Japanese television science fictionJapan has a long history of producing science fiction series for TV. Some of the most famous are anime such as Osamu Tezuka's Astro Boy, the Super Robots such as Mitsuteru Yokoyama's Tetsujin 28-go (Gigantor) and Go Nagai's Mazinger Z, and the Real Robots such as Yoshiyuki Tomino's Gundam series and Shōji Kawamori's Macross series.
Other primary aspects of Japanese science fiction TV are the superhero tokusatsu (a term literally meaning special effects) series, pioneered by programs such as Moonlight Mask and Planet Prince. The suitmation technique has been used in long running franchises include Eiji Tsuburaya's Ultra Series, Shotaro Ishinomori's Kamen Rider Series, and the Super Sentai Series.
In addition, several dramas utilize science fiction elements as framing devices, but are not labeled as "tokusatsu" as they do not utilize actors in full body suits and other special effects.
