Located in Naka-no-shima between the Dōjima River and the Tosabori River in Osaka, the Osaka Science Museum opened in 1989 to commemorate the 100th anniversary of Osaka City, its construction funded by a 6.5 billion yen donation from Kansai Electric. Designed by Takenaka Corporation, the museum sits above the subterranean National Museum of Art and centers on the theme "The Universe and Energy." Its four-floor permanent exhibition comprises 200 interactive science displays, while a separate planetarium features a 26.5-meter-radius dome—the world's seventh largest—upgraded in 2004 with next-generation digital projection. The museum preserves significant artifacts including Japan's first planetarium (a Carl Zeiss II model from 1937), the Cockcroft-Walton accelerator, and resources documenting early Japanese chemistry and radio astronomy. The building's site holds historical importance: it once housed Osaka University facilities where physicist Hideki Yukawa developed his meson theory, which earned him the Nobel Prize, and served as Japan's first location for measuring cosmic radio waves.
