The Seiun Award (星雲賞, Seiunshō) is a Japanese speculative fiction award given each year for the best science fiction works and achievements during the previous calendar year. Organized and overseen by the Science Fiction Fan Groups' Association of Nippon (SFFAN; 日本SFファングループ連合会議, Nihon SF Fan Group Rengō Kaigi), the awards are given at the annual Japan Science Fiction Convention.[1] It is the oldest SF award in Japan, being given since the 9th Japan Science Fiction Convention in 1970.
"Seiun", the Japanese word for "nebula", was taken from the first professional science fiction magazine in Japan, which had a short run in 1954.[2] The award is not related to the American Nebula Award.
It is similar to the Hugo Award, which is presented by the members of the World Science Fiction Society, in that all of the members of the presenting convention are eligible to participate in the selection process, though it is not a one-on-one comparison as the Hugo Awards are open to works from anywhere in any language, while the Seiun is implicitly limited to works released in Japan and written in or translated to Japanese.
