It is really a world heritage site of great historical value, as a historical witness to the horror of atomic bombing. The "Revived A-Bomb Tramcars" are not so famous as the "A-Bomb Dome" among the people except in Hiroshima. Nevertheless, both are also Hiroshima's peace monument appealing for the abolition of nuclear weapons and the realization of lasting world peace. Therefore, restoration and conservation of industrial facilities as cultural properties can be a kind of "Business & Technology Transfer" from "industry" sector to "culture" sector.
