Miyajima (宮島) 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. Miyajima is a romantic place, best enjoyed by staying overnight at one of the island's ryokan. While there are usually many day tourists, in the evening the area becomes much quieter and more peaceful. There are also wild deer on the island that have become accustomed to people. In the day the deer wander around the same sites as the tourists, and in the evening they sleep along the walking paths.

The Hiroshima Peace Memorial Museum is the largest of Hiroshima's sites related to the atomic bomb. Designed by renowned architect Tange Kenzo (1913-2005), the museum opened in 1955, and in 2006 it was designated an Important Cultural Property of Japan. The museum consists of two adjacent buildings inside Peace Memorial Park. The main hall houses an extensive collection of artifacts from the time of the bombing, while the east building is focused on peace education through a variety of media. The main hall recently underwent major renovation, and its collection is now even more powerful and moving.

Hiroshima's Peace Memorial Park (平和記念公園, Heiwa Kinen Kōen) is one of the most prominent features of the city. Even visitors not looking for it will likely stumble upon the large park of over 120,000 square meters. Its trees, lawns, and walking paths are in stark contrast to the surrounding downtown area. Before the bomb, the area of what is now the Peace Park was the political and commercial heart of the city. For this reason, it was chosen as the pilot's target. Four years to the day after the bomb was dropped, it was decided that the area would not be redeveloped but instead devoted to peace memorial facilities.

The centuries-old Itsukushima Shrine (厳島神社, Itsukushima Jinja) on Miyajima is the source of both the island's fame and its name. Formally named Itsukushima, the island is more popularly known as "Miyajima", literally "shrine island" in Japanese, thanks to its star attraction. The shrine is known worldwide for its iconic "floating" torii gate. The shrine and its torii gate are unique for being built over water, seemingly floating in the sea during high tide. The shrine complex consists of multiple buildings, including a prayer hall, a main hall and a noh theater stage, which are connected by boardwalks and supported by pillars above the sea.
