Iwakuni Castle (Iwakuni-jo) was completed by Kikkawa Hiroie, an influential daimyo of the region, in 1608. Everything but the stone wall and moat was demolished seven years after its completion, however, following the law promulgated by the Edo shogunate which ruled Japan, which did not allow more than one castle per domain. The existing donjon was built in 1962 and it is a four-tiered, ferroconcrete structure. Samurai swords and other arms used in battle such as helmets and suits of armor are exhibited on the first to third floors. The fourth floor is an observation level.
