General Information

Department of Neurosurgery of the Tokyo Women’s Medical University Adachi Medical Center is designated as official training center of the World Federation of Neurosurgical Societies (, and we regularly accept young colleagues from abroad for upgrading their professional knowledge in our facilities. During their fellowship, trainees are closely involved in daily neurosurgical team work with selection of the subspecialty of their particular interest. The main options include (but not limited to) diagnosis and surgical treatment of epilepsy, management of stroke, management of acute aneurysmal subarachnoid hemorrhage, endovascular surgery, and brain trauma. Fellows also attend regular rounds in wards and neuro intensive care unit, and are allowed to assist during elective and emergency surgical procedures performed by their supervisor. In our OR fellows can get an experience with application of advanced microsurgical, stereotactic, endoscopic, and endovascular techniques, particularly with the use of such novel neurosurgical devices as frameless neuronavigation system, ORBEYE exoscope, and Robotized Stereotactic Assistant (ROSA). Fellows also have an option to upgrade their manual skills in the 24/7 microsurgical laboratory. Fellows are encouraged to participate actively in educational activities (such as Journal Club) and to conduct clinical research work with presentation of its results and their publication in the international journals. Upon decision of their supervisor, during the fellowship period trainees are allowed to attend selected neurosurgical conferences held in Japan. Formal certificate is provided at the end of training period.
