Constructed in 593 A.D., Itsukushima (popularly known as Miyajima Shrine Island) was undamaged by the atomic bombing. The island consists of a series of temple buildings, tea houses and quaint shops. The long pier from which the torii in the sea can be seen offers majestic views of the inland sea and is considered one of Japan’s three most iconic views. As a UNESCO World Heritage site, it is considered a ‘must see’ for travelers to Japan.
