Hiroshima Prefecture (広島県, Hiroshima-ken) is a prefecture of Japan located in the Chūgoku region on Honshu island.  The capital is the city of Hiroshima.  It has a population of around 2.8 million.
The area around Hiroshima was formerly divided into Bingo Province and Aki Province.  This location has been a center of trade and culture since the beginning of Japan's recorded history. Hiroshima is a traditional center of the Chūgoku region and was the seat of the Mōri clan until the Battle of Sekigahara.

- The Itsukushima Shrine in Miyajima, famed for filling with water and appearing to "float" during high tide.
