A museum dedicated to the promotion of peace through displays of war. Because it is an Osaka museum, it largely focuses on the effects of the bombings on Osaka in World War II. In the past, the museum also had exhibitions depicting the atrocities committed by Japan against China, Korea, and Southeast Asia. Sadly, however, those exhibitions were permanently removed in 2015 in response to pressure from conservative political groups. Exhibits have English explanations.

The Osaka International Peace Center (大阪国際平和センター, Ōsaka-kokusai-heiwa-sentā), also known as Peace Osaka (ピースおおさか, Pīsu-Ōsaka), 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.

In 2015, after pressures by members of the Japan Innovation Party, exhibits were changed; the section on U.S. air raids in Osaka Prefecture between December 1944 and August 1945 was expanded and items related to Japan's actions in Asia were removed. The spirit of the museum was radically altered and transformed: it became a conservative museum.
