Forty years ago today, on April 5, 1975, a series called “Goranger” premiered on the TV Asahi network in Japan. The full Japanese title of the show is “Himitsu Sentai Gorenja,” translated literally into English as “Secret Squadron FiveRangers.” It was the first in a long franchise devoted to the concept of a team of five people (usually four men and one woman) in color-coded costumes that bestow certain powers and skills on them so they can work together to defeat monstrous enemies either based on Earth or from other planets (or dimensions) who attack Japan and wreak havoc on, usually, Tokyo. Sentai is the general term for this franchise, although Super Sentai is technically the more accurate term for the seasons that began in 1979 since Super Sentai refers to a sentai series with mecha (mechanical vehicles, usually human- or animal-shaped) used by the heroes. (I’m just going to refer to the entire franchise as sentai, non-italicized, in the rest of this piece.) Sentai series are best known in the U.S. for their American version, Power Rangers, which has been on the air since 1993. (The picture on top is from “Denjiman,” the 1980 sentai season, which I’ve reviewed here on IMDB.)
Sentai shows are part of the broader Japanese genre of tokusatsu, meaning live-action special effects programs, usually in the sci-fi or fantasy genres. Famous tokusatsu programs include the Ultraman and Kamen Rider franchises and “Giant Robo” (aka “Johnny Sokko and His Flying Robot”). I covered some of these shows in Ultraman Heaven, my entry from December 15, 2014, and Classic Japanese TV from March 16, 2014.
