On March 11, 2011 the photographer Koichiro Tezuka was in a helicopter on the way back from Aomori prefecture, North Japan, to Tokyo. While in the air a magnitude 9.0 earthquake hit the Pacific coast of Tôhoku. It was almost probably the strongest earthquake since 1.000 years. The earthquake caused surprisingly minor damage considering the magnitude of the quake.
Koichiro Tezuka immediately began to photograph the earthquake damages, but soon they had to do a stopover at Sendai Airport, Miyagi Prefecture for to refuel the helicopter. But the airport, located very close to the sea was closed due to the earthquake.
