Hiroshima is the principal city of the Chugoku Region and home to over a million inhabitants.When the first atomic bomb was dropped over Hiroshima on August 6, 1945, the city became known worldwide for this unenviable distinction. The destructive power of the bomb was tremendous and obliterated nearly everything within a two kilometer radius.After the war, great efforts were taken to rebuild the city. Predictions that the city would be uninhabitable proved false. Destroyed monuments of Hiroshima's historical heritage, like Hiroshima Castle and Shukkeien Garden, were reconstructed. In the center of the city a large park was built and given a name that would reflect the aspirations of the re-born city: Peace Memorial Park.Miyajima is a small island less than an hour outside the city of Hiroshima. It is most famous for its giant torii gate, which at high tide seems to float on the water. The sight is ranked as one of Japan's three best views.While officially named Itsukushima, the island is more commonly referred to as Miyajima, Japanese for "shrine island". This is because the island is so closely related to its key shrine, Itsukushima Shrine, in the public's mind. Like the torii gate, the shrine's main buildings are built over water.
