University of Tokyo

The University of Tokyo (東京大学, Tōkyō daigaku, abbreviated as Tōdai (東大) in Japanese and UTokyo in English) is a public research university in Bunkyō, Tokyo, Japan. Founded in 1877 as the nation's first modern university by the merger of several pre-westernisation era institutions, its direct precursors include the Tenmongata, founded in 1684, and the Shōheizaka Institute.

Although established under its current name, the university was renamed Imperial University (帝國大學, Teikoku daigaku) in 1886 and was further retitled Tokyo Imperial University (東京帝國大學, Tōkyō teikoku daigaku) to distinguish it from other Imperial Universities established later. It served under this name until the official dissolution of the Empire of Japan in 1947, when it reverted to its original name.

Today, the university consists of 10 faculties, 15 graduate schools, and 11 affiliated research institutes. As of 2023, it has a total of 13,974 undergraduate students and 14,258 graduate students. The majority of the university's educational and research facilities are concentrated within its three main Tokyo campuses: Hongō, Komaba, and Kashiwa. Additionally, UTokyo operates several smaller campuses in the Greater Tokyo Area and over 60 facilities across Japan and globally. UTokyo's total land holdings amount to 326 square kilometres (approximately 80,586 acres or 32,600 hectares), placing it amongst the largest landowners in the country.

As of 2025, UTokyo's alumni and faculty include 17 prime ministers of Japan, 20 Nobel Prize laureates, seven astronauts, and a Fields Medalist. Additionally, UTokyo alumni have founded some of Japan's largest companies, such as Toyota and Hitachi. UTokyo alumni also held chief executive positions in approximately a quarter of the Nikkei 225 companies in 2014, a fifth of the total seats in the National Diet in 2023, two-thirds of the prefectural governorships in 2023, and two-thirds of the justiceships at the Supreme Court of Japan in 2024.

The University of Tokyo traces its roots to three independent institutes founded during the Edo period (1603–1868). The oldest, a Shogun-funded Confucian school called Senseiden (先聖殿), was founded in 1630 by Razan Hayashi in Ueno. This school was renamed the Shoheizaka Institute (昌平坂学問所, Shoheizaka Gakumonjo) and came to be operated directly by the Tokugawa Shogunate in 1791 as part of the Kansei Reforms. The Tenmongata, founded in 1684, served the astronomical research and education arm of the Shogunate. It evolved into the Kaisei School (開成学校), a school for Western learnings, after the Meiji Restoration. The Kanda Otamagaike Vaccination Centre, established in 1858, evolved into a school of Western medicine called Tokyo Medical School (東京医学校, Tokyo Igakkō). Although plans to establish the country's first university had been in place just after the Meiji Restoration, it was not until around 1875 that it was decided to form the university by merging these schools.

The University of Tokyo was chartered on April 12, 1877, by the Meiji government. Corresponding to the fields covered by the predecessor schools, it started with four faculties: Law, Science, Letters, and Medicine. The Imperial College of Engineering later merged into the university as the Faculty of Engineering. In 1886, the university was renamed Imperial University, and it adopted the name Tokyo Imperial University in 1897 after the founding of the next imperial university, what is now Kyoto University. By 1888, all faculties had completed their relocation to the former site of the Tokyo residence of the Maeda family in Hongo, where they continue to operate today. Among the few extant structures built before this relocation is a gate called Akamon, which has since become a widely recognised symbol of the university.

During its initial two decades as a modern institution, UTokyo benefited from the contributions of European and American scholars. In 1871, the Meiji Government made a decision about the direction of academic disciplines: engineering was to be learnt from the United Kingdom, mathematics, physics, and international law from France, while politics, economics, and medicine were to be guided by German expertise. Additionally, agriculture and commercial law knowledge was to be sourced from the United States. Following this policy, UTokyo and its predecessor institutions sent their graduates to universities in these respective countries and also invited lecturers from them. However, by the 1880s, the Japanese government grew concerned over the spread of French republican and British constitutional monarchist ideals among the faculty and students, and eventually Minister of Education Takato Oki instructed the university to reduce the use of English as a language of instruction, and instead to switch to Japanese. This shift coincided with the return of UTokyo alumni who had completed their education in Europe, and these returnees began filling roles that had been predominantly held by foreign scholars.

The first half of the Interwar period in Japan was characterised by the spread of liberal ideas, collectively known as Taishō Democracy. This movement was ushered in by the concept of Minpon Shugi by Sakuzō Yoshino, as well as Tatsukichi Minobe's interpretation of sovereignty as inherent to the state rather than the monarchy. Both were alumni and professors at the Faculty of Law. Taking advantage of the widespread acceptance of such ideas, prime minister Takaaki Katō, an alumnus of UTokyo, extended suffrage to all males aged 25 and over in 1925, as promised in his manifesto. This liberal tendency was also shared among students, exemplified by the labour movement organisation the UTokyo Association of New People (東大新人会, Tōdai Shinjin-kai [ja]) and the UTokyo Settlement (東大セツルメント, Tōdai Settlement [ja]). However, strong reactions against these liberal and socialist ideas also emerged at the university, notably from Shinkichi Uesugi, who mentored and greatly influenced three future prime ministers among his students at UTokyo: Nobusuke Kishi, Eisaku Satō, and Takeo Fukuda.
