Tiger Mask (タイガーマスク, Taigā Masuku) is a Japanese manga series written by Ikki Kajiwara and illustrated by Naoki Tsuji. The series was first published in Kodansha's Bokura Magazine from 1968 to 1971 and was later published in Weekly Shōnen Magazine from 1970 to 1971. It was later adapted into an anime series by Toei Animation which first aired on Yomiuri TV on October 2, 1969 and ended its run on September 30, 1971, airing 105 episodes. In real life, the name has been used by a succession of Japanese professional wrestling characters as a gimmick. The Tiger Mask persona is instantly recognizable by its trademark mask, designed to look like a tiger's head, as well as the combination of high flying attacks and martial arts in the ring.
In the manga and anime, Tiger Mask (whose real name was Naoto Date) was a feared heel wrestler in America who was extremely vicious in the ring. However, he became a face after returning to Japan when a young boy said that he wanted to be a villain like Tiger Mask when he grew up. The boy resided in an orphanage, the same one that Tiger Mask grew up in during his childhood. Feeling that he did not want the boy to idolize a villain, Tiger was inspired to be a heroic wrestler.
The main antagonist in the manga and anime was Tiger's Cave, a mysterious organization that trained young people to be villainous wrestlers on the condition that they gave half of their earnings to the organization. Tiger Mask was once a member of Tiger's Cave under the name "Yellow Devil", but no longer wanted anything to do with them, instead donating his money to the orphanage. This infuriated the leader of the organization and he sent numerous assassins, including other professional wrestlers, to punish him.
In Tiger Mask II (タイガーマスク二世), Naoto dies while saving a child, pushing him out of the path of a speeding car. The story begins with a new opponent called "Outer Space Mask" who bullies his way into the ring without representing any wrestling federation. Tatsuo Aku, once an orphan child from the "house of the children", was a fan of Naoto. He would put on his old hero's mask to become the new Tiger Mask.
