The , also known as , is a peace museum established in August 1991 based in the city of Osaka, Japan. It focuses on the destruction of the city during World War II and the broader themes of the tragedy of war and the importance of peace. It is funded by Osaka city and Osaka Prefecture.

When it became clear that the plans were to "drastically" reduce the material on Japan's aggression, the Japan Times printed an editorial calling on the museum to reconsider and stated that "The plan by the center — which is dedicated to studies of the war and efforts to foster peace — contradicts its purported independence." Exhibits before 2015 Exhibition Room A, on the second floor of the Osaka International Peace Center, covered the bombing of Osaka and other factors of Japanese domestic life during the last four years of the Pacific War, mentioning neighborhood associations, school mobilization, nationalistic textbooks, and civil defense measures.
