The awards this year were again separated into nine categories: Japanese Long Story, Japanese Short Story, Translated Long Story, Translated Short Story, Media, Comic, Art, Nonfiction, and a "Free" category. Each category has between 6-9 nominees. The nominees were chosen among works that were released between January 1 and December 31, 2017.

The attendees of the 57th Japan Science Fiction Convention at "Juracon" in Gunma voted on the winners.

"Seiun Shō" literally translates to "nebula awards," but the Japan SF Con's Seiun Awards are more akin to the Hugo Awards, in that the attendees of each respective convention vote on the winners. There is another set of awards, the Science Fiction and Fantasy Writers of Japan's Nihon SF Taishō honors, that are the rough Japanese equivalent of the Science Fiction and Fantasy Writers of America's Nebula Awards. Like the Hugo Awards, the Seiun Awards honor all forms of speculative fiction — including but not limited to science fiction — and related materials.

Previous winners of the Seiun Awards include Shin Godzilla , Kochikame, Girls und Panzer, Knights of Sidonia, The World of Narue, Bodacious Space Pirates, Range Murata, Masamune Shirow, Makoto Shinkai, Full Metal Alchemist, Gundam: The Origin, 20th Century Boys, Summer Wars, Card Captor Sakura, Madoka Magica, Pacific Rim, Space Battleship Yamato 2199, Moyashimon , and more.
