Keio University is a private, comprehensive higher education institution located on six campuses spread across the Greater Tokyo area. It offers an environment of academic and research excellence in a wide range of fields, and includes a university hospital. Founded in 1858, it is Japan's first modern institution of higher learning, and over the last century and a half it has established itself as a leader in Japan through its continued commitment to education, research and medicine. Keio has its origins in the school of Western learning established by Yukichi Fukuzawa, a school which soon evolved into a major center of learning. As a highly respected educator and intellectual, Fukuzawa was one of the pioneers of modern Japan. He aspired for Keio to become a model and leader of society, stressing the importance of learning that is based on jitsugaku, or "science". In today's changing world, Keio upholds its founder's spirit of science as it continues to fulfill his aspiration.
