Stroke is one of the leading causes of long-term disability and loss of independence. In addition, approximately one-third of dementia cases are believed to be related to stroke or other cerebrovascular diseases.
Yet, brain abnormalities also can progress silently without noticeable symptoms.

A Brain Dock (preventive MRI brain screening) may help detect conditions such as silent strokes, brain aneurysms, and other vascular abnormalities before symptoms appear. Regular brain screening can help identify future risks of stroke and cognitive decline at an early stage, supporting long-term brain health, independence, and quality of life.

In Japan, healthcare is not only focused on treating illness after symptoms appear, but also on preventing disease before it develops.
One example of this preventive healthcare culture is the “Brain Dock” — an MRI-based brain screening program that is unique to Japan.

In many countries, undergoing a brain MRI without symptoms is not considered routine.
In contrast to that in Japan, regular brain screening is widely accepted as a way to identify future health risks at an early stage.

At our clinic, you can receive a high-quality MRI brain screening for ¥25,500.
The entire process — from arrival to completion — takes approximately one hour, and our English-speaking concierge team will support you throughout your visit. Experience Japan’s unique preventive healthcare culture for yourself.

In Japan, regular health checkups and medical screenings are a common part of preventive healthcare culture.
However, many general health screenings do not include detailed brain examinations, and even when they do, they often rely only on CT scans.

A CT scan is mainly used to detect abnormalities that are happening at the present moment.
It is particularly effective for diagnosing brain hemorrhage, but it cannot clearly evaluate the condition of brain blood vessels and may miss small strokes or subtle vascular abnormalities.

As a result, CT scans alone may not be sufficient to detect:

• Narrowing or blockage of brain blood vessels
• Brain aneurysms, which can cause subarachnoid hemorrhage

A Brain Dock, on the other hand, uses both MRI and MRA imaging.
MRI provides a more detailed view of the brain than CT and can detect small abnormalities such as silent strokes that may not cause noticeable symptoms.

In addition, MRA allows visualization of the brain’s blood vessels, helping identify vascular narrowing or brain aneurysms that may increase the future risk of stroke or subarachnoid hemorrhage.
A Brain Dock is designed not only to evaluate the brain’s current condition, but also to identify future risks early — allowing preventive care and medical follow-up before serious symptoms develop.

Speed Brain Check-up:
¥25,500 (tax included)

• Brain MRI / MRA
• Cervical (Neck) MRA
• No doctor consultation on the day of the examination
• A detailed Brain Dock report and imaging data will be mailed to your home at a later date
• Short examination time (approximately 40 minutes)

MRI examinations use strong magnets and electromagnetic waves. Bringing metal objects into the MRI room may cause burns due to heat generated by the metal, and may also affect the accuracy of the images obtained.

Please review the following precautions carefully before your examination.

Patients who meet any of the following criteria are not eligible to undergo an MRI examination at our clinic:

• People who use a cardiac pacemaker, implantable cardioverter defibrillator (ICD), or artificial heart valve.
• People who use a cochlear implant or middle ear implant.

• 

  Using a cardiac pacemaker, implantable cardioverter-defibrillator (ICD), or artificial heart valve

• 

  Using a cochlear implant or middle ear implant

Patients with any of the following conditions may not be able to undergo an MRI scan.

If you would like to schedule an appointment, please contact us in advance to discuss your eligibility.

• People who use a deep brain stimulation device or an older cerebral aneurysm clip.
• People who have recently had a vascular stent or vascular filter implanted.
• People who use magnetic or metal dentures, or dental implants.
• People with tattoos or permanent makeup.
• People who use an intrauterine contraceptive device (IUD).
• People who are in the early stages of pregnancy (less than 4 months) or who may be pregnant.
• People who have metal inside their body whose material composition cannot be confirmed.
• People who have claustrophobia or a tendency toward claustrophobia.

•
