The Osaka Science Museum is a science museum in Naka-no-shima, Kita-ku, Osaka, Japan. The museum is located between the Dōjima River and the Tosabori River, above Osaka's subterranean National Museum of Art. Opened in 1989, the museum was constructed to mark the 100th anniversary of Osaka City. The construction was funded through a 6.5 billion yen donation toward building costs from Kansai Electric. Its theme is "The Universe and Energy". Before the war a similar museum opened in 1937.
