Each year the Nihon SF Taikai attracts between 1,000 and 1,500 science fiction fans. Events at the convention include panel discussions, lectures, readings, screenings, parties, games, concerts, and a dealing room for the sale of rare books, magazines, and other items related to science fiction.

A number of prizes are awarded at the convention, most notably the Seiun Award for the best science fiction of the year as voted by attendees of the convention.

Outside Japan, the Nihon SF Taikai is most famous for the animation for the opening ceremonies of Daicon III and IV Opening Animations, which was produced by the animators that later became Gainax. The DAICON IV opening video features a girl in a Playboy Bunny suit with cameos from many science fiction films and stories.
