Miyajima island is only half an hour away from Hiroshima and a much more cheery place. It has the famous shrine gate in the sea which you might have seen in pictures of Japan. According to the Lonely Planet this is one of the top three views of Japan. I’m not sure what the other two views are but this view is pretty amazing indeed.
In addition to the attraction of the shrine gate, the island also has a lot of deer roaming freely. They’re not shy at all and come up to tourists quite a lot in search for food. It’s exciting and fun to be so close to them, until they surprise you while you’re watching the sunset and suddenly a deer has its head in your handbag.
