Okinawa, Japan

The Okinawa Institute of Science and Technology Graduate University is an interdisciplinary graduate school located in Onna, Okinawa Prefecture, Japan. The school offers a 5-year PhD program in Science. Over half of the faculty and students are recruited from outside Japan, and all education and research is conducted entirely in English.The university has no departments—OIST researchers conduct multi-disciplinary research in neuroscience, mathematical and computational science, physics, chemistry, integrative biology and molecular, cell, and developmental biology. The university received accreditation on November 1, 2011, and began classes in September 2012.OIST relies on public subsidies paid by the Japanese government. The government subsidy for OIST comes in two areas: a subsidy for operations and a subsidy for facilities. Wikipedia.
