Hiroshima & Peace Memorial Park

The Lonely Planet states that Hiroshima is one of the most beautiful cities in Japan besides its horrible past.
Don't forgo the Atomic Bomb Dome (Genbaku Domu), the Peace Memorial Park, or the Hiroshima Peace Memorial Museum. You can see there what happened in this city in 1945. The presentation boards and the items on display are very impressive and cannot be compared with things you can see in White Sands.
