Akakage is a ninja who wears a red-and-black costume and a stylized red mask. He was created by Japanese manga artist Mitsuteru Yokoyama. His adventures are set in Feudal Japan, where Akakage and his ninja sidekicks, Aokage (青影, Blue Shadow, a little boy) and Shirokage (白影, White Shadow, an old man) fight evil warlords. The ninjas use their superhuman fighting powers and high-tech gadgets to defeat these warlords in a genre referred to as daikaiju, in which protagonists combat a range of humanoid monsters.
Kamen no Ninja Akakage (仮面の忍者 赤影, Masked Ninja Akakage), was produced by Toei Company Ltd., and aired on KTV and Fuji TV from April 5, 1967, to March 27, 1968, with a total of 52 episodes (divided into four segments). Akakage was played by Yuzaburo Sakaguchi, Aokage was played by Yoshinobu Kaneko (younger brother of fellow child actor Mitsunobu Kaneko of Akuma-kun and Giant Robo fame) and Shirokage was played by Fuyukichi Maki.
This was Toei's first color tokusatsu superhero show and Japan's first color live-action ninja TV series. Aokage's footage from the series was used to create several Watari films with the titles like The Magic Sword of Watari (not to be confused with the unrelated 1966 film Watari, Ninja Boy).
The story is set in the late sixteenth century, when Japan was in the midst of a long period of civil wars. While some seek to unite Japan in order to bring peace, there are others who encourage conflict in order to bring more power to themselves. Akakage, Aokage and Shirokage are all good ninjas working for those who seek peace and unity and battling against evil ninjas and their daikaiju (giant monsters).
