is a programming block on the Japanese television network TV Asahi featuring new episodes of tokusatsu television series from the Super Sentai, Kamen Rider and Metal Heroes. Both series have decades of history and have been intertwined in the public imagination for some time, not least of all because the driving creative force behind both was manga artist Shotaro Ishinomori and both were produced by the same production company, Toei Company; however, they did not air together until 2000 with Kamen Rider Kuuga and Kyuukyuu Sentai GoGoFive (which was quickly replaced by Mirai Sentai Timeranger 2 weeks later), though at the time they were not acknowledged together. Super Hero Time airs every Sunday morning, from 9:00 to 10:00 JST. The block is shown all over Japan via the All-Nippon News Network. Though, in other prefectures, one or both shows can be seen on other stations which are not affiliated with ANN. History Starting in the late 1960s, the hour was originally meant for educational children's programs. Over the years the hour began including henshin (transforming) hero programs, one of the first being . On October 4, 1987, Toei's Choujinki Metalder was moved from a Monday evening 19:00 JST time slot to a Sunday morning 9:00 JST time slot, followed by a move of Kidou Keiji Jiban to 8:00 JST Sunday morning on April 2, 1989. Similarly, on April 6, 1997, Denji Sentai Megaranger was moved from a Friday evening 17:00 JST time slot to the Sunday morning 7:30 JST time slot, pairing it up with B-Robo Kabutack. The Super Sentai Series programs would continue to air at 7:30 JST after the Metal Hero Series ended and Moero!! Robocon aired in its slot on January 31, 1999, and was followed by the premiere of Kamen Rider Kuuga on January 30, 2000. Although a Super Sentai Series and a Kamen Rider Series aired side-by-side, the Super Hero Time branding of the shows did not begin until the Autumn 2003 broadcast season (known as until the 2005 broadcast season). As part of the block, actors from the programs often interact with each other to promote each other's shows, films, and perform skits. Satoru Akashi (Mitsuomi Takahashi) and Souji Tendou (Hiro Mizushima) talked about each other's universes, and Master Xia Fu (voiced by Ichirō Nagai) often showed up on the Den-Liner to talk with the Imagin and Ryotaro Nogami (Takeru Satoh) in cartoonish caricatures.
