Stairs to Senjokaku
Senjokaku (The Hall of 1000 Tatami Mats) actually only has 857 tatami mats, but it is still impressive and stands as the largest building on the island of Miyajima. It was established in 1587 by Toyotomi Hideyoshi as a sutra repository and recitation hall. Because of its association with Hideyoshi, it is also known as a Toyokuni shrine of which there are many in Japan.
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.
