The Institute Of Japanese Studies
Dr. Hisashi Kitanaka came out of London in the early 1980s with a doctorate in philosophy and a commitment to improving scholarship opportunities outside of Japan for young and promising Japanese students. He first worked with Trinity College, Dublin (hence the name “Trinity Foundation Programme”) to create something that did not exist at the time: a specialized programme that students could attend prior to beginning their degree course that would compensate for linguistic and cultural differences. Also hence the building name "Trinity Hall"
