Hokkaido University Graduate School of Medicine, Department of Neurosurgery

The Hokkaido University neurosurgery program was first formed in January 1958 under the leadership of Dr. Mitsuo Tsuru shortly after his return from neurosurgical training in the United States.  At that time, neurosurgery was a sub-group within the Departments of Surgery and Psychiatry.  In July 1958, Dr. Tsuru was elected lecturer of the Department of Psychiatry and 18 beds were installed for neurosurgery.  Beginning in 1961, the department began to offer a  six-year residency program for young neurosurgeons, modeled after the curricula Dr. Tsuru had observed in the United States. This program has since become a trademark of the department.  In 1965, Hokkaido University’s Department of Neurosurgery was established as a distinct department, becoming the third national-university-level neurosurgical department.

He was the first Japanese certified by the American Board of Neurological Surgery.  In 1965, the Hokkaido University Neurosurgery Department was officially established, and Dr. Tsuru was elected the first chairperson.  He spent most of his energies expanding neurosurgery in Hokkaido.  He has hosted many neurosurgical meetings, notably including the Japanese Society of Neurosurgery Annual Meeting (1970) and the Japanese Society of Neurology (1984), among others.
