In 2025, 1.68 million travelers from overseas went to Hiroshima prefecture, Japan Tourism Agency data shows. Foreign visitor traffic at the Peace Memorial Museum has continued to soar, climbing to over 40% of the total in the April-June quarter. An official at the Hiroshima Tourism Policy Department recalls the 2016 visit by Barack Obama -- the first by a sitting U.S. president -- as a "turning point." The ensuing global attention spurred the city to form a roundtable in 2017, including survivors of the Aug. 6, 1945, atomic bombing, and create an example itinerary for foreign visitors. Travel to places associated with tragedies, such as the former site of the Auschwitz concentration camp, often is called "dark tourism." Hiroshima prefers to describe visits to the city as "peace tourism."
