Conditions Treated
Cerebrovascular Diseases in General (in Particular, Unruptured Cerebral Aneurysm, Arteriovenous Malformation, and Carotid Artery Stenosis), Brain Tumors (Various Types of Benign Tumors, Metastatic Tumors, Skull Base Tumors), etc.

Treatment Methods (Endovascular Treatment and Brain Surgery)

Endovascular treatment is a method in which the blood vessels in a disordered brain are treated from within without cutting open the skull. A thin tube, called a catheter, is inserted into a blood vessel from the base of a leg or from an elbow, and guided to the brain vessels by way of aortas for treatment. This method is less invasive for the patient during the treatment, physical recovery is fast after the treatment, and the scars are small. However, the method requires great expertise and only a few medical facilities and doctors have extensive experience.

Treatment Results

Number of Admissions of Emergency Patients 2,500 cases per year on average
Number of Outpatients 300 patients per day on average
Major Surgery Results (2010)
Surgical Clipping
(Brain Aneurysm, Subarachnoid Cerebral Hemorrhage, etc.)
81 cases
Endovascular Surgery (Brain Aneurysm) 59 cases
Bypass Surgery
(Cerebral Infarction, Moyamoya Disease, etc.)
17 cases
Cardiac Catheter Test /Surgery (PCI etc.) 740 cases

In the case of unruptured cerebral aneurysms, endovascular vessel coil embolization is performed, in which a shape-memory platinum coil or the like is inserted into the aneurysm to prevent blood vessel rupture. Endovascular treatment may not be suitable depending on the shape of the aneurysm itself and/or the condition of a parent artery. In this case, a clipping surgery is performed to isolate the base of the aneurysm in craniotomy, which also is a surgical procedure that requires high-level techniques.

In addition, we perform carotid stent placement, in which a catheter is inserted into a very narrow carotid and a metal tube called a stent is placed to maintain the blood flow, as well as endovascular treatment for tumors, in which an embolizing material is inserted into the blood vessel that supplies a tumor with nutrients.

The endovascular treatments and surgeries performed at our hospital are both at a very high level, and so we can choose the safest, most appropriate method in accordance with the condition of the patient.

Features of Our Hospital

Our hospital was established in 1995 as Kitahara Brain Surgery Hospital on the two principles of: “better treatment at lower cost for society and people” and “promoting medical treatment in Japan as an export industry.” In recent years, we have been contributing to intranational and international efforts through medical and educational activities, such as the ongoing plan to establish a hospital in Cambodia. We want not only to provide patients in South East Asia with high-quality treatment in Japan, but also to boost education and training for local medical staff.

In addition to Japanese, we have staff who can speak English, French, and Chinese, and we intend to support Spanish and South East Asian languages.

Moreover, we have been improving our cancer center to provide various medical treatments including for metastatic brain tumors. We aim to cover the treatment of all types of cancer tumors not only by performing advanced endovascular and surgical treatments but also through chemotherapy and radiotherapy with the introduction of a stereotactic radiotherapy system.

A Message to International Patients from Our Hospital

Dr. Yoshinobu Shioda
Dr. Shigemi Kitahara
Chair of the Board of Directors,
Kitahara Neurosurgical Institute

We are proud to provide patients with consistent treatment. It is crucial to provide reliable, high-quality medical treatment for international residents in Japan, who may feel concern about receiving medical treatment in the country due to language difficulties. Currently, doctors from South East Asia, whom we welcome as trainees, assist patients by also acting as medical interpreters, and are of great value to our patients from overseas. Nevertheless, an unexpected situation or complication can occur with any treatment, and our international patients must understand this before visiting. We offer high-quality medical treatment in the general field of cranial nerve disease, including both excellent manual techniques and rehabilitation.

Overview of the Treatment Schedule (Model Case: Brain Endovascular Treatment for Unruptured Cerebral Aneurysm)

You are asked to send MRI images, MRA images, and so forth of the aneurysm, recorded at your local hospital before visiting Japan. If such images are insufficient, we will take more images after your arrival in Japan.

Overview of Treatment Schedule


External View of Our Hospital Surgery Waiting Room Multi Occupancy Room (Room with Four Beds) Rooftop Garden
External View of Our Hospital Surgery Waiting Room
This bright, spacious room has glass walls and an atrium, to soothe the families and relatives waiting for the patient undergoing surgery. They can view the surgery on the video screen in the waiting room or through a window on the side of the operating theater, which has frosted glass normally but can be made transparent as necessary. This ingenious device for providing information helps make families less anxious while waiting for the surgery to be completed.
Multi Occupancy Room (Room with Four Beds) Rooftop Garden
If weather permits, walking rehabilitation is performed on the rooftop.
