Competitor's professions

Police officers provide by far the vast majority of the competitors, followed by teachers. The competitors, who participated in the early years of the tournament were from various professions, but the police force emerged from around 1965 and began to compete with the teachers for the championship in the 1950s. From then on police officers dominate the championships and Japanese kendo at professional level. They are Kendo personnel selected as part of the tokuren, a special unit of the riot police dedicated for doing professional kendo as a profession. The largest tokuren squads fully dedicated to kendo are the Tokyo Metropolitan Police and the prefectural police departments of Osaka, Kanagawa and Hokkaido. Kendo police officers in smaller prefectural police departments may also conduct regular police work in the riot squad more often than in the latter mentioned departments due to shortage. Teachers also provide a large group among the competitors. Most of them either teach physical education at high school level or kendo. A third significant group at the championships are students. They either qualify via the All Japan University Kendo Championship or through the prefectural qualifying. Two of the youngest winners of the championship were students with Yuya Takenouchi (now kendo police officer in the Tokyo Metropolitan Police) being the first student to win the championship in after 43 years.
