This building is a huge apartment built by the city of Hiroshima after the end of the war for those who lost their homes in World War II. There is a shopping street inside the building, and there is a farm on the roof, and the building itself has a unique structure that functions like a town. It is still operated by Hiroshima City, and priority is given to moving in people who have lost their homes due to natural disasters. At night, the silhouette of the building flips over into the river, creating a fantastic landscape.
