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. When YCU was converted into an independent administrative entity, the Business, International Liberal Arts, and Sciences faculties merged to form the International College of Arts and Sciences. YCU made a new start as a two-faculty system including this new faculty and the School of Medicine. YCU has been working to create a university that attracts a lot of excellent students while keeping the original spirit of the time of foundation, such as an advanced learn-by-doing teaching method and an emphasis on contribution to the community and society.
