The 13th World Scout Jamboree (第13回世界スカウトジャンボリー, dai-jūsan-kai sekai sukauto jamborii) was held August 2 to 10, 1971, on Asagiri Heights on the western side of Mount Fuji, in Fujinomiya, Japan, approximately 80 miles southwest of Tokyo. The Jamboree was interrupted by Typhoon Olive in which 16,000 of the participating Scouts were evacuated to shelters in the countryside for 48 hours. The site itself covered an area of grassy sandbank of about 4 km2, sloping gently from east to west. The Jamboree Camp headquarters, Subcamp #11 Chūō, in the center of the site, was roughly rectangular in shape.
