Many different festivals occur throughout Tokyo. Major events include the Sannō at Hie Shrine, the Sanja at Asakusa Shrine, and the biennial Kanda Festivals. The last features a parade with elaborately decorated floats and thousands of people. Annually on the last Saturday of July, an enormous fireworks display over the Sumida River attracts over a million viewers. Once cherry blossoms bloom in spring, many residents gather in Ueno Park, Inokashira Park, and the Shinjuku Gyoen National Garden for picnics under the blossoms.
