Glossary of Judo terminology
"Budokan" refers to a facility in which Japan's traditional martial arts such as Judo, Kendo, and Kyudo are performed. In addition to the well-known Nippon Budokan, Tokyo Metropolitan Police Budokan, Saitama Prefecture Budokan, there are also other Budokan in various other Prefectures.
The Nippon Budokan was built the year of the Tokyo Olympiad (1964) for the purpose of promoting the essence of Japan's martial arts-uprightness and peace-to the multitudes, and to contribute to the development of the Japanese people and to world peace. The building's structure forms an octagon with an area of 8,132m2, with 2 basement floors and 3 upper floors.
