The Graduate School of International Corporate Strategy (ICS) is a graduate school of business administration within Hitotsubashi University, a national institution of higher education under the jurisdiction of the Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT). The legal status of ICS is 'Professional Graduate School' (Senmonshoku Daigakuin, in Japanese). Hitotsubashi ICS was established in 1998 and welcomed its first incoming class in 2000. It is located at a campus in central Tokyo (Chiyoda Campus) about one hour from Hitotsubashi's main campus (Kunitachi Campus).
Hitotsubashi ICS's initial recognition and legitimacy comes from the fact that it is a Graduate School of Hitotsubashi University, one of Japan's leading universities. However, Hitotsubashi ICS is increasingly obtaining recognition and legitimacy in its own right, as an innovator in global professional education in Japan. In 2009, Hitotsubashi ICS received accreditation from ABEST21. It was one of four schools to be accredited, and the only one to receive the designation 'Excellence in Accreditation', for its world-class curriculum.
