Sumida River Fireworks Festival
On the last Saturday of July, Asakusa's streets fill with crowds in yukata. Two venues on the Sumida River fire in relay about twenty thousand shells, as nearly a million people watch from the banks, rooftops and bridges, the fireworks framed alongside Tokyo Skytree. A summer event born in the Edo period, it is one of Japan's oldest fireworks festivals and the most classic image of a Tokyo summer.
