This heart-wrenching museum documents the atomic bomb and its aftermath, from scale models of the city "before" and "after" to melted tricycles and other displays and artifacts related to the blast. Some are extremely graphic, evocative, and quite disturbing. The rest of the museum describes the post-war struggles of the hibakusha and an appeal for the abolition of nuclear weapons in the world today. Be warned: a visit here, while absolutely worthwhile, will ruin your day. Allow plenty of time afterward to decompress.
