As you may know, the main venue for the Tokyo Bay Fireworks Festival is located in Harumi, Chuo-ku.
↓The large site of the concrete part near the center of the map (Google map) will be the main venue (admission ticket required (see ↓ URL)).
By the way, if the Olympic and Paralympic Games are to be held in Japan in 2020, this place seems to be a candidate site for an athlete village.
