Tokyo Magnitude 8.0

There is an estimated 70% or higher chance that a magnitude 7.0 earthquake will hit Tokyo within the next 30 years. In 2012, Mirai, a first-year middle school girl, visits Tokyo's artificial Odaiba Island with her brother Yuuki for a robot exhibition at the start of summer vacation. A massive quake measuring 8.0 on the JMA scale strikes from an ocean trench, the famous Tokyo Tower and Rainbow Bridge crumble and collapse, and Tokyo's landscape is transformed in seconds. With help from Mari, a motorcycle delivery woman they meet on Odaiba, Mirai and Yuuki try to make their way back to their home in Setagaya, in western Tokyo.
