September 1, 1923. A 7.9 magnitude earthquake strikes off the coast of Japan. The shockwaves devastate Tokyo, Yokohama and surrounding areas.

In a downtown open space where earthquake survivors had taken refuge, the firestorm triggers an extremely rare "dragon twister" - a tornado filled with burning debris - which kills an astounding 38,000 in just 15 minutes. Known as the Great Kanto Earthquake, this disaster remains the deadliest in Japanese history, killing between 120,000 to 140,000 people. In the political and social chaos that follows, Japan is set on a new militaristic path towards the Second World War.
