TheUniversity of Osaka (大阪大学,Ōsaka daigaku), abbreviated asUOsaka orHandai (阪大), is anationalresearch university inOsaka, Japan. The university traces its roots back toEdo-era institutionsTekijuku (1838) andKaitokudo (1724), and was officially established in 1931 as the sixth of theImperial Universities in Japan, with two faculties:science andmedicine. Following thepost-war educational reform, it merged with three pre-warhigher schools, reorganizing as a comprehensive university with five faculties: science, medicine, letters, law and economics, andengineering.[6] After the merger withOsaka 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.
The academic traditions of the University of Osaka reach back to theKaitokudō (懐徳堂), anEdo-period school for local citizens founded in 1724, and theTekijuku (適塾), a school ofRangaku forsamurai founded byOgata 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.[6]UOsaka traces its modern origins back the founding ofOsaka Prefectural Medical School in downtownOsaka City in 1869. The school was later designated theOsaka 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 formOsaka Imperial University in 1931. Osaka Imperial University was the sixthimperial 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 theNakanoshima campus in downtown Osaka to theSuita campus, completing the implementation of the university's plan to integrate the scattered facilities into the Suita andToyonaka campuses. In October 2007, a merger between UOsaka and theOsaka University of Foreign Studies inMinoh was completed. The merger made UOsaka one of two national universities in the country with a School of Foreign Studies, along with theTokyo University of Foreign Studies. The merger also made UOsaka the largest national university in Japan.
TheToyonaka campus is home to faculties ofHumanities,Law,Economics,Science, andEngineering 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.
TheSuita campus houses faculties ofHuman Sciences,Medicine,Dentistry,Pharmaceutical Sciences, andEngineering. 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 theUniversity of Osaka Hospital and the Nationwide Joint Institute of Cybermedia Center and Research Center for Nuclear Physics.
TheMinoh campus was incorporated following the merger with theOsaka 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.
In addition to these three campuses, the former Nakanoshima campus, the university's earliest campus located in downtown Osaka, served as the hub for the faculty of medicine until the transfer to the Suita campus was completed in 1993.[7] In April 2004, the Nakanoshima campus became the university's Nakanoshima Center, serving as a venue for information exchange, adult education classes, and activities involving academic as well as non-academic communities.
The University of Osaka consists of 11 undergraduate schools and 15 graduate schools. The undergraduate schools include Letters, Human Sciences, Foreign Studies, Law, Economics, Science, (Faculty of) Medicine, Dentistry, Pharmaceutical Sciences, Engineering, and Engineering Science. At postgraduate level, the schools cover a range of disciplines: Humanities, Human Sciences, Law and Politics, Economics, Science, Medicine, Dentistry, Pharmaceutical Sciences, Engineering, Engineering Science, International Public Policy, Information Science and Technology, Frontier Biosciences, Law (Law School), and the United School of Child Development, which is a collaboration withKanazawa University,Hamamatsu University School of Medicine,Chiba University, and theUniversity of Fukui.[8]
UOsaka also has 21 research institutes, 4 libraries, and 2 university hospitals.[9]
The University of Osaka's School of Human Sciences on the Suita Campus hosts an English-medium four-year undergraduate degree program.[11] The program started in 2011 as a result of the national government's G30 (Global 30) Project. Although the government ended the G30 Project in 2014[12] and replaced it with theTop Global University Project, the OU Human Sciences International Undergraduate Program continues. Areas of study include sociology, anthropology, philosophy, education, behavioral sciences, psychology, human development, and area studies. Focus is on the development of an interdisciplinary, international, and problem-solving orientation to research and education. The degree programme is based on international benchmarking standards, has competitive entry requirements and attracts students from all over the world. The current director of this programme is Beverley Yamamoto, who leads a UNESCO Chair in Global Health and Education.
UOsaka's Graduate School of Humanities hosts another English-medium program in GlobalJapanese Studies for graduate students, one of the Graduate Programs for Advanced Interdisciplinary Studies.[13]
The University of Osaka has academic exchange agreements with a large number of universities in other countries and regions. These academic exchange agreements have been concluded on the university-to-university level and also on the school-to-school level. Joint research as well as researcher and student exchanges take place between UOsaka and these universities and schools. At certain of these universities and schools, it is possible for undergraduate and graduate students to take classes and/or engage in research for up to one year without paying tuition to that university or school while retaining their enrollment status at their home university. Inter-university agreements number is 156, and inter-faculty agreements number is 651 as of May 1, 2024.[14]
