Interview, visual and physical examination; measurement of temperature, height, weight, and blood pressure; rehabilitation; nutritional status evaluation, nutritional guidance, and dietary prescription.

[Laboratory Tests/Monitoring]

Blood tests; urinalysis; microbiological examination of pooled urine, sputum, and other samples; pathological and cytological examination of samples; physiological tests such as electrocardiography (ECG), sphygmography (pulse waves); pulmonary function, echocardiography, electroencephalography, ultrasonography, respirometry, expired gas analysis, electromyography (EMG), and thermography; plain x-ray and x-ray fluoroscopy ; plain CT and MRI; radioisotope (RI) tests; psychological tests; monitoring including ECG, transdermal oxygen saturation levels, arterial blood pressure, respiratory ventilation, bispectral index (BIS), and muscle relaxation; intradermal reaction tests (e.g., patch, intradermal, scratch, and tuberculin reactions and minimal erythema dose); and allergic skin tests. Blood tests to determine the presence or absence of infection of syphilis (Treponema antibody), hepatitis B (HBs antigen), hepatitis C (HCV antibody), HIV antibody (AIDS), which will be necessary for medical treatment such as surgery, dialysis, and angiography.
To help ensure the safety of patients, we use surveillance cameras to monitor patient status, when considered necessary for treatment purposes, in the operating room, ICU, HCU, CCU, Wards 4C, 8A, and 9A, radiotherapy room, Gamma Knife Center, MRI room, CT room, and fluoroscopy room.


Aspiration of sputum; nasal catheterization; indwelling bladder catheterization; examination and treatment of dental caries (tooth decay), periodontal disease, and dentures; and oral care.


Routine medication, routine injections, peripheral intravenous cannulation (establishment of an intravenous line), continuous subcutaneous cannulation, and oxygenation.
Even though the above medical treatment are performed by qualified medical personnel with appropriate levels of experience, complications such as bleeding may occur. In such cases, the complication is treated under ordinary health insurance coverage. We would like you to understand this arrangement in advance.

Communication of medication information when performing surgeries/ treatments that involve bleeding
For treatments such as surgery that involve bleeding, depending on the kind of medication you are normally taking, there is a possibility that we cannot perform the surgery/ treatment unless you temporarily stop taking that medication. Please inform the staff in detail about the medication you are taking when you are scheduled for a surgery or treatment involving the possibility of bleeding. If we are not informed about the detailed information of your medication and the surgery or treatment is called off, the patient may be held responsible for the expenses.

[Team Activities]

In order for us to enhance patient’s care, teams such as Infection Control Team, Nutrition Support Team, Palliative Care Team, Preventive Management for Diabetes Dialysis Team, Dementia Care Team, Urinary Continence Care Team, Pressure Ulcer Care Team, Neuropsychiatry Liaison Team, and Heart Care Team may be involved in treatment in addition to a team of clinical department, as needed.

[Medical Coordinator for International Patients and Medical Interpreter]

We accept non-Japanese patients while providing medical information in multiple languages, and accommodating cross-cultural, and religious consideration. We cooperate environmental improvement which Ministry of Health, Labor and Welfare of Japan promote for non-Japanese patients to receive medical treatment at ease.
