 Takeshi Ikeda handing the Seiun Award prize toTakayuki Tatsumi, at the Hugo Awards Ceremony 2017 at Worldcon in Helsinki | |
| Awarded for | Science fiction works and achievements of previous year |
| Country | Japan |
| First award | 1970; 55 years ago (1970) |
| Website | www.sf-fan.gr.jp/awards/index.html |
TheSeiun Award (星雲賞,Seiunshō) is a Japanesespeculative 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 annualJapan 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 AmericanNebula Award.
It is similar to theHugo Award, which is presented by the members of theWorld 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.
A professional work or achievement which appeared for the first time in the previous calendar year may be considered eligible. The eligibility of magazines is determined via nominal publication date, which often tend to be a month or two ahead of the actual date due to Japanese publication customs.
There are no written rules about word count for literary fiction categories, so that the decision of eligibility in that regard is left up to the voters.
Usually in spring, SFFAN issues reference nominee lists for reference in each category, which is chosen by the preliminary vote of their member groups. However, voters can cast their ballots for any eligible works outside of the list in the final ballot.
With consideration for voters' availability, a work which appears in a magazine (such as a part of serialized works or short story) or released as audio-visual media (such as a TV show or film) but wasn't chosen for the reference nominee lists may be eligible again if published as a book or released in any other media format.[1]
There are effectively no official English names for categories, so they vary depending on translators. For example, "Long Work" may be written as "Long Story", "Long Form", or "Novel"; "Short Story" may be referred to as "Short Form" and so on.
| Current categories | Year started | Current description |
|---|---|---|
| Best Japanese Long Work (日本長編,Nihon Chōhen) | 1970 | Science fiction novels and stories which appear or are translated for the first time during the eligible year. Serialized works on magazines may be eligible when they are finished; other works may be eligible when they get published as a book. A multi-volume work may also be eligible as a whole series when it concludes. |
| Best Japanese Short Story (日本短編,Nihon Tanpen) | ||
| Best Translated Long Work (海外長編,Kaigai Chōhen) | ||
| Best Translated Short Story (海外短編,Kaigai Tanpen) | ||

| Best Comic (コミック,Comic) | 1978 | Manga. Serial works may be nominated upon completion as is the case with Long Works. |
| Best Artist (アート,Art) | Artists with notable achievements. | |
| Best Nonfiction (ノンフィクション,Nonfiction) | 1985 | Nonfiction works about SF such as studies and critiques, including translated ones. Serial nonfiction can be nominated upon completion as is the case with Long Works. |
