo was based on School Education. Since 1931 Budo had been selected as an essential subject to schooling as well as Physical Education. However Budo was rather stagnant for a while due to the war. In 1950 Judo renewed interest in martial arts and was considered absolutely spiritual sports. Judo, Kendo and Sumo has settled as "Kakugi" according to the lawful teaching guidance. The term of Kakugi has been called Budo since 1989. The Tokyo Olympics had an important influence upon Budo, because during the Olympics people from all areas of life including politics, economy and government in Japan became involved in Budo. For the first time they considered that Budo was necessary heritage to be preserved, inherited and developed. We need to learn from Budo. Because modern sport cares only about winning whereas Budo regards relationships among people as more important. The aim of Budo is contribution to World peace. It is time to put our efforts together to make it happen.
