Taking advantage of a serendipitous schedule clash, Itabashi's annual fireworks display takes place at the same time as the one in Toda City (Saitama prefecture), just across the Arakawa River. You can expect a combined 13,000 shells of fireworks at this 90-minute event, including an enormous star mine and the spectacular ‘Niagara Falls’, a 700-metre chain of explosions that always draws the biggest cheers of the night. As a treat this year, there will be Pokémon-themed fireworks, too.
While the event is free, you might want to secure a paid seat for the best views. These reserved seats range from ¥4,500 to ¥6,000 for single tickets and ¥18,000 to ¥36,000 for groups of four to eight people. You can make your bookings online.
