University of Osaka

The University of Osaka (大阪大学, Ōsaka daigaku), abbreviated as UOsaka or Handai (阪大), is a national research university in Osaka, Japan. The university traces its roots back to Edo-era institutions Tekijuku (1838) and Kaitokudo (1724), and was officially established in 1931 as the sixth of the Imperial Universities in Japan, with two faculties: science and medicine. Following the post-war educational reform, it merged with three pre-war higher schools, reorganizing as a comprehensive university with five faculties: science, medicine, letters, law and economics, and engineering. After the merger with Osaka University of Foreign Studies in 2007, UOsaka became the largest national university in Japan by undergraduate enrollment. The official name of the university in English has been changed from "Osaka University" to "The University of Osaka (UOsaka)" as of April 2025.

UOsaka is one of the most productive research institutions in Japan. Numerous prominent scholars and scientists have attended or worked at UOsaka, such as Nobel Laureate in Physics Hideki Yukawa, Nobel Laureate in Medicine Shimon Sakaguchi, manga artist Osamu Tezuka, Lasker Award winner Hidesaburō Hanafusa, author Ryōtarō Shiba.

The academic traditions of the University of Osaka reach back to the Kaitokudō (懐徳堂), an Edo-period school for local citizens founded in 1724, and the Tekijuku (適塾), a school of Rangaku for samurai founded by Ogata Kōan in 1838. The spirit of the university's humanities programmes is believed to be intimately rooted in the history of the Kaitokudō, whereas that of the natural and applied sciences is based upon the traditions of the Tekijuku. UOsaka traces its modern origins back the founding of Osaka Prefectural Medical School in downtown Osaka City in 1869. The school was later designated the Osaka Prefectural Medical College with university status by the University Ordinance (Imperial Ordinance No. 388) in 1919. The Medical College merged with the newly founded College of Science to form Osaka Imperial University in 1931. Osaka Imperial University was the sixth imperial university in Japan. Osaka Technical College was incorporated to form the School of Engineering two years later. The entire university was renamed Osaka University in 1947.

After merging with Naniwa High School and Osaka High School as a result of the government's education system reform in 1949, UOsaka started its postwar era with five faculties: Science, Medicine, Engineering, Letters, and Law. Since that time new faculties and research institutes have been established, including the first Japanese School of Engineering Science and the School of Human Sciences which covers such cross-disciplinary research interests as broadly as psychology, sociology, and education. Built on the then-existing faculties, ten graduate schools were set up as part of the government's education system reform program in 1953. Two more graduate faculties were added in 1994.

In 1993, Osaka University Hospital was relocated from the Nakanoshima campus in downtown Osaka to the Suita campus, completing the implementation of the university's plan to integrate the scattered facilities into the Suita and Toyonaka campuses. In October 2007, a merger between UOsaka and the Osaka University of Foreign Studies in Minoh was completed. The merger made UOsaka one of two national universities in the country with a School of Foreign Studies, along with the Tokyo University of Foreign Studies. The merger also made UOsaka the largest national university in Japan.

The Toyonaka campus is home to faculties of Humanities, Law, Economics, Science, and Engineering Science. It is also the academic base for Graduate Schools of International Public Policy, Language and Culture, a portion of Information Science, and the Center for the Practice of Legal and Political Expertise. All undergraduates attend classes on the Toyonaka campus during their first year of enrollment. Sports activities are primarily concentrated on the Toyonaka campus, with the exception of tennis, which is located in Suita.

The Suita campus houses faculties of Human Sciences, Medicine, Dentistry, Pharmaceutical Sciences, and Engineering. It contains the Graduate School of Frontier Biosciences and a portion of the Graduate School of Information Science and Technology. The campus is also home to the University of Osaka Hospital and the Nationwide Joint Institute of Cybermedia Center and Research Center for Nuclear Physics.

The Minoh campus was incorporated following the merger with the Osaka University of Foreign Studies in October 2007. The Minoh campus is home to the School of Foreign Studies, the Research Institute for World Languages, and the Center for Japanese Language and Culture.
