The National Cherry Blossom Festival is a spring celebration in Washington, D.C., commemorating the March 27, 1912, gift of Japanese cherry trees from Mayor Yukio Ozaki of Tokyo City to the city of Washington. Mayor Ozaki donated the trees in an effort to enhance the growing friendship between the United States and Japan and also celebrate the continued close relationship between the two nations. Giant colorful helium balloons, elaborate floats, the energy-filled Parade, marching bands from across the country and a grand spectacle of music and showmanship seen only once a year are parts of the Festival.
