The Institute of Science Tokyo (, Tà Âkyà  kagaku daigaku; branded as Science Tokyo) is a public research university in Tokyo, Japan. It was officially established on 1 October 2024, by a merger between the Tokyo Institute of Technology and Tokyo Medical and Dental University. The main campus is located in Ookayama, Meguro, with satellite campuses in Yokohama, Minato-ku, Bunkyo-ku, and Ichikawa.
The Tokyo Institute of Technology and Tokyo Medical and Dental University signed an agreement to merge into one university in October 2022. In November and December 2022, the two universities publicly solicited names for the new university on their websites.
On 19 January 2023, it was decided for the new university to use the name "Institute of Science Tokyo" ().
On 31 October 2023, the Japanese cabinet decided to amend the National University Corporation Act. The former National University Corporation Tokyo Institute of Technology () was renamed the National University Corporation Institute of Science Tokyo (), and the National University Corporation Tokyo Medical and Dental University () was dissolved at the same time. After being passed by the National Diet of Japan, the amendment took effect on 1 October 2024. The new university's headquarters is located in Meguro-ku, Tokyo, where the former Tokyo Institute of Technology headquarters was located.
In February 2026, China's Ministry of Commerce placed the Institute of Science Tokyo on its list of entities of concern and imposed import and export sanctions on the institute for its military affiliations.
The academic structure of the institute consists of 6 schools, 2 graduate schools, 2 faculties, and an institute for liberal arts.
The Institute of Science Tokyo has six campuses and several overseas bases.
Campus is the main campus of medical and dental school located in Bunkyà Â, close to Ochanomizu Station, which contains the main university hospital buildings and research facilities including the 126m-tall M&D tower. The Yushima Campus was originally part of the site of Tokyo Women's Higher Normal School (now Ochanomizu University), which was rented intermittently. During the time of the Tokyo Higher Normal School for Dentistry (the old system), the need for building expansion prompted the Ministry of Education to relocate the Tokyo Women's Higher Normal School to Otsuka, Bunkyo-ku in 1930, thus expanding the main campus. Present, the Yushima and Surugadai campuses are located on a limited amount of land and are densely packed with high-rise buildings with a maximum building-to-land ratio. In particular, the research building is a high-rise building, giving it a unique appearance for a national research institute. The ground area is 45,090m<sup>2</sup>, building area is 273,054m<sup>2</sup>.
Campus is also located close to Ochanomizu Station and houses Institute of Biomaterials and Bioengineering, M&D data center and the part of Medical Research Institute. The ground area is 5,597m<sup>2</sup>, building area is 18,028m<sup>2</sup>.
Campus is where undergraduate medical and dental students start their university studies and is home to the former Faculty of Liberal Arts, the Kohnodai Library, student dormitories, grounds and gymnasium, and other facilities.
