Site of the Former Urakami Branch of Nagasaki Prison

The Site of the Former Urakami Branch of Nagasaki Prison is a preserved ruin within Peace Park that displays concrete walls and brick foundations. The remains show how the facility was constructed and organized when it operated as a working prison.

The prison was built in 1927 and operated for nearly two decades until the atomic bomb destroyed it in 1945. The foundations visible today were not fully uncovered until construction work exposed them decades after the war.

The prison held people from different backgrounds, including political prisoners whose stories reflect the tensions of that era. Visitors today can sense how this place functioned as part of the city's social structure.

The site sits within Peace Park where the ruins are easy to locate and view. The grounds are accessible throughout the year and provide a quiet space to walk and observe the remains.

During World War II, hundreds of inmates were sent daily to work at a nearby shipyard and returned to sleep at the facility. This arrangement reveals how the prison functioned as both a holding place and a labor source during wartime.
