Yokohama City University (YCU) has shared its path with the City of Yokohama which celebrated in 2009 the 150th anniversary of the opening of its port to the world. The origin of Yokohama City University can be traced back to the Yokohama School of Commerce founded in 1882. Since the opening of the port, Yokohama turned into a center of trade in Japan. The Yokohama School of Commerce was established to develop human resources equipped with western commercial techniques and then developed into the Yokohama City College of Commerce (Y college), which is the origin of Yokohama City University. Another origin of YCU is the Juzen Hospital of Nogeyama in 1874. Juzen Hospital then turned into Yokohama Municipal Medical College, which has developed into today’s YCU Hospital and School of Medicine. YCU became an independent administrative entity in 2005, and has since offered curricula in International Liberal Arts, Economics, Business Administration and Science, as well as in Medicine and Nursing. Now, for the first time in the metropolitan area, YCU has launched a new faculty called "School of Data Science" in the spring of 2018 in response to the new social trend and demand to create value from the considerable amount of data our societies generate. YCU will continue to contribute to the modern community and society by nurturing globally minded human resources who are able to meet the needs of our rapidly changing world.
