Of the numerous disasters, both natural and man-made, to strike Japan during the 20th century, the Great Kantō Earthquake was among the worst, and the most significant. The massive earthquake struck the Japanese capital region, including the cities of Tokyo and Yokohama, shortly before noon on Saturday, September 1, 1923, causing immense physical destruction. Buildings collapsed, crushing their occupants, and a tsunami assaulted miles of coastline, depositing boats well inland and dragging people, structures, and debris out to sea. In both Tokyo and Yokohama, the tremors set off firestorms that raged for days across the dense, wooden cityscapes. In all, the earthquake left perhaps 140,000 dead and more than 2 million homeless, transforming East Asia's most prosperous and modern urban area into a scorched, burned-out wasteland. On the day of the earthquake, according to the Buddhist figure Takashima Beihō, "Nature raged all at once, collapsing the pillars of the sky and snapping the axis of the earth. The big city of Tokyo, the largest in the Orient, at the zenith of its prosperity, burned down and melted away over two days and three nights."
