Miyajima Public Aquarium opened as a prefectural aquarium in 1959.[3] It was transferred to Miyajima, Hiroshima as a town aquarium in 1967, and its buildings were reconstructed in 1981. In 2005, the aquarium was once again transferred to Hatsukaichi, Hiroshima as a city aquarium. In 2011, a roof was installed near the aquarium entrance as part of building renewal efforts to combat weather concerns.[4]
