The annual Kōtō Ward Fireworks Festival will see 6,000 fireworks going off -- making it about a third of the size of Tokyo's biggest fireworks festivals. It's still a good, colorful show though, in a nice spot -- Sunamachi Mizube Park, near the Arakawa River. Tickets All seating is reserved and costs . You won't be allowed near the venue without a ticket. Kōtō residents will get first dibs when it comes to tickets. From August 1, tickets will go on general sale (if there are any left). Where can I see the fireworks for free? There will be almost no free spots near the launch point, but if you travel farther afield, you may get lucky. Kasai Bridge is a popular viewing spot, as well as the opposite river bank near Nishi-Kasai Station. How to get there The venue is 15 minutes from Minami-Sunamachi Station.
