Development and production

The series was first announced at the 2009 Tokyo Anime Fair, denoting that it would replace Eden of the East in Fuji TV's noitaminA well-rated anime timeblock and would be co-produced by Bones and Kinema Citrus.[1][2] The series' setting is based upon the prediction that there is 70% or higher chance of an earthquake measuring 7.0 magnitude on the Richter scale hitting Tokyo in the next 30 years, with the series illustrating the consequences of a 8.0 scale earthquake affecting the city.[1][2] Bones stated that it would try to realistically depict the after-effects of such a situation and that it would collect and tabulate research on previous earthquakes and interview individuals who were affected by them.[1][2]

The series features the efforts of the Japan Ground Self-Defense Force, Japan Coast Guard, Tokyo Fire Department and Tokyo Disaster Medical Assistance Team in assisting recovery efforts after the initial earthquake and its recurring aftershocks. FNN newscaster Christel Takigawa also features as a guest, reporting on the earthquake and assuming the role of a "navigator" during the series.[3]


The series uses two pieces of theme music. "Your Song" (キミノウタ Kimi no Uta?) by Abingdon Boys School is used for the opening theme, while "M/elody" by Shion Tsuji is used for the ending
