The Washington Post:

At 8:15 a.m. on Aug. 6, 1945, the first bomb exploded over Hiroshima killing, by some estimates, 140,000 people, and destroying 90 percent of the city. But near its hypocenter only one building was left standing.

Seventy years later, the Genbaku Dome — now known as the Hiroshima Peace Memorial — is part of a very different city that’s home to 1.2 million residents and filled with skyscrapers, apartment buildings and streetcars.

Armed with archival photographs, Reuters photographer Issei Kato revisited some of the same locations destroyed 70 years ago in both Hiroshima and Nagasaki.

On such a sombre day, it’s good to not only look back and remember what happened but also to look forward and see how the city has endured and prospered. The before and after pictures are truly heartening.
