Super Sentai

Super Sentai (スーパー戦隊, Sūpā Sentai) is the name given to the long running Japanese "superhero team" genre of shows produced by Toei Company Ltd. and Bandai, and aired by TV Asahi ("Super" refers to their use of mecha, and "sentai" is the Japanese word for "task force" or, literally, "fighting squadron" and was also a term used for Japanese squadrons in WWII). The shows are of the tokusatsu genre, featuring live action characters and colorful special effects, and are aimed mainly at families. This series is one of the most prominent tokusatsu productions in Japan, alongside the Ultra Series, the Kamen Rider, and the Metal Heroes series. (Wikipedia)
