OpenFieldTokyo University of Marine Science and Technology (TUMSAT / Kaiyodai) is Japan's sole national university dedicated exclusively to oceanography, naval architecture, maritime navigation, marine biotechnology, and aquatic food sciences.
Formed through the 2003 merger of the historic Tokyo University of Fisheries (est. 1888, Shinagawa campus) and Tokyo University of Mercantile Marine (est. 1875, Etchujima campus), TUMSAT operates a world-leading marine fleet including the training vessel Umitaka Maru. The university is internationally acclaimed for pioneering fish surrogate broodstock germ-cell transplantation, autonomous ship navigation, and marine food cold-chain logistics.
Admission to undergraduate degree tracks requires secondary school completion, national entrance examinations, and Japanese language ability (or English proficiency for select international programs). Master's and doctoral programs in Marine Science and Technology require a bachelor's or master's degree in marine science, biology, or engineering, and submission of a research proposal endorsed by a prospective TUMSAT laboratory supervisor.
Four-year curriculum at the Shinagawa campus examining the law of the sea, sustainable fisheries economics, marine protected areas (MPAs), and maritime environmental governance.
JABEE-accredited engineering program at the historic Etchujima campus, training students in autonomous ship navigation algorithms, marine engine propulsion, and hydrodynamics.
Four-year curriculum in marine fish breeding, recirculating aquaculture systems (RAS), aquatic disease immunology, and marine microbial genetics at Shinagawa and field research stations.
Two-year English-medium research master's degree exploring marine environmental conservation, oceanographic sensor data modeling, satellite remote sensing, and marine food chemistry.
Three-year doctoral dissertation research program producing global leaders in fish germ-cell manipulation, marine bioactive discovery, deep-sea ecology, and ocean biogeochemical cycles.
Japanese Government MEXT scholarship awarded via direct TUMSAT university recommendation to outstanding international graduate scholars entering master's or PhD tracks.
Intensive maritime navigational apprenticeship qualifying students for the First Grade Maritime Officer (Navigation/Engineering) license, conducting trans-Pacific training voyages.
