100 years have passed since the Great Kanto Earthquake of 1923. Although filmed records of its aftermath exist, the footage held flaws making it difficult to identify locations or times, obscuring the reality of how citizens of Tokyo faced this overwhelming disaster.

This program opens a new window into the events surrounding the disaster that had once been shrouded in mystery.
