Tokyo suffered two major catastrophes in the 20th century. The 1923 Great Kantō earthquake left 140,000 dead or missing. World War II was the other disaster for the city. The Bombing of Tokyo from 1944 through 1945 killed between 75,000 and 200,000 people and destroyed half the city. This was almost as much damage as the atomic bombs of Hiroshima and Nagasaki combined.
