Former Shiroyama National School A-bomb Remains

West of Nagasaki's hypocenter, the surviving stairwell of Shiroyama National School makes the destruction of an educational community tangible. Two three-storey reinforced-concrete school buildings stood here when the atomic bomb exploded on 9 August 1945. Their interiors were devastated; fire consumed the upper floors of the northern building. The school community suffered enormous losses, alongside people working at the site for Mitsubishi's armaments enterprise.

Most of the old buildings were eventually demolished. The retained northern stairwell contains scorched wooden blocks embedded in its concrete frame, originally used to attach interior fittings. They are direct physical evidence of the fire, rather than a reconstructed display. Following a proposal from pupils, the surviving section became the Shiroyama Elementary School Peace Memorial Hall in 1999. Photographs, objects and a model help visitors understand the former school.

The surrounding campus remains a working elementary school. The memorial hall is free to visit during its published hours, with New Year closures and occasional maintenance closures. The city's tourism guidance asks visitors to contact the site in advance. Access to the memorial does not imply unrestricted access to classrooms or the school grounds.
