Tokyo prepares for the 'Big One'

Seen from atop the towering Tokyo Skytree, the patchwork of narrow alleyways and ramshackle houses that make up Tokyo’s Sumida district is a picturesque throwback to the Japan of yesteryear.

But this densely packed district—home to about 230,000 people—is one of the Japanese capital’s most at-risk neighborhoods, where officials are busily preparing for the “Big One”, a long-expected monster earthquake that experts say will one day rock the city of 12 million.
