A generous amount of "Windaria"-related merchandise has been marketed in Japan since the movie's 1986 debut. Fujikawa's "Douwa Meita Senshi Windaria" "bunkobon" was published by Kadokawa Shoten during March 1986. Shortly after the premiere of "Windaria", several official guide books were released, one ("Settei: Windaria") containing Idol's sketches, storyboards, and promotional materials. A special "omake" was published on August 25, 1986, as part of Kadokawa's "Mediamix Special" imprint. Inomata's 1988 art book "Gatsu no Koe Hoshi no Yume" contains some of her illustrations from the film. Arai's album "Natsukashii Mirai", containing both the film's opening and ending themes, was released by Victor on October 21, 1986. Arai later re-recorded ""Utsukushii Hoshi"" for her 2005 album "Sora no Uta" due to her dissatisfaction with the first version of the song. The film's original soundtrack was released by Victor on both LP and CD on July 21, 1986, and CD was reprinted on March 24, 1994. It was reissued on June 23, 1999 alongside the soundtrack to "Birth", another anime by Kaname. Finally, a 2008 Nintendo DS video game based on the movie was developed by Compile Heart under the name and released in Japan.
