notably in Japan by Expo '70. Komatsu's Nihon Chinbotsu (aka Japan Sinks, 1973) was a best-seller. Uchū Senkan Yamato (aka Space Battleship Yamato), a work of anime placed in a science fiction setting, was aired, and Star Wars was screened in Japan in the late 1970s. The change in the nature of the science fiction genre in Japan that resulted from these events is often called "Infiltration and Diffusion" (浸透と拡散 Shintō to Kakusan). At this time, Hanmura's series and Hirai's Wolf Guy series became prototypes of later Japanese light novels through the works of Hideyuki Kikuchi, Baku Yumemakura, and Haruka Takachiho. In addition, new science fiction magazines such as Kisō Tengai (奇想天外), SF Adventure (SFアドベンチャー) and SF Hōseki (SF宝石) were founded. A number of notable authors debuted in either SF Magazine or one of these new publications: Akira Hori, Jun'ya Yokota, Koji Tanaka, Masaki Yamada, Musashi Kanbe, Azusa Noa, Chōhei Kanbayashi, Kōshū Tani, Mariko Ohara, Ko Hiura, Hitoshi Kusakami, Motoko Arai, Baku Yumemakura, Yoshiki Tanaka and Hiroe Suga. In the 1980s, the audio-visual side of the Japanese science fiction genre continued to develop. Hayao Miyazaki's Kaze no Tani no Naushika (a.k.a. Nausicaä of the Valley of the Wind) and Mamoru Oshi's Urusei Yatsura 2: Beautiful Dreamer were first screened. On TV, real robot anime series, starting with Mobile Suit Gundam, were aired, and the science fiction artist group Studio Nue joined the staff of The Super Dimension Fortress Macross. Animators Hideaki Anno, Yoshiyuki Sadamoto, Takami Akai, and Shinji Higuchi, who had attracted attention by creating anime that had been exhibited at Daicon III and Daicon IV, established Studio Gainax. Wintery age Literary science fiction magazines started to disappear in the late 1980s when public attention increasingly switched to audio-visual media. The Hayakawa science fiction contest was also discontinued, removing a major outlet for the work of many writers. A number of science fiction and space opera writers, including Hosuke Nojiri, Hiroshi Yamamoto, Ryuji Kasamine, and Yuichi Sasamoto, began writing "light novel" genre paperback science fiction and fantasy novels, which are primarily marketed to teenagers. This period, during which literary science fiction declined, has been labeled "the Wintery Age" (冬の時代 Fuyu no Jidai). In the mainstream of science fiction, Yoshiki Tanaka published Ginga Eiyu Densetsu (a.k.a. Legend of the Galactic Heroes) series. The boundary between science fiction novels and light novels was blurred in the 1990s. Although Hiroyuki Morioka's Seikai no
