Tokyo University of Marine Science and Technology (東京海洋大学, Tōkyō Kaiyō Daigaku) is a national university in Japan. The main campus (Shinagawa Campus) is located in Minato, Tokyo and another campus (Etchujima Campus) is in Koto, Tokyo. The university was established with a merger of two national universities, namely, Tokyo University of Mercantile Marine (東京商船大学, Tōkyō Shōsen Daigaku) in Koto, Tokyo and Tokyo University of Fisheries (東京水産大学, Tōkyō Suisan Daigaku) in Minato, Tokyo. Tokyo University of Mercantile Marine was founded in November 1875 by Iwasaki Yataro as Mitsubishi Nautical School (三菱商船学校, Mitsubishi shōsen gakkō). In 1882 it became a national school named Tokyo Nautical School (東京商船学校, Tōkyō shōsen gakkō). In 1902 the school was removed from Reiganjima to present-day Etchujima Campus. In 1925 the school became Tokyo Nautical College (東京高等商船学校, Tōkyō kōtō shōsen gakkō). In April 1945, during World War II, three nautical colleges at Tokyo, Kobe and Shimizu were merged into one college simply named Nautical College, which was located in Shimizu. In 1949 the college was developed into the University of Mercantile Marine under Japan's new educational system.
