It was created by Joel Surnow and Robert Cochran, written by Shūkei Nagasaka and produced by Total Media Communication and 20th Century Fox Television, also commemorates the 60th anniversary of TV Asahi.

The series focuses on Genba Shidō, who works for the Tokyo–based Counter Terrorist Unit, his family, and a plot to assassinate Urara Asakura, who is set to become the first female prime minister of Japan.

The production of the show was allowed on the basis that 24 episodes would be presented in two seasons, a deviation from the typical release patterns of Japanese television dramas.

The producers were aware that, although the original series was enjoyed widely in Japan, adapting the story to a Japanese setting would be critiqued.

A commonly expressed concern mentioned by one reviewer was that the type of gun-related violence and terrorism portrayed in the American series would not be realistic in a Japanese setting, since a major terror attack had not occurred in Japan since the Tokyo subway sarin attack on 20 March 1995.
