National Scout jamboree (Boy Scouts of America) National Scout jamboree (Boy Scouts of America) The national Scout jamboree is a gathering, or jamboree, of thousands of members of the Boy Scouts of America, usually held every four years and organized by the National Council of the Boy Scouts of America. Referred to as "the Jamboree", "Jambo", or NSJ, Scouts from all over the nation and world have the opportunity to attend. They are considered to be one of several unique experiences that the Boy Scouts of America offers. The first jamboree was scheduled to be held in 1935 in Washington, D.C. to celebrate the 25th anniversary of
International Boy Scouts, Troop 1 Scout association's readmission to the world Scout organization. John Mittwer, a founding member of the IBS as a boy, and an active IBS Scouter, was also serving on both the Board of the Kanagawa Council of the Boy Scouts of Japan and as a District Commissioner for the Boy Scouts of America's Far East Council. Helping to revive postwar Scouting, he was a key organizer of the event that again brought groups from the IBS, the BSJ, and the BSA Far East Council together for an "international" camp held in Yokohama at Sankeien, the private garden of Mr. Hara.
