Itsukushima jinja is a world heritage site on Hiroshima prefecture's Miyajima island. The shrine and it's gate are regarded as one of Japan's great views because of its large torii which stands over 16 meters tall. The shrines dates back to the days of Taira Kiyomori and features the oldest Noh stage in Japan. Another amazing feature of the shrine is that it was built over water. The appearance changes as the tide rises and falls.
Miyajima is a sacred island a few minutes from the mainland which can be accessed by ferry. It is a short distance from Hiroshima and Iwakuni and makes for an excellent day trip. The highlight of the islands, besides the roaming deer and monkeys, is Itsukushima jinja. The large torii there is one of Japan's three greatest views--I totally agree with this although I have never been to Amanohashidate. It also includes other temples, shrines, nature, and of course shopping. Highly recommended.
