Iwakuni Castle

You can look out onto the Seto Inland Sea from the top floor of the castle.

Iwakuni Castle was built in 1608 by Kikkawa Hiroie, the first-generation lord of Iwakuni Domain. With the Nishiki River, which flows below, used as an external moat, the castle is located on top of the approximately 200-high Mount Shiroyama. Iwakuni Castle was demolished seven years after its construction due to the Shogun’s decree of “one castle in each domain”, and the current keep is a reconstruction built in 1962.
The castle interior boasts a variety of displays including a precise scale model of Kintaikyo Bridge, as well as photographs, weaponry, and armor.
The top floor of the castle has been made into a viewing platform, where you can enjoy gazing out onto the townscape of Iwakuni.
